Spores and toxins in food can be a cause of a serious food poisoning. Spores are a bacteria’s survival package. Some bacteria when faced with adverse conditions such as rising temperatures will form a survival spore. A spore has a protective shell which can withstand higher temperatures than those reached in cooking.
Water boils at 100°C. This means that most of cooking will be only a little hotter. However, spores can survive temperatures of up to 120°C. When the heat returns to room temperature, the spore opens. Once this happens, the bacteria starts growing to form another colony. This is why hot holding at temperatures above 63°C prevents spores become active, whereas rapid cooling does not give a chance to spores to open.
Two common spore-forming bacteria are Clostridium perfringens and Bacillus cereus. Some foods such as red kidney beans simply need to be cooked to break down the toxins and render them harmless.
Some toxins are produced by careless defrosting food (e.g. scombrotoxin). Toxins are poisons that are produced by bacteria and plants. Toxins can be deadly, such as that produced by Clostridium botulinum. The verocytotoxin produced by E. coli and its relatives causes damages to kidneys and the intestine. This may result in death, especially in the elderly and the very young. Seafood can also contain dangerous toxins. One of these toxins can cause paralytic shellfish poisoning (PSP). Paralytic shellfish poisoning as the name suggests, causes paralysis. Shellfish such as mussels feed on smaller animals that produce this toxin. In large groups these animals can be seen as a red bloom known as ‘red tide’. There are monitoring systems such as satellite images, that warn where and when shellfish must not be harvested.
Plants can contain toxins. Some toxins are produced by moulds. These toxins include aflatoxin, which can seriously harm the liver. Such toxins are found in cereals and dried fruits that have been poorly stored. All these examples demonstrate the importance of always obtaining quality food from reputable suppliers.

Hand washing for food handlers is an essential aspect of cleanliness and hygiene. When it comes to food hazards, food handlers are potentially one of the biggest risks in terms of food safety. However, to extend this, hand washing is not important only in a food preparing environment, but in a domestic one as well.
According to a research by BMC Public Health, Denmark tops the ranking when hand hygiene of consumers is looked into. According to a study Hand hygiene practices during meal preparation—a ranking among ten European countries, the ranking is as follows: Denmark, Greece, Norway, Romania, Hungary, Germany, UK, Portugal, France, and Spain. However, the overall conclusion of the study was that the hand washing is often done incorrectly by skipping areas of hand when washing, or washing one’s hands not long enough. Unfortunately, this is also true when handling risky food such as raw chicken. According to the study, the young families and pregnant women are most likely to neglect a proper hand washing technique. On the other hand, the elderly individuals generally do not wash their hands when required.
Most likely, the single most important activity in the food preparation area is proper hand washing. Hands are used for everything – scratching your nose, touching your phone, keys, emptying bins, handling cash, and finally touching the food that is being prepared. It is incredibly easy to cross-contaminate food just by using unwashed hands.
Food workers have a moral and legal responsibility to ensure that they do not contaminate food. One of the characteristics of a good food worker is a positive attitude towards hygiene and a willingness to help maintain a high standard at the workplace. Hand washing is at the top of hygiene importance.
Food hygiene legislation places a legal responsibility on food workers, proprietors and visitors to maintain a high degree of personal cleanliness.
Keep the body clean – Food workers should wash or shower daily to remove the layers of dirt, dead skin, sweat and bacteria that build up on the body which can be passed onto food.
The law requires that:

Hands can never be washed too often, but they can be washed not often enough. This is especially important when hand washing for food handlers is in question. Always aim to wash your hands:
The main point to take is – Wash Your Hands regularly!
Hands must be washed at a wash hand basin supplied with running hot and cold water. Liquid bacterial soap and an approved means of hand drying should be used. The hands, front and back and the gap between the thumb and forefinger must be washed using a rubbing action. It is not satisfactory to run fingers under the tap and then to dry hands on uniforms.
To learn more watch the below video prepared by SafeFood.net titled How to wash your hands properly.
Hand washing for food handlers is extremely important as correct hand washing will remove bacteria such as E. Coli and salmonella. Bacteria on the hands have an ideal environment, They have food, moisture and a temperature of around 37°C allowing speedy reproduction and a higher risk of infection. This is why hands must be kept meticulously clean at all times.

Pest Control in any food handling premises is an extremely important process. Food pests are a source of food poisoning organisms. When one talks about pests, the majority of people think of rats, mice, birds, flies, etc. Whilst they are a major food safety hazard from the Pest Control perspective, domestic pets are also a significant hazard. By being pets they are often not considered a danger. However, domestic pets should never be allowed into food handling areas. They carry bacteria in their fur, feathers, skin, saliva and intestines. Stroking or fussing cats, dogs or other pets will contaminate food handlers.
A food pest is an organism that lives on or in human food. Pests can contaminate food with bacteria and disease, but they can also cause physical contamination from droppings, urine, fur, feathers and even dead bodies.
Pest problems can result in lost revenue through damaged stock, gaining a bad reputation and in some cases legal action against the business.
According to the FSAI News Article from 13th July 2023, 12 Enforcement Orders served on food businesses in June. Some of the reasons for the Enforcement Orders in June include: a history of rodent activity with droppings found near fruit juice intended for children; open, ready-to-eat foods such as fresh lettuce suspected as having come into contact with rodents, with a likely risk of Salmonella; heavy cockroach activity in the kitchen, with dozens of live cockroaches spotted moving around food preparation areas, on the walls, floors, fridges, and inside food storage containers; a lack of adequate traceability systems and procedures for all products, undermining consumer safety; a failure to maintain the cold chain with insufficient fridge space to safely store high risk foods such as cooked rice and pasta; rodent droppings noted in the service area and near food storage; risk of cross contamination with ready-to-eat food such as smoked salmon stored next to raw food such as chicken and pork chops; and inadequate ventilation throughout the premises, evident by the large build-up of mould on the walls, ceilings and external doors.
Food premises often provide ideal conditions for pests as they provide food, warmth, shelter and water. It is therefore important to make sure premises are properly maintained to avoid pest infestation.
It should be part of any food handling business’ routine to check for signs of pest infestation. If any kind of pests activity is noticed and reported, this has to be dealt with immediately. It may be necessary to seek professional help from a pest control contractor or a local authority. It is always preferable to treat the problem by removing the pest. This avoids the possibility of it dying inside the food area and causing further contamination. Extreme care should be taken if chemical controls are to be used.
Prevention is better than cure and good housekeeping can play an important role in pest prevention. Some of the steps towards preventing pest infestation are:
All pests damaged goods should be removed and destroyed.
Common food pests that can be found in almost any, rural or urban setting are:
Food premises can be (and have been as mentioned above) closed down as a direct result of pest infestation. Pest problems should never be ignored!
Please remember – it is a legal requirement that staff who are involved in a food environment are trained and/or supervised commensurate with their work activity!

Proper food storage and deliveries play an important role in ensuring that the food remains safe to eat. Existing food businesses which intend to start delivering food orders need to consider any new or different risks posed by this change in operation. They should adapt their Food Safety Management System to make sure food placed on the market remains safe to eat. Businesses that already deliver food, directly to the customer or to another business, must ensure uninterrupted safe food handling practices.
It is important that food is purchased from reliable suppliers. ‘Due diligence‘ demands that care be taken on purchase handover. When food is delivered, a person responsible for the receipt of the food should check:
Always and without any doubt reject any food that you are not happy with and return it to the supplier! Always make sure that the transfer time after purchase of frozen or chilled foods is as short as possible, preferably in cool bags or boxes and that the food is stored in the refrigerator or freezer in the shortest possible time. Remember:
Food is spoiled when it is unfit for human consumption. The main causes of food spoilage are usually the following:
Most food packages are labelled with a ‘Use By‘ or ‘Best Before‘ date. It is an offence to serve food that has exceeded its use by date. Such food should be discarded or clearly marked ‘Unfit for Human Consumption‘. ‘Best Before‘ dates are often an indication that the food will be at its premium quality if stored correctly until that date.
Not all food must be kept refrigerated or heated. Some food can be kept in dry stores. However, many dried or dehydrated foods such as milk powder, powdered eggs, etc. will allow bacterial growth if they become moist. It is therefore essential these foods are stored in a dry place and are used immediately after preparation. All dry foods, including flour, biscuits, etc., will remain safe whilst dry.
Dry stores key points:
All food should be stored in date order and the First In First Out (FIFO) rule followed and observed. To help with stock rotation:
There are other food safety hazard points associated with food delivery and storage. Safefood lists a number of additional hazards that are associated with the food storage and deliveries. These can be read in their Food Delivery & Storage article.
