When going to university or living away from home for the first time, you may be taking on more responsibility for deciding the food you eat, and how you prepare it, than before.
Now that you may be cooking more, it’s important to understand the basics of food hygiene so that you can stay safe and not let food poisoning affect your experience.
Use this student guide to explore the basics of food hygiene and safety to protect yourself and those around you.
Avoiding food poisoning at home
Food in your fridge may contain harmful bacteria and if stored for too long, at the wrong temperature, or not cooked properly, can cause food poisoning. Harmful bacteria can equally spread on unclean surfaces around your kitchen.
Avoid food poisoning at home by understanding food safety and embedding good food hygiene practices in your home.
Understanding use-by and best before dates
We know that when budgets are tight, food hygiene can slip. It might be tempting to eat food that is beyond the use-by date, but doing so puts you at increased risk of food poisoning.
It’s important to know the difference between a use-by date and a best before date so that you can make safe food choices. Always check the label to make sure your food is in date and safe to eat.
A use-by date on food is about safety. This is the most important date to remember. You can eat food until and on the use-by date but not after. You will see use-by dates on food that goes off quickly, such as meat products or ready-to-eat salads.
Food can look and smell fine even after its use-by date, but that doesn't mean it's safe to eat. It could still make you ill. You cannot see, smell or taste the bacteria that cause food poisoning so should never trust the sniff test.
The best before date is about quality, not safety. The food will be safe to eat after this date but may not be at its best. Its flavour and texture might not be as good.
If your food is close to the use-by date, you can help keep the food for longer by freezing it. A freezer acts as a pause button, meaning food in a freezer won't deteriorate and most bacteria cannot grow in it. You can freeze pre-packaged food right up to the day of the use-by date.
Food hygiene in a shared fridge
We realise that at university, and when living away from home for the first time, you may only have access to one shelf in a shared fridge.
We ordinarily recommend that you store raw meat, fish and shellfish on the bottom shelf of your fridge. This is to reduce the risk of cross-contamination with other ready-to-eat foods.
When sharing a fridge, avoid ready-to-eat food being cross-contaminated by raw meat and fish on the same shelf, by not storing opened packets of meat, fish or shellfish. Instead put the food in separate containers. Use sealed or waterproof containers to avoid leakages and limit the spread of harmful bacteria.
You should also avoid putting open tin cans in the fridge as the food inside may experience bacterial growth and develop a metallic taste. Follow manufacturers instructions or place the contents in an appropriate storage container before refrigerating.
Remember to check the contents in the fridge regularly so that any foods past their use-by dates are disposed of quickly.
Cooking your food properly
Cooking your food at the right temperature and for the correct length of time will ensure that any harmful bacteria are killed.
It’s important that you always check the advice on food packaging and follow the cooking instructions provided until the food is steaming hot.
Some products such as breaded chicken, chicken goujons and other meat products, are often assumed to be ready to eat, but can actually contain raw meat such as chicken. Such products are not ready to eat, unless stated on the packaging. Always check the cooking instructions and heat appropriately.
Try not to cook different foods at the same time in the oven if they require different temperatures, as this may lead to some food not being fully cooked. If you do cook different items at the same time, always follow the longest cooking time on the food instructions.
Did you know?
You should not wash raw chicken. Washing raw chicken and other meat can spread campylobacter by splashing it onto hands, work surfaces, clothing and cooking equipment.

To reduce the risk of spreading harmful bacteria you should regularly wash your hands.
You should wash your hands:
- before preparing food
- before handling cooked or ready to eat food
- after preparing raw foods, or handling its packaging
- after handling waste
- after cleaning surfaces
- after eating and drinking
- after sneezing, touching pets or going to the toilet.
Where possible you should wash your hands with warm soapy water for at least 20 seconds.
Making the most of your food
When budgets are tight, avoiding unnecessary food waste can be a really useful way to make your money go further. This does not mean having to compromise on food safety.
Love Food Hate Waste have some useful tips and advice on how to make your food go further and reduce waste.
Reusing and reinventing your leftovers is a great way to make the most of your food. Cool and cover your leftovers, and put them in a fridge or freezer within one to two hours.
You can split leftovers into smaller portions so that they cool quicker. This can also help portion control and planning for future meals.
If you store your leftovers in a fridge, rather than freezing, they should be eaten within two days.
Did you know?
Leftover foods such as rice should be cooled as quickly as possible, ideally within one hour.
They should be kept in the fridge for no more than one day. Cooked rice should not be reheated more than once.
You can use previously cooked and frozen meat to make a new meal, once it has fully defrosted. You should eat the new meal within 24 hours.
For safety and to reduce waste, only take out of the freezer what you intend to use within 24 hours of defrosting.
Freezing and defrosting your food
A freezer acts as a pause button. This means food in a freezer won't deteriorate and most bacteria cannot grow in it. You can freeze pre-packaged food right up to the use-by date.
Leftovers and homemade foods should be frozen as soon as possible. Make sure any warm dishes are cooled before putting them in your freezer. Freezing food into individual portions will make them easier to defrost and you will use only what you need.
When you take your food out of the freezer, it's important to defrost it safely before cooking or eating it. Don't defrost food at room temperature. Ideally, food should be defrosted fully in the fridge in a waterproof container. If this isn't possible, use a microwave on the defrost setting directly before cooking.
Make sure your food is fully defrosted before cooking. Partially defrosted food may not cook evenly, meaning that harmful bacteria could survive the cooking process. Once food has been defrosted, eat it within 24 hours.
Did you know?
You can freeze rice, eggs, potatoes, fruit and all kinds of food.

A cost effective way to manage your food and budget can be to bulk cook one dish and separate it out into different containers to eat throughout the week.
When bulk cooking, remember to cool and cover your food, and put them in a fridge or freezer within one to two hours. Do not leave food in the pan for extended periods of time as bacteria may grow.
Food that has been adequately cooled down within 1-2 hours should be stored in the fridge and consumed within two days. If you cook more portions than you can eat in two days, freeze any extra portions.
Bulk cooking can be a great way to make your budget go further, but avoid preparing certain foods, such as rice, in advance. You can get food poisoning from eating reheated rice.
Consume cooked rice within 24 hours of cooking. When you reheat any rice, always check the dish is steaming hot all the way through.
Food past its best before date
The best before date on a food label is about quality, not safety.
When shopping, look for foods that have longer dates on the label so you can be confident that you will use the food.
You can still eat food safely for a period after the best before date, but never beyond the use-by date.
Keeping your kitchen clean
Effective cleaning and sanitation helps remove bacteria and stops harmful bacteria and viruses from spreading onto food.
Establishing a cleaning rota amongst your housemates and ensuring that there are a sufficient amount of cleaning products available, can help to encourage good cleaning practices in a shared kitchen.
Avoiding cross-contamination on surfaces and chopping boards
It’s important to keep all surfaces, chopping boards, utensils and dishes clean before preparing food. This is to avoid cross-contamination. This is particularly important between tasks and when preparing raw meat.
You are removing harmful bacteria by cleaning with warm, soapy water or by using disinfectant cleaning products and following the instructions on the label.
Cleaning with washing up liquid does not kill the bacteria, but removes them into the waste water. Because of this, change the water you wash utensils in regularly.
While it is possible to clean with cold water, using warm water will ensure that the washing up liquid lathers up properly. It is important that it lathers so it can be more effective at removing the bacteria.
Cleaning high-touch items
In every kitchen there are high-touch items that regularly come into contact with dirty surfaces, but which may be overlooked when cleaning. These can pose an increased risk of cross-contamination.
It is important to wash or change dish cloths, tea towels, sponges and oven gloves regularly. If you wash them, let them dry before you use them again as dirty, damp cloths allow bacteria to breed.
Did you know?
Research has shown that phones, tablets and other devices can become really dirty and are easily contaminated with a lot of germs.
Make sure that you regularly clean and sanitize your phone, especially when you are using it to read recipes or help you cook.
To avoid touching the screen with dirty hands, you can adjust the screen time on your device so that it does not turn off after a short period of time. This will help you to avoid touching the screen so often and help you refer to the recipe more easily.
Taking out bins
Food waste should be disposed of in the appropriate bins in the kitchen. This should be regularly removed when the bins are full and put in the designated outside large bin area to avoid any infestation of flies, pests and a foul smell.
If you are taking the bins out or emptying recycling containers, it is important to wash your hands after. This is especially important after handling dry rubbish as it’s not always obvious that it could be contaminated with bacteria.
You may find it helpful to establish a rota amongst your housemates to encourage good hygiene practices.
Eating out and ordering food safely
When you eat out or order food when you move to a new town or city, it’s important to consider their food hygiene before ordering. If a restaurant has good food hygiene practices in place, you can eat with confidence and are less at risk of food poisoning.
You can find out a restaurant’s level of food hygiene in advance by checking their food hygiene rating.
Food Hygiene Rating Scheme
When you go to a restaurant or order a takeaway, it’s important to check the food hygiene rating of the business, particularly if you are unfamiliar with them.
The ratings are a snapshot of the standards of food hygiene found at the time of inspection. This includes the handling of food, how food is stored, how food is prepared, the cleanliness of facilities and how food safety is managed.
The hygiene standards found at the time of inspection are then rated on a scale:
- 5 is top of the scale, this means the hygiene standards are very good and fully comply with the law
- 0 is at the bottom of the scale, this means urgent improvement is necessary.
Managing a food allergy
Living with a food allergy can affect people in different ways. Having a food allergy can pose extra challenges to daily tasks and have unexpected impacts on new experiences at university or when living with others for the first time.
We have advice for young people with a food allergy on navigating the new experiences that come with student life that can bring about extra risks.
Living with a food allergy
For many, living away from home, can be the first time that you take full responsibility for managing a food allergy.
You will need to get used to checking all food labels and understand ingredients labelling. Don’t assume that a food will be safe to eat without checking.
Some food and drink, including spirits, sauces and ready-made meals may contain allergens. Ingredients can change from the last time you had it.
Shared living with a food allergy
Living with a food allergy, you may find that you are asked a lot of questions and that you have to ask about different ingredients. Try not to feel uncomfortable asking these questions as they are important to your safety. Ask direct questions to make sure people understand the severity for you and that you get accurate information.
Communicating with partners and friends is important, so that they know whether to avoid certain food types. This will make them better understand how they can help you manage your food allergy.
Eating out and ordering a takeaway with a food allergy
It is important to speak to the restaurant every time when you eat out, order a takeaway or get food delivered. Don’t assume that a meal is safe just because you have had it before.
This is because the recipe, ingredients, chef or kitchen staff may have changed. Often it is not clear, unless you ask, which allergens are in meals and what quantity they are in.
If you don’t feel that the person you’re ordering from fully understands your needs, ask to speak to someone else. If you’re not confident they understand your allergy, consider ordering from elsewhere.
