Food Safety Tips: 5 Keys to Safer Food at Home

The most important food safety tips follow the WHO’s five keys: keep hands and surfaces clean, separate raw and cooked food, cook food thoroughly, keep food at safe temperatures, and use safe water and fresh ingredients. These simple habits prevent most cases of food poisoning at home and protect the people you cook for.

Unsafe food can carry bacteria, viruses, parasites or chemicals that cause illness ranging from a mild upset stomach to serious, even life-threatening conditions. Young children, pregnant women, older adults and people with weakened immunity are most at risk. In hot climates like the UAE and Pakistan, bacteria multiply quickly, which makes good habits even more important.

Why does food safety matter?

Foodborne illness is common worldwide and largely preventable. It can cause vomiting, diarrhoea, stomach cramps and fever, and some infections lead to dehydration or longer-term complications. Beyond health, unsafe food affects schools, workplaces, tourism and trade, which is why governments and food businesses follow strict safety systems.

At home, you are the last line of defence. Even food that was safe when you bought it can become unsafe if it is stored, handled or cooked poorly.

What are the five keys to safer food?

1. Keep clean

• Wash your hands with soap and water before handling food, after touching raw meat, after using the toilet and after changing nappies.
• Clean chopping boards, knives, worktops and sponges regularly with hot, soapy water.
• Keep pets, insects and pests away from food and kitchen areas.

2. Separate raw and cooked

• Use separate chopping boards and knives for raw meat, poultry and fish.
• Store raw meat in sealed containers on the bottom shelf of the fridge so juices cannot drip onto other foods.
• Never put cooked food back on a plate that held raw meat.

3. Cook thoroughly

• Cook meat, poultry, eggs and seafood until piping hot all the way through. The WHO advises a core temperature of 70°C.
• Chicken and minced meat, such as kebabs and burgers, should have no pink meat and juices should run clear.
• Reheat leftovers until steaming hot throughout, and only reheat them once.

4. Keep food at safe temperatures

• Keep your fridge at 5°C or below and your freezer at around −18°C.
• Do not leave cooked food at room temperature for more than two hours, and for less time in very hot weather.
• Cool leftovers quickly, cover them and refrigerate. Use within about two days.
• Defrost frozen food in the fridge or microwave, not on the counter.

5. Use safe water and ingredients

• Use safe drinking water for cooking, washing produce and making ice.
• Wash fruit and vegetables well, especially those eaten raw.
• Avoid food past its “use by” date, and do not buy dented, swollen or damaged tins.
• Choose pasteurised milk and dairy products.

Common food safety hazards to know

Food can become unsafe in several ways. Understanding the main hazards helps you spot risks.

Food safety tips for hot climates, gatherings and Ramadan

Large family meals, Eid feasts, weddings and iftar gatherings are a joy, but big batches of food left out for hours can be risky.

• Cook rice, biryani and curries close to serving time, or cool and refrigerate them quickly.
• Cooked rice needs special care: cool it within an hour if possible, keep it in the fridge and use it within a day.
• Keep hot food hot and cold food cold. Do not leave dishes like raita, hummus or salads in the sun.
• For suhoor, prepare food fresh or store it safely in the fridge after iftar.
• Use cool bags with ice packs for picnics and trips to the beach or desert.
• Be cautious with street food that has been sitting out, and choose busy stalls where food is cooked fresh.

Food safety in restaurants and food businesses

Food businesses follow structured safety systems, such as HACCP (Hazard Analysis and Critical Control Points), to identify and control risks at every step from delivery to serving. Local authorities inspect premises and set rules on hygiene, staff training and temperature control. You can learn more about professional standards in our article on food hygiene from farm to fork.

As a customer, look for clean premises, staff who handle food hygienically and food served at the right temperature. If something seems wrong, it is fine to send it back.

When to see a doctor or nutrition professional

Most mild food poisoning gets better in a few days with rest and fluids. See a doctor if you have:

• Signs of dehydration, such as very little urine, dizziness or a dry mouth.
• Blood in your stools or vomit.
• A high fever, severe stomach pain or symptoms lasting more than a few days.
• Symptoms while pregnant, or in a baby, young child, older adult or someone with weak immunity.

Seek emergency help for signs of a severe allergic reaction, such as swelling of the lips or throat or difficulty breathing. For more on symptoms and recovery, read our guide to food poisoning.

Frequently asked questions

How long can cooked food be left out?

Generally no more than two hours at room temperature, and less in hot weather. After that, bacteria can multiply to unsafe levels, so refrigerate leftovers promptly.

Should I wash raw chicken before cooking?

No. Washing raw chicken can splash bacteria around your sink and kitchen. Thorough cooking kills the bacteria, so it is safer to cook it without rinsing.

Is it safe to refreeze food?

Raw food defrosted in the fridge can be cooked and then frozen again. Avoid refreezing food that was thawed at room temperature, and never refreeze reheated leftovers.

Can you tell if food is safe by smelling it?

Not always. Many bacteria that cause illness do not change the smell, taste or look of food. Follow use-by dates and storage guidance instead.
