Food Hygiene: User Journey
This lesson is designed to introduce students to food safety and hygiene. Students will learn about the journey of food from shop to plate and how there are critical points where food hygiene and safety are key. Poor food hygiene can lead to cross-contamination and foodborne illness.
All students will:
- To understand that there are harmful microbes in food that can cause food poisoning, where they can be found, and risks and consequences of food poisoning
- To understand cross-contamination and how it occurs and develop and normalise skills for good hand and food hygiene and preparation in everyday life to remain in good health
- To understand the chain of infection and critical points for food hygiene
Food can contain useful and harmful microbes, as well as those associated with food spoilage. It is harmful microbes that can be associated with foodborne illness or ‘food poisoning’. The top five foodborne microbes in Europe account for about 70% of the health burdens related to foodborne illness and these include; Norovirus, Toxoplasma gondii, Campylobacter jejuni, Campylobacter coli. Salmonella enterica, and Listeria monocytogenes. Other microbes such as Bacillus cereus and Escherichia coli have also been associated with serious cases of foodborne illness.
These microbes can be found in raw meats, in eggs without a British Lion mark or equivalent quality marking outside of the UK, some dairy products, on the surface of fruits and vegetables, in dried food like pasta and rice or in ready to eat foods such as sandwiches and desserts.
Symptoms can include diarrhoea, stomach cramps, fever and vomiting and some foodborne illness may even result in death – though this is rare. The symptoms of foodborne illness usually start within a few days of eating the food that caused the infection and can usually be treated at home with rest and fluids.
Not all microbes associated with food are harmful. Useful microbes can be used to make food and drink, e.g., the yeast Saccharomyces cerevisae is used to make bread and beer. Lactobacilli bacteria are used in yoghurt and cheese making.
There are important steps you can take to prevent foodborne illness and spoilage that apply at all stages in the journey of food, from the shop to our plates:
- Keep clean: maintaining hand and surface hygiene is the best way for avoiding foodborne microbes entering our food
- Maintain the cold chain: keeping food in the fridge or freezer slows the growth of bacteria but does not stop it. Minimise the time food spends outside of the fridge or freezer
- Prevent cross-contamination: preventing harmful microbes found on food from spreading to other foods (for example via our hands or kitchen utensils) and causing illness when those foods are eaten
- Cook food such as meat thoroughly
- Follow the advice on labels: labels placed on foods are used to determine when it is safe to eat the food, or when the quality of the food is at its best
- Food Journey animation to introduce students to the concept of cross-contamination and the principles of good food hygiene
- User journey worksheet which can be completed individually, in groups, or as a classroom discussion activity
'Distractions in the kitchen' activity. This could open a discussion about the impact of distractions on food safety (Optional).
