## Washing hands

Our hands are one of the main ways that germs are spread. Harmful bacteria can be spread very easily from people's hands to food, work surfaces and equipment.

It's always important to wash them thoroughly with soap and warm water before handling food, and especially after touching raw food, the bin, pets, and going to the toilet.

Find out how to wash your hands correctly.

## Storing and preparing meat

Raw meat, including poultry, can contain harmful bacteria that can spread easily to anything it touches, including food, worktops, tables, chopping boards, and knives.

Take particular care to keep raw food separate from ready-to-eat foods such as bread, salad and fruit. These foods won't be cooked before you eat them, so any germs that get on to them won't be killed.

Find out why you should never wash raw chicken.

Hygiene tips:

-   use different chopping boards for raw and ready-to-eat foods
-   store raw meat and fish in a sealed container on the bottom shelf of the fridge

## Cooking

Cooking food at the right temperature will ensure any harmful bacteria are killed. Check that food's steaming hot throughout before you eat it.

The foods below need to be cooked thoroughly before eating:

-   poultry
-   pork
-   offal, including liver
-   burgers
-   sausages
-   rolled joints of meat
-   kebabs

### Burgers and sausages

When cooking burgers, sausages, chicken, and pork, cut into the middle to check that the meat's no longer pink, the juices run clear and it's steaming hot throughout.

### Chicken

When cooking a whole chicken or bird, pierce the thickest part of the leg (between the drumstick and the thigh) to check there's no pink meat and the juices are no longer pink or red.

### Pork

Pork joints and rolled joints shouldn't be eaten pink or rare. To check when these types of joint are ready to eat, put a skewer into the centre of the meat and check there's no pink meat and the juices run clear.

### Beef and lamb

It's safe to serve steak and other whole cuts of beef and lamb rare (not cooked in the middle) or blue (seared on the outside) as long as they have been properly sealed by cooking them quickly at a high temperature on the outside only. Bacteria is usually only found on the outer surfaces of these types of meat.

## Cooking meat on a barbecue

The safest option is to fully cook food in your oven and then put the cooked food on the barbecue for a short time so the flavour can develop.

This can be an easier option if you're cooking for a lot of people at the same time.

If you're only cooking on the barbecue, the two main risk factors are:

-   undercooking meat
-   spreading germs from raw or undercooked meat on to food that's ready to eat

When you're cooking most types of meat on a barbecue, such as poultry (chicken and turkey, for example), pork, burgers or sausages, make sure:

-   the coals are glowing red with a powdery grey surface before you start cooking, as this means they're hot enough
-   frozen meat is fully defrosted before you cook it
-   you turn the meat regularly and move it around the barbecue to cook it evenly

Most types of meat are safe to eat only when:

-   the meat's steaming hot throughout
-   there's no pink meat visible when you cut into the thickest part
-   any juices run clear

Cooking with disposable barbecues can take longer.

Meat, such as steaks and joints of beef or lamb, can be served rare (not cooked in the middle) as long as the outside has been properly cooked. This will kill any bacteria on the outside of the meat.

Food made from any type of minced meat, such as pork sausages and beef burgers, must be cooked thoroughly all the way through.

## Acrylamide in starchy food

Acrylamide is a chemical that's created when many foods, particularly starchy foods like potatoes and bread, are cooked at high temperatures (over 120C), such as when baking, frying, grilling, toasting, and roasting.

Boiling, steaming and microwave cooking are unlikely to create acrylamide.

There's evidence to show acrylamide has the potential to cause cancer.

The Food Standards Agency has the following tips to reduce your risk of acrylamide at home:

-   **go for gold**  – aim for a golden yellow colour or lighter when frying, baking, toasting or roasting starchy foods like potatoes, root vegetables and bread.
-   **check the pack**  – follow the cooking instructions carefully when frying or oven-heating packaged food products like chips, roast potatoes and parsnips.
-   **don't keep raw potatoes in the fridge**  – storing raw potatoes in the fridge can increase overall acrylamide levels if they're then cooked at high temperatures, such as roasting or frying.
-   **eat a varied and balanced diet**  – while we can't completely avoid risks like acrylamide in food, eating a healthy, balanced diet will help reduce your risk of cancer.

For more information, read Starchy foods and carbohydrates.

## Washing fruit and vegetables

Wash fruit and vegetables under cold running water before you eat them. This helps remove visible dirt and germs that may be on the surface. Peeling or cooking fruit and vegetables can also remove these germs.

Never use washing-up liquid or other household cleaning products to clean fruit and vegetables, as they're not intended for human consumption and you may accidentally leave some of the product on the food.
