Food Hygiene Essentials

Human beings have always needed packaging in one form or another. Some of the earliest types of packaging are still around today, for example reed baskets. Initially all packaging was made from natural materials, because it had to be.

Woven bags and wooden boxes were among the first. As more materials were developed and processed they too became of use as packaging.

During the 19th century, and as a result of the industrial revolution, packaging became far more advanced. Tin cans and the first cardboard boxes emerged. Later still, in the early 20th century, plastics and aluminium were incorporated into packaging, around the same time we were becoming more and more aware of food safety and food hygiene.

We have made huge advances in both packaging and food safety.

Today packaging is a highly scientific field, it also requires technological and artistic understanding, as well as in-depth product knowledge. There are hundreds of high profile careers within the industry, including ‘Packaging Engineering’. Subjects studied for this qualification are varied, basic engineering, basic science, and business, food safety, recycling, even robotics! It is an industry that is always advancing.

Some functions of packaging;

Containment of product
Protection of product (physically and hygienically)
Product control- e.g. tamper evident opening
Product information
Marketing and branding of product/retailer
Provides controlled sized portions/amounts of product

As our global awareness of the environment increases, our priorities and requirements of what packaging should be changes. A now commonly used phrase – ‘Reduce, Re-use, Recycle’ is of great importance where packaging is concerned. Sustainable packaging is an area in which experts are particularly keen to develop.

Packaging has become more than just a means of easily transporting or containing products and is currently categorised into packaging types;

Primary – usually in direct contact with product e.g. brown kraft paper bags
Secondary- contains primary packaging and product, e.g. a multi-pack of crisp packets
Tertiary- involves warehouse storage and transport of bulk products, e.g. pallets

Within these types of packaging are more type-specific fields, e.g. drugs or food.

Food packaging is a specialist subject within the packaging industry, and works closely with the U.K’s governing body for all food legislation and safety, ‘The UK Food Standards Agency’. Food safety entails scientifically researched rulings on all aspects of food to prevent food borne illnesses.

We all expect there to be specific rules and guidelines in place for Dental Surgery Assistants, or Hospital Nurses to prevent illness or disease through the spreading of bacteria and viruses, but would you expect such rules to be in place for food? Well they are!

The UK Food Standards Agency provides the food industry and the general public with well researched, easy to access information regarding food and food safety, it also enforces laws on, for example, required standards on food packaging materials.

A great deal of scientific research is undertaken to ensure all materials which contact food at any stage of its handling is safe, from food containers, to the ink used in food product labelling. It is their responsibility to ensure the public is kept safe from harmful chemicals through related materials. There are specific rules in place for specific materials, plastics, for example have a whole list of laws for themselves.

On the UK Food Standards Agency website there are notes on ‘Guidance on the Plastic Materials and Articles in Contact with Food (England) Regulations 2009, available for associated businesses to read. It also provides information on which legal body represents particular materials, so you know who you are legally required to obey.

In 2004 a new European Regulation was introduced regarding food contact materials, and the UK Food Standards Agency was responsible for representing our countries interests. Their primary goal was ensuring UK citizens are still kept safe from risk of harmful chemicals in food contact materials when on holiday in Europe. This is also available to read on their website.

The development, research, and governance of food packaging both for supermarket food and for home-prepared food is vital not only for our convenience, but also for our safety. The next time you put your sandwiches into ‘food safe polythene bags’ or your children come home with sweets in’ candy stripe paper bags’ think how many experts have made it safe enough for us all to use.

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.

The world continues to watch in despair as the honey industry continues to tale huge knocks. In recent weeks vast quantities of honey imported from China to the USA were stopped at US ports after checks showed that the honey contained low to moderate quantities of Chloramphenicol, an antibiotic which is not approved for ingestion.

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.

My friend is a very experienced food technologist and he should have known better than to do what I am about to tell you. During a visit to his doctor he was advised to add more fiber to his diet. No being a great eater of vegetables my friend decided to find a more creative solution to adding fiber to his diet.

Food spoilage is really nothing more than a natural deterioration of organic matter. Everything in nature has to be broken down so that it can once again become part of the composition of soil. All of the various natural processes that participate in the spoilage of organic material are ultimately directed toward this aim.

Pseudomonas bacteria are a genus of bacteria which exist widely in the environment. They are gram negative, rod shaped, non spore forming, motile, flagellated aerobes. Pseudomonas aeruginosea, probably the most well know of all pseudomonas strains, is an opportunistic pathogen that has the capability of adapting to many niches. It can infect animals and humans alike and can cross the species barrier and for this reason it is considered a potentially zoonotic pathogen. This type of bacteria is immune to many types of bacteria because it has within it’s cell wall a mechanism known as an efflux pump which pumps antibiotics back out of the cell before they have had time to take effect. It is the second most common bacterial contaminant in hospitals and it is known to be paticularly malicious in burn units where it prevents the regeneration of healthy tissue. Bacteria of the pseudomonas family are grown on blood agar which turns from a blood red color to a marine blue/green hue. It also gives off a quite pleasant slightly minty smell.

One form of Pseudomonas pathogen causes a highly contageous disease in horses which is also highly infectious to humans. The disease in horses is know as glanders because it affects the glands in and around the throat and jaws of the horse. This disease was common when colonial forces shipped large quantities of horses to places like Africa, the Middle East and the Far East. Now, this disease is more rarer. The scientific name of this pathogen is Pseudomonas Mallei and it is registered as one of the possible bacterial strains that could be used in bacterial warefare together with Clostridium Botolinum and Anthrax.

Other forms of Pseudonas bacteria are known to cause spoilage in food at low temperatures. These psicrophilic Pseudomonas strains include: P. fragi which causes spoilage of dairy products , P. taetrolens which causes mustiness in eggs and P. mudicolens, and P. lundensis, which causes spoilage of milk, cheese, meat, and fish.

The term spoilage is used in food hygiene for a condition by which the food takes on an unpleasant texture, color change smell taste. This does not mean that the food has necessarily become a serious health risk in the same way as if meat were infected with e.coli or salmonella, for instance, but at the same time it is definitely not advisable to eat spoiled food. It means that the food has been infected with bacteria which cause the physical nature of the food to change. For instance, meat may become slimy to the feel or the outer lawyer of certain foods may become pulpy, it may also smell slightly sour and change color. This happens to food which has been stored in refrigerated conditions for long periods of time in places which have not been properly cleaned with anti bacterial disinfectants. I often see this condition in places such as deli counters where meat is sliced in front of the customer.

However a little slime on meat, such as with cured pastrami in particular and with other types of processed meats is not always a sign of spoilage. It may well be due to a reaction between the protein of the meat, the curing chemicals and the air. Many manufacturers now use preservatives to prevent such spoilage. In addition, the reaction of the preservative with the air and other factors within the meat can cause the color of the product to change slightly as well. The color of the may become slightly irridescent or take on a greenish hue. If the meat smells even the slightest bit sour, feels or looks slimy or has a bad color refuse to accept it.

Spoiled food such as cured meats meat can cause stomach discomfort, diarrhea, vomiting or mild allergic symptoms in some people and may even become more serious in people whose immune system is compromised. Remember this central rule of food hygiene, “When in doubt throw it out”.

Fish products are particularly susceptible to spoilage and it can be very difficult to guess from a casual inspection if the deterioration of the fish is due to spoilage bacteria such as the psicrophilic pseudonmonas species stated above or if the cause is due to more dangerous, pathogenic forms of bacteria. If fish looks even slightly slimy, discolored or smells in the least sour don’t buy it or if it has turned bad in your fridge throw it out and clean you fridge thoroughly with disinfectant. (A tactic used by many fresh fish mungers to hide the tell tale smell of fish which has started to show signs of going off is to constantly pour sea water over it. Watch out for this trick. If you are not sure if you are smelling the actual fish or sea water, don’t buy the fish). Most importantly, keep all fish products in closed containers to avoid cross contamination with of by other food products in your fridge.

The same goes for eggs milk and cheese, if you distinguish any changes in color texture or smell, don’t take any risks, better to throw out and buy fresh. To lower the risk being sold spoiled or food which is about to spoil, buy only from supermarkets and stores which are very busy and have a high turnover of merchandise, particularly in the deli sections. Don’t be embarrassed to inspect what you buy, you are paying for fresh and healthy food and the decision to take what is on offer or not is entirely your own. The customer is always right. If you notice that the food you buy goes off quickly and you know that a). your fridge is clean and b). the temperature of the fridge is as it should be then take the food back to the store with your receipt and demand a refund or a fresh replacement. If the problem continues report your findings to your local authority for food hygiene.

A few weeks ago a leading Israeli fruit juice manufacturing plant had several hundred tons of water melon concentrate condemned by the ministry of heath on the pretext that there were unacceptable contaminants within the juice.

The concentrate in question was destined for use on the home market where it is used by the ice cream and iced lollie factories to manufacture a popular range of water melon flavored products. This set back has put additional pressure on a market sector which is already struggling to survive the current market recession.

Israel has suffered several consecutive years of very low rainfall. The sea of Galilee which is the major fresh water reservoir for Israel and it’s neighbours has reached dangerously low levels and as a result of this crisis water prices have risen several fold. As a result of this new state of affairs the profit margins in which vegetable and fruit growers operate have been cut even further and it is really uncertain from year to year if it will be worth growing anything at all.

The jordan valley which enjoys a milder winter than many other parts of Israel is famous for producing early fruit and vegetable harvests both for the home and export markets.

Seemingly, some of the areas water melon growers took it upon themselves to irrigate this years water melon harvest that was intended for industry with grey water instead od fresh water. The logic behind this decision being that grey water does not contain more contaminants than those already presant in ordinary soil.

What is not clear is if the water used for irrigation was indeed just grey water or if the suppliers of the grey water added certain quantities of first stage black water filtrate to the grey water that was being supplied to the farmers. It is also possible that the farmers used grey water for the initial stages of germination and consequent stages before the development of the water melon itself, switching over to fresh water once the melon began to develop. In any case, whatever the sequence of events was, contaminants entered the melons.

Samples of the water melon concentrate were tested both for chemical and microbial contaminants and found to test positive for both categories of contaminates within the concentrate. the concentrate was deemed to be a risk to public health and presented a food hygiene problem. The water melon concentrate was condemned and will not be used to make the iced products that it was intended to make.

The case is being looked into more closely by the public prosecutors office and charges are expected to be issued to those responsible for taking these regretable discisions to used contaminated water for growing water melons.

He violated the trust placed in him when he was awarded a licence to run a food business. He attempted to make cynical use of his religious beliefs to justify his actions and discriminated against the inspectors when he called them non believers. His crass, lazy and obstinate attitude worked against him and he got his just deserves.
