Causes of Food Poisoning

Whilst Easter can be a truly enjoyable and joyous occasion, at the same time it can easily  turn sour due to various causes of food poisoning.

 

Bacterial Causes of Food Poisoning

While viruses cause some food poisoning cases, most result from bacterial contamination. Bacteria are tiny living structures that can only be seen with a microscope. Most bacteria are harmless but some can cause disease. If present in food, some of these disease-causing bacteria can cause food poisoning.

Where are these bacteria found and how do they get onto food? They are found everywhere; in soil and water as well as on people, animals and food.

Raw products, especially raw meats, poultry and fish, may contain dangerous bacteria. Bacteria on raw foods may then be transferred onto other food such as cooked or ready-to-eat foods during food preparation or storage. This is called cross-contamination.

People carry bacteria on and in their bodies, on their hands, face, nose and in their stomachs. Food handlers can transfer bacteria onto food if they don’t wash their hands after using the toilet or if they touch their faces or hair while preparing the food. Customers, like food handlers, can contaminate food by sneezing or touching food on display.

Pests such as insects, pets, birds and rodents can all carry bacteria and may contaminate any food they touch.

Dirty food premises harbour bacteria on dirt and food particles which can contaminate the food being prepared.

 

Cross-Contamination as a Cause of Food Poisoning

Cross-contamination – Food handlers who handle food incorrectly during preparation can spread bacteria and contaminate food directly by:

• Letting raw food touch cooked or ready-to-eat food.
• Letting blood or juices from raw food drip onto other food.

Food handlers may also spread bacteria and contaminate food indirectly by:

• Handling cooked or ready-to-eat food immediately after handling raw food, without washing hands.
• Using equipment such as knives, kitchen utensils and chopping boards for the preparation of cooked and ready-to-eat foods after preparing raw food, without cleaning the equipment.
• Placing cooked or ready-to-eat food on counter tops where raw food has been, without cleaning and disinfecting the work surface.
• Using the same dish cloth for different work surfaces or using dirty cloths.

You can find further useful information on preventing food poisoning and other food safety relevant information on the FSAI and SafeFood websites.

Prerequisite Programmes (PRPs)

All food handling businesses must have in place Prerequisite Programmes (PRPs). PRPs are good hygiene practices that are the basic conditions and activities necessary to maintain a hygienic environment. In addition, any food handling business must also consider maintenance of the cold chain and allergen control when putting PRPs in place.

 

Complying with the HACCP Requirements

Depending on the complexity of a food business operation, PRPs may be all that is needed to comply with the HACCP requirement. Furthermore, it may be possible to control hazards with PRPs alone. For example, if a food business carries out low-risk activities, all the hazards may be controlled by the Prerequisite Programmes (PRPs). In this case, there is no need for the application of a full food safety management system based on the principles of HACCP.

For more complex food businesses that involve the preparation, manufacturing or processing of food, PRPs are the basis of a Food Safety Management System (FSMS). The Food Safety Management System has to be based on the seven principles of HACCP. A PRPs can be implemented by:

1. following a recognised guide to good practice appropriate to a food business, or
2. developing procedures based on the principles of HACCP if required.

 

Hazards Controlled by Prerequisite Programmes (PRPs)

The majority of hazards can be controlled by PRPs. These can be the foundation for the HACCP based procedures to implement. Once PRPs are in place, your HACCP based procedures will focus on controlling the steps in a business. These are critical to ensure the preparation of safe food.

For more information on the various options for complying with the HACCP requirement see Guidance Note No. 11 Assessment of HACCP Compliance (Revision 2).

 

Prerequisites Include Where Appropriate

Prerequisite Programmes (PRPs) include the following:

• Premises and Structure – e.g.: Design and lay-out of workspace allowing for one-direction production flow. Sufficient lighting especially in food preparation and inspection areas. Suitable employee facilities. Hand-washing facilities;. External and interior construction of walls, floors, doors.
• Plant and Equipment – e.g. refrigeration services/systems; equipment fit for purpose operated in accordance with its instructions and accessible for cleaning.
• Technical Maintenance and Calibration.
• Cleaning and Sanitation.
• Zoning – e.g. physical separation of activities to prevent cross contamination with allergens or biological hazards. For example, harmful microorganisms from raw to cooked food.
• Procedures to Control and Prevent Physical and Chemical Contamination from the Production Environment – e.g. what to do in the case of breakage of glass, hard plastic etc.
• Supplier Control – e.g. supplier selection and agreement on specifications for raw materials, additives, processing aids, packaging material, food contact material.
• Services – e.g. water, ventilation, electricity, gas etc.
• Storage, Distribution and Transport (including temperature control).
• Waste Management.
• Pest Control – i.e. prevent entry of pests and implement suitable pest control programs.
• Personnel Hygiene and Fitness to Work – e.g. procedures for personnel suffering with gastro-intestinal infections, hepatitis, wounds or other relevant health problems.
• Training and Supervision – it is a legal requirement that staff who are involved in a food environment are trained and/or supervised commensurate with their work activity.
• Working instructions – i.e. provision of clear and simple work instructions which are visible or easily accessible.

Importance of Food Safety Training

Importance of food safety training in any food handling business is significant. Both consumers and those working in the hospitality and retail sectors are becoming more aware of the importance of food safety and implementation of HACCP based procedures. Part of the reason for this is when there is an incident of food poisoning, a large number of people may be affected resulting in serious legal issues, negative publicity and loss of livelihood. Owing to this, some businesses might be forced to close down.

 

Why is it Important to Train People in Safe Food Handling

It is the legal responsibility of everyone involved in the food sector to carry out their food-related activities in a hygienic manner. This applies to all food handling areas. In summary, these include food service, food wholesaling, food retailing and food processing. Each year there are 4000 – 5000 reported cases of food poisoning in the island of Ireland. However, the actual figure may be considerably higher than this. This is owing to many people with mild symptoms do not report these symptoms. To illustrate, the FSAI report from 2022 states that there were 4,058 complaints from consumers in 2022. About 1,200 were relating to unfit food and more than 1,100 each due to poor hygiene standards and suspected food poisoning. In other words, food poisoning concerns almost doubled from the 622 received in 2021.

Food poisoning, also called foodborne illness, is illness caused by eating contaminated food. Infectious organisms, including bacteria, viruses and parasites, or their toxins are the most common causes of food poisoning. Infectious organisms or their toxins can contaminate food at any point of processing or production.

To learn more about food poisoning and how to prevent it, the eLearn Safety has developed fully online food safety courses. These courses are designed to introduce participants to food safety and hygiene issues. All courses are based on the training criteria set down by the Food Safety Authority of Ireland’s Guide to Food Safety Training at appropriate level.

On completion of this food safety training course, participants will be able to understand their requirements under Irish food safety legislation as well as following best work practices.

 

Consequences of Poor Food Handling Practices

Food poisoning symptoms, which can start within hours of eating contaminated food, often include nausea, vomiting or diarrhea. Most often, food poisoning is mild and resolves without treatment. However, some people need to go to the hospital. In addition, food poisoning is especially serious and potentially life-threatening for young children, pregnant women and their fetuses, older adults, and people with weakened immune systems.

In any case, to prevent food poisoning, these essential principles should be adhered to:

• Wash your hands, utensils and food surfaces often.
• Keep raw foods separate from ready-to-eat foods.
• Cook foods to a safe temperature.
• Refrigerate or freeze perishable foods promptly.
• Defrost food safely.
• If in doubt, throw it out.

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!

Storing Food After Delivery

Storing food after delivery is very important when food safety is considered and the food should be stored as quickly as it can be put away. For instance, in a previous eLearn Safety blog post Receiving Food Delivery from 19th January 2024 we talked about the importance of proper and planned handling of food deliveries. Most importantly, it is very important to note that once the food is accepted from delivery operators it should be unpacked from the outside packaging before storage. In addition, frozen foods should always be stored first. It is extremely important to remember that raw meat and ready-to-eat foods should be handled and stored separately. All food handling staff should be competent and trained in safe food handling. An easy and convenient way to achieve this is by taking one of eLearn Safety fully online Food Safety courses.

 

Plan for Storing Food After Delivery

Never tightly pack food in storage areas. For instance, food should always be kept at least 15cm above the floor and at least 5cm away from the walls. This is because it will make cleaning and pest inspections easier.

In addition, keep records of all food temperatures. If you observe high temperatures, report this immediately to the Supervisor/Manager. This can be the result of a delay in storing food, allowing it to warm up to room temperature. Such delays can be avoided by having allocated time slots for staff to store food correctly.

 

Contamination is Dangerous

Food contamination is very dangerous! You must remember to:

• Keep raw meats in a separate refrigerator or on the bottom shelf. This is to avoid contaminating anything below.
• Clean soil from vegetables before storage as soil can contain dangerous bacteria.
• Check all seals of fridge and freezer doors are working properly and are clean. Fridges and freezers should be checked every day and detailed, stringent temperature records maintained. If you are using a walk-in freezer – always make sure that the door is closed properly behind you.

 

Stock Rotation

Stock rotation is important when we talk about storing food after delivery. Therefore, you should always practice a FIFO system (First In First Out). In addition, you should label each item so that anyone who would check for these items knows when it was delivered and its shelf life. For instance, never sell food that has passed its Use-By date and make sure that all the correct storage requirements are followed.

For additional information about Use-By and Best-Before dates please check eLearn Safety blog entry Shelf-life of Food Products from 10th March 2023. In addition, you might find some very useful information on Teagasc website and their page Shelf Life of Food Products from 9th January 2022.

 

Basic Storage Rules

Always remember to:

• Store all frozen food at below -18°.
• Store all fresh food at below 5°.
• Store dry goods quickly.
• Keep fridge and/or freezer doors open for the shortest time possible.
• Immediately report a fridge or freezer malfunction. A breakdown can be an expensive and serious food safety hazard.
