Food Hygiene Essentials

Most people around the world have heard about the medicinal benefits of Chinese herbal remedies. These time tested traditional potions have maintained the one of the worlds largest and indeed greatest cultures for thousands of years. Today, few would dispute the benefits of herbal medicines in the hands of experienced and reputable practitioners.

In the advent of the computer age Chinese traditional medicine has gained a great deal of exposure through the Internet. Now there are a great many companies which sell herbal medicines over the Internet. Herbs, like all other organic substances are susceptible to all sorts of microbial infestations which can greatly compromise the quality of the plant and hence the product which you buy. Herbs infested with moulds, viruses or any of the many types of bacteria can loose most if not all of their beneficial medicinal properties and can even become dangerous to consume.

Herbs which are used in traditional Chinese medicine, like any other other cash crop are grown in fields or collected from the wild, they are then harvested, graded,cut to size,dehydrated, checked by quality control (hopefully), packed, stored in warehouses and finally shipped to the store where you buy them or sent directly to you if you buy via direct marketing routes. As you can see, plants used in traditional medicine go through many handling processes before they become the final product which you but. Every time the plant is handled, something of it’s original integrity and quality is lost. This is inevitable in any industry and each stage presents opportunities for cross contamination if the product is handled improperly. As with any product good manufacturing procedures (GMP) are an absolute necessity. Unfortunately, not all people who market traditional Chinese herbs are reputable manufacturers and great care must be taken in choosing which company to buy from.

Usually, the more high tech the facilities of a factory are, the higher product standards will be. Today, a number of Chinese companies are offering medicinal herbs in freeze dried form The advantages of freeze drying are that the raw materials used have to be of a high standard to ensure a stable end product. Secondly, freeze drying is a great way of preserving as many of the original qualities of the plant as possible. Thirdly, because freeze drying is a very quick process, there is no tome for bacterial or mould spores to form and oxidization is prevented. This means that from a food hygiene standpoint you are safeguarded against such micro organisms forming during usage. Fourthly, Freeze dried products deteriorate at a much slower rate than with other methods that are in use, among other things this means that the anti oxidizing properties of the plant(s) are preserved.

Freeze drying also permits the manufacturer to be very inventive during the manufacturing process. He can make blends that are intended to ensure that you the customer get a guaranteed strength of active ingredient and he can also blend different types of herbs to formulate products to make ready to use infusions for specific medical conditions. In addition, ingredients which make a product more palatable can also be added.

Some of these companies claim to have hundreds of blends in their product range which cover a great many medical requirements. If you intend to use traditional Chinese medicine I would strongly recommend that you investigate the possibilities offered by freeze dried technology.

Today’s post is a story that I heard from a colleague about a vegetable processing plant that became infected with salmonella and e. coli.

Please understand that this is a major international company and it is for this reason that I cannot disclose any names in the content of this article. This particular plant buys vegetables of all sorts directly from large farms and after grading, cleaning and sorting the vegetables are frozen and packed for the consumer and institutional markets.

The company in question works with just two or three trucking companies which bring the raw materials to the plant and deliver shipments of finished product to the local and foreign markets. Good relationships had been established with the trucking companies which included both the haulage companies and the factory itself helping each other out as much as possible as a matter of course. This factory had the best weigh bridge in the area and one of the favors that was performed on an ongoing basis was to weigh trucks of the said three companies even though the payload of the trucks had nothing to do with the business of the factory.

Complaints had been arriving at the factory’s quality control department stating that their products had tested positive for salmonella and e.coli. The factory checked all of their production lines to check that everything was working as it should and indeed no faults were found inside the factory itself.

A decision was taken to bring in an expert in the area of HACCP’s. and indeed it took him a mere five minutes to discover the source of the problem. Many different types of trucks were coming in to be weighed. Among them were trucks hauling the following cargoes: cages for chickens and turkeys being shipped from farms to slaughter houses, deep litter from dairy farms and poultry farms, various types of manure, and soil.

Trucks carrying these loads often waited for quite some time alongside trucks hauling vegetables for the factory itself. Dust and spray that inevitably flew from one truck to another was enough to cause the cross contamination of the vegetables with whatever the other truck was hauling.. This was a very basic and critical flaw in the work procedures and food hygiene standards of this particular factory. This situation was more than enough to cause this food hygiene crisis for this particular factory.

A decision was instantly taken to stop the weighbridge service to all trucks not carrying vegetables specifically for the plant. In this particular case, good intentions led to a very bad result.

OK, enough of the serious stuff for a while. Now it’s time for some frivolity in the form of cooking a couple of good chicken recipes. Here’s a two of my favorites. I hope you will like them too.

Remember that in order to keep your chicken bacteria free and to avoid all forms of food contamination please adhere to all the principles frood hygiene essentials stated throughout this blog.

Chicken Fillet Snitzels
This one’s so easy
Ok, Bascially you need to serve about 3-5 pieces per person to really sastisfy the apetite.
So work out how many pieces you need and then flatten the fillets gently between a plastic sheet (I prefer using a rolling pin for this).

Ingredients:
Chicken fillets.
3-4 eggs
1 cup of flour
bread crumbs
salt & pepper
sesame seeds.
Italian Herb mixture (optional).

We have already covered how to prepare the Fillets so I won’t go into that again. Next you will need 3 bowls or plates. In one you put the eggs which you will beat, in another the flour and in the last the bread crumbs, sesame and herbs. Add a little salt and pepper to the flour and to the crumbs.

Take each fillet individually and flour. Ater flouring dip into the egg. Shake off any excess liquid and place into the bread crumbs. Cover the fillet with the crumbs and press lightly. Remove onto a clean and dry tray or plate and repeat the precedure until all the fillets are breaded. If you have a lot of pieces you can divide the layers by using grease proof paper or baking paper.

To avoid the possibility of bacterial growth within the chicken or cross contamination between the eggs and the chicken keep the preparation time as short as possible. Twenty minutes should be ample time for this process and it will help to prevent the the devision of bacteria. Wile you are breading the shnitzels start to heat your oil. The time interval between finishing breading and frying should also be as brief as possible. It you can, serve straight from the frier, if not keep at a temperature of at least 65 degrees celsius until served. Any leftovers should be cooled and refrigerated to avoid bacterial contamination.

Now take a frying pan and add about 1/2cm. of cooking oil. Heat and fry the snitzels on both sides until golden brown. Serve with fries , rice or pasta. Add a little lemon and your favorite dip to the side of the plate. Don’t forget to eat plenty of fresh vegetable salad at least once a day.

Chicket Fillet Fajitas in fried Tortillas
My Personal Recipe
This recipe make a great main course, Brunch or between meal hunger stopper.

For this you will need about 5 fillets per portion.

Other Ingredients:
1 medium tomato (sliced) per 2 portions
1/2 green pepper per 2 portions(sliced)
1/2 medium sized onion per 2 portions(sliced)
Tomato puree
1-2 cloves of garlic
salt and pepper
Cumin
Chopped corriander
Corn starch
Cooking oil
Chilli Pepper or sweet chilli pepper sauce.
Tortillas

Equipment:
2 frying pans.

Before you start to fry rub the bottom of the pan with the garlic cloves. Slice the chicken fillets length ways and fry on a deep skillet. Add the onions and work in stir frying carefully for about 1 minute. Add peppers stir frying for about 1 minute also. Now add the tomatoes mixing gently until they begin to show signs of softening. Add salt & black pepper to taste. Put in about 1/2 teaspoon of cumin per 2 portions (reducing by 1/4 teaspoon for each 2 extra portions added). Add the chilli pepper or sweet chilli sauce. Add a little tomato puree to intensify the colour.

Now blend in the chopped corriander adding an ammount according to your own taste preference. Add a little sugar if the mixture needs it. Because you are going to fill the tortillas with the fajitas mixture it needs to be a little firm so mix a teaspoon of corn starch diluted in a little water into the fajitas to make the sauce a little less runny. Put the tortillas onto a table and fill them lenghwise with your fajitas mix. Roll them up gently making sure not to split them. Add a little beaten egg onto the lip of the tortilla and set aside. Now heat another frying pan with about 11/2 cm. of coking oil. Heat to a temperature of the oil 150 degrees centigrade Now add your tortillas to the oil carefully taking care not to get burned or to spill the content of the tortillas out. Fry until golden brown on both sides. Remove and place on kitchen paper to soak up the excess oil. Serve on lutuce with salza mexican rice or fries. Buon Apetite

At the bottom of this article you will find a full video presentation in six parts on the subject of food hygiene.

Most of us spend a great deal of attention to cases of food poisoning outside the home. Stories of food poisoning incidents hit the news and cause a great deal of anxiety and public interest. Someone once told me that food scares in the media are a bit like stories of air crashes. Although tragic and dramatic they do not amount to many deaths compared to road accidents. The same is true for incidences of food poisoning. Most instances of food poisoning do occur in the home environment.

However it is only natural to have this  concern about food hygiene from without the home because the food we buy and bring into the home environment comes from without. It is for precisely this reason that we are naturally tuned into collecting as much information as possible about where the best sources of food are and which places to avoid.

Even if we do manage to locate excellent food sources there will always be some bacteria present on it. We can never get completely away from this fact. Bacteria are everywhere. What we are looking for is sources that have not been exposed to unnecessary sources of contamination. Taking this fact into to account, the reason for promptly storing our food becomes clear. We need to keep it as fresh as possible.

Restaurants are involved solely in the preparation of food and if they work along strict hygienic guidelines the risk of food contamination is minimal. On the other hand, the home kitchen serves many functions. If only I had a dollar for the number of times I saw muddy football boots in the kitchen sink. The multi functionality of the home kitchen allows for many different possibilities for the cross contamination of food.

The kitchen is the place where any number of family mishaps are solved and family members come to the kitchen to clean themselves when really they should be using the bathroom. Kids may have been playing with their pet rabbits or the dog and the man of the house may have been unblocking a drain. In both of these instances the family members in question may go to take a drink from the fridge without properly washing and changing clothes. We all know this happens. Any kind of contaminant could spill onto food,

Another reason for food poisoning in the home is the direct and indirect interaction between the kitchen area and animal.s By animals I mean cats, dogs, mice, rats, birds, cockroaches, ants, flies, spiders, moths and in some countries maybe lizards and geckos. All animal species carry a huge variety of bacteria on their skin and in the feces and urine. Animals should not be allowed to jump onto kitchen work surfaces or eat from human utensils. If you are working with food avoid touching animals. Food should be kept in air tight food containers to stop insects and rodents from getting at it and work surfaces must be kept spotlessly clean at all times and sterilized with an anti bacterial spray such as Lysol spray.

Not everybody cleans their fruit and vegetables before storing them but I do like to wash it with a fruit and vegetable detergent. The soil upon your produce may come from many different areas of the world and it is better to clean it off than to have exotic strains of bacteria infecting your whole fridge. The special detergents for fruit and vegetables should also remove any insecticide residue from your fruit.

A major source of food poisoning in the home is failure to clean the fridge regularly and to check the freshness of the produce within it. Your fridge is a humid environment in which air circulates. This means that bacteria and molds can spread throughout your fridge in aerosol and contaminate many different items in a very short space of time. Always check your stock for food spoilage.

Preparing barbecue food is another common source of food poisoning in the home. People often leave food in containers in hot conditions while they are cooking. This gives bacteria an opportunity to grow. Grilling raw chicken takes a very long time until it is cooked through to the bone and bacteria have ample time to proliferate throughout the food. It is always best to precook chicken drumsticks, wings and chunks and to grill them just for the added taste of the grill. Thick hot dogs and burgers are also problematic for grilling on the barbecue. It takes a very long time for the heat to penetrate throughout and more often than not people eat only partially cooked food.

Thawing meat and fish. It is absolutely amazing when one learns just how few people understand how to thaw food. In the age when we constantly want things to be ready in a flash it seems time wasting to wait a few hours for meat to thaw. The solution is generally the microwave or to thaw in hot water. Both of this areas create hot spots on the surface of the meat where bacteria can develop. Meat should be defrosted in cold water but my personal advice is to plan three days ahead and defrost meat in your fridge at four degrees Celsius and in a closed container.

Ground meat and eggs are particularly sensitive items in the home kitchen. Ground meat is animal muscle whose surface area has been greatly increased. This increase of surface area is excellent for bacterial development. if other contaminants such as unclean spices or herbs are added to it as well as raw eggs, bacteria will be provided with the ideal environment. Raw egg is another perfect culture medium for bacteria. Ground meat should not be left out for long periods. It should be mixed with the other ingredients as quickly as possible and either cooked or re refrigerated until cooking. Personally I try not to exceed twenty minutes outside of refrigerated conditions.

Failure to follow manufacturers instructions is also an area in which much food poisoning in the home. Many pre made products are not suitable for baking, especially meat products which have been breaded but not pre fried.  Always read manufacturers instructions if you are using a product for the first time. Adhere to warnings stated on packaging.

The last area of concern that I want to talk about is the cleaning of eating and cooking utensils and equipment. Wash everything in very hot water and washing up liquid. Clean all grease from ovens and ranges promptly. Store equipment in clean cupboards and replace dish cloths and dish towels after each task. Use all kitchen equipment only for the function that it was intended. Personal hygiene is the function of the bathroom not the kitchen. Train your family on how to use the kitchen correctly and the risks of food poisoning in the home will be greatly reduced.

For many years my institutional kitchen operated in a very traditional way. We had a weekly menu and we would prepare each meal on and for the day it was intended. We would do essential preparations the day before after the day’s meal was closed. I was very proud of the variety and quality of the meals we put out. Very few five star hotels could match us for product quality, variety and taste.

One day an opportunity was presented to me. I was asked to prepare food for two other institutions the same size as my own. I knew that we were hard pressed to put out our own meal so how was I going to triple the work load. As things were my staff were going home at the end of their physical strength. It is a really hard days work to prepare food for one thousand five hundred people per day. I was going to have to think of a way of re organizing my whole operation without compromising quality.

One day I was reading a professional food industry magazine when I saw an advertisement for a new piece of equipment that looked, well, very much like an oven to be honest. The piece of equipment in question was called a blast chiller. The ad. claimed that the system could cool forty trays of food to twenty degrees in less than an hour. This claim intrigued me and so I contacted the company which was marketing the product.

After introductions the guy in the showroom said to me, “why waste time talking, lets go to see the product where it is being used every day”. I agreed at once, after all, actions speak louder than words.

After seeing the machine in action I knew that I was going to have a very personal relationship with a blast chiller. I knew that this one piece of equipment was the key to being able to triple my work load. The blast chiller was ordered and arrived one month later.

Without putting too much strain on the staff I had been making bigger batches of food and freezing them in my deep freeze. I knew that this was not ideal without my blast chiller but I had to have some inventory to be able to make the switch from cooking for 1500 people to cooking for over 4000 overnight.

I arranged a time for a staff meeting and told them how they would be working from then on. I told them that we would not be working as we had worked up to now. we would not be preparing meals for a daily deadline, instead we would be preparing stocks of food for the freezer. We would be reducing our daily task load from over eighteen Items per day to three of four. I told them that this would allow us to prepare bigger loads with fewer periods of transition from one task to another and we would be greatly reducing the risk of cross contamination by having fewer things flying around the kitchen.

What we would continue to prepare on a daily basis were soups, salads and things that couldn’t be frozen. All seemed interested in the new system but seemed a little puzzled. I asked them to trust me, they would not be working any harder and they would be given a wage raise for handling the extra volume.

Staff at the other two kitchens was cut to one third of what it previously was. It would be their job to receive the food the day before and to heat the meal up on the day. I bought small truck for transporting the food to the other kitchens. It was a truck with a cooler unit inside so that the food could be kept at a constant temperature of two degrees.

And so we started pumping our vast quantities of hot food which was rapidly cooled by the blast chiller and sent to one of the freezers within an two hours of coming out of the oven. To be able to do this operation successfully I took control of all the cooking trays and baking trays from the other kitchens We all used gastronorm trays so that did not present any problems. I did have to buy about 200 more but I had taken that into account and added the price to the cost of the food the others bought spread out over a two year period which I calculated to be the life expectancy of a cooking tray.

The system was working very well and the clients seemed very happy. Soon two more kitchens approached me to prepare food. I agreed to take on the extra work. I employed two more experienced members of staff and to tell you they truth we hardly felt the difference. I was now preparing food for upwards of seven thousand diners per day. The staff we now working very systematically, there was very little panic, everybody was smiling. What could be better.

My job was to formulate the recipes in such a way that diners would not feel that they were getting the same food all the time, to make sure all members of staff knew what they had to do, to make sure that the kitchen was cleaned before moving from an uncooked stage to a cooked stage and vise versa and to make sure that the end kitchens were handling and presenting the food correctly so that at each end dining room the presentation would look identical to all the other places.

And now I am going to tell you what the real key to running such a big operation is. Good technical staff. An operation like this needs  up keep and hitches do happen regularly. You need to be able to rely on your technical staff to solve problems quickly and professionally. I also aways have one oven more than I need. For this type of work I prefer to use a combi steamer oven. It is very versatile and is adaptable to many different cooking climates.

I can remember when I was about fourteen years old I went on a school trip to see a steel mill in Sheffield England. Three things impressed me on that trip. These three things were the noise, the heat and the rats. I could hardly believe my eyes. Not a bite of food in sight and yet rats were scurrying around not twenty yards away from where we were walking.

I can remember wondering why rats would bother about a steel mill. There was not a morsel of food in sight. It was not until fifteen years later that I would find the answer to that question.  Yet the fact remains that rats do infest many types of factories.

If the common denominator for rats establishing presence in factories and mills wasn’t food then what was it? In 1991 I began a course of practical Engineering in agriculture. It was during this course that I found out why rats infested many types of industrial plants. The reason is copper. Mice have trouble getting enough copper to be able to operate their immune systems and the missing link that enables them to do so is copper.

All industrial operations run on electricity and electricity runs through copper wires. Rats peel away the plastic coating on electric cables and lick the wire to get more copper and they do this obcessively. People who have worked in factories will know that from time to time they will hear an almighty bang. More often than not this bang is caused by a rat short circuting an electric cable. Needless to say that the rat is dead.

Why an I telling you this? Because one needs to understand that if rats had no reason to infest a food factory, they would still be there because of the copper wiring.

Food factories can be categorized into two main categories. Ones that process raw agricultural produce, plant or animal and ones that process food that has already been processed for industrial use.  In the first example produce is brought from the farm or co-operative sorting plant to the factory. Here the produce is tipped, washed, sorted and peeled or alternatively slaughtered, skinned, gutted and cleaned in the case of most animal produce.

In both cases the amount of dirt and contamination that is around at this intitial stage of the game is quite unbelievable and it is at this stage of the process that most rats are found. Only an ongoing, organized and regular cleaning regime can reduce the presence of rats and mice.

Once the produce has finished this init ial stage it is then passed to the next stage. Whatever the stage the amount of dirt should be very minimal compared to that of the first stage. As the product progresses towards packing the work environment should be almost sterile in comparison.

There are systems that analyze the risks and points at which one can reduce risks to food products. One such system is called HACCP. HACCP means hazard analysis and critical control points. In this system each hazard is defined and critical control points at which the level of the hazard can be reduced, eliminated or controlled are also defined and adopted.

There may well be one sequence of actions to control vermin and an entirely differnt sequence for the control of bacteria, for instance. It is the job of management to ensure that workerd are familiar with all the various sequences and to make sure that they are adopted and applied.

When this system is implemented in all of the factories various departments threats such as salmonella poisoning from rats is greatly reduced. Trouble can start when priorities and sequences are changed for one reason or another. The enemy of the HACCP system is cut backs. Cut backs in staff or cut backs in spending. Right now we are in the midst of a recession. In recession we can expect cut backs on more or less everything.

In plants where produce is immediately pumped through stainless steel pipes the opportunity for vermin to contaminate the produce is greatly lowered. Businesses such as bakeries may enocounter problems with rats at the end of the process rather than at the initial stages. For some reason mice  rats and cats do not seem to like white flour and prefer to wait until it has been transformed into bread products. Here pest control is particularly important because there is no process between contamination and the consumer that will kill the bacteria that have been transferred through cross contamination.  Nothing should be left unattended at this stage. Nothing should be but directly on the floor and nothingshould be put into plastic trays that have not been washed thoroughly in a proper industrial manner. To fail to be attentive to this points can cause indirect contamination via contact with vermin excretions.

The golden rule is to leave noting to chance. Always pre suppose that anything that can happen in theory will happen in practice.

They say, never judge a book by it’s cover. The same can be said about wine. I have one criteria that I use to judge a good wine and that is how good is it to drink?  Beverage quality and safety is not a science known only to the big wine producers.

I have bought so many expensive wines only to be completely and utterly disappointed that now I have absolutely no inhibitions about buying wine for one tenth of the price. Some small and quite obscure winerys are making very superior wines for a fraction of the price that you would pay for a Chateau Rothschild, for instance. To  find good cheaper wines I make a habit of going to my favorite wine merchants on days when he is having a wine tasting open day and make a point of tasting a good few of the cheaper wines as well as the more expensice ones. A good merchant, if he knows that you have an open mind, will give you tips about “little gems”  he has found. To be honest, usually it is enough to see the wine against the light to know it’s quality 

Generally speaking, about one third of the wines are not worth a second thought. One third are about the standard that you might expect from a three star restaurant and one third are really worth drinking. On deciding which wines I really like, I buy about two or three crates of assorted wines ranging from cabernet sauvignon to beaujolais.  I try do this about every couple of months.

I never let my dinner guests know that they are drinking bargain basement choices because all wine at my table is decantered. All that they ever know is that they are drinking a wine that is well worth drinking. It also gives me a sense of pride to know that I am helping lesser vineyards to raise their heads and take their true place among the established vineyards as truly good wine making professionals. The condition for this is that they continue to produce wines of a superior standard at competitive prices.

Some say that there is a lot of snobbery around the subject of wine drinking. I tend to agree with that to a degree because people who pay great sums for their wine, often have little or no idea of the wine making process. I have, in the past, tasted really expensive wines to which hydrochloric acid has been added in an attempt to cover up faults in the fermentation process. To those who know about wine, that is one of the most grievous cardinal sins possible to commit. Hydrochloric acid, when diluted to a concentration of five percent is synthetic vinegar. I don’t know about you but I most certainly do not want vinegar in my wine.

Adding hydrochloric acid is a technique that is sometimes used by winemakers who have fouled up the natural acid balance within the wine. By adding hydrochloric acid they are able to cover their mistakes to some degree and hopefully, those who are not experts in wine tasting will never know the difference.

If vineyards are faced with the eventuality of selling the majority of their years production as red wine vinegar they are tempted to use such inferior tactics. So, beware. It’s well worth Joining a good wine tasting course so that you’ll know the difference between good and bad wine and indeed, learn how to enjoy your wine much more.

Part of making really great wine has to do with maintaining correct hygiene conditions. We should always remember that the wine making process uses the yeast which is a naturally occuring micro-organism which grows on the skin of the grape. During the fermentation process the grape juice can pick up many forms of cross contamination in the form of various types of bacteria or undesirable forms of fungus which, if not prevent from entering the grape juice, will spoil or reduce the quality of the final wine. Cross contamination may well be the main cause of wine spoilage. All wineries are susceptible to  contamination precicely for the reason that they are processing a product which comes straight out of a fiels where it has been exposes to the surrounding environment for many months.

So, the message is that there is no absolute connection between the drinkability of wine and price. You will find many, many excellent wines from non label wine makers. Take a little time to discover those you like, enjoy the thrill of discovering priceless gems in the most unexpected places and save yourself a whole lot of money at the same time.
