How to Reduce the Risk of Foodborne Illness at Home

Foodborne illnesses, commonly known as food poisoning, affect millions of people every year. They are caused by consuming food or beverages contaminated with harmful bacteria, viruses, parasites, or toxins. Fortunately, many foodborne illnesses can be prevented by following proper food safety practices at home.

Simple habits like washing your hands, cooking food thoroughly, and storing food correctly can significantly reduce the risk of foodborne infections.

What Is Foodborne Illness?

Foodborne illness occurs when harmful microorganisms or toxins contaminate food and are consumed.

Common causes include:

• Bacteria (such as Salmonella, E. coli, and Listeria)
• Viruses (such as Norovirus)
• Parasites
• Chemical contaminants
• Improper food handling

Common Symptoms of Foodborne Illness

Symptoms may include:

• Nausea
• Vomiting
• Diarrhea
• Stomach cramps
• Fever
• Headache
• Weakness
• Dehydration

Symptoms can range from mild to severe depending on the cause and the individual’s overall health.

Tips to Reduce the Risk of Foodborne Illness at Home

1. Wash Your Hands Properly

Always wash your hands with soap and clean running water for at least 20 seconds, especially:

• Before preparing food
• Before eating
• After handling raw meat, poultry, seafood, or eggs
• After using the restroom
• After touching pets
• After taking out the trash

Hand hygiene is one of the most effective ways to prevent food contamination.

2. Keep Your Kitchen Clean

Regularly clean:

• Countertops
• Cutting boards
• Knives
• Sinks
• Kitchen towels
• Cooking utensils

Use clean cloths or disposable paper towels to wipe surfaces.

3. Separate Raw and Cooked Foods

Avoid cross-contamination by keeping raw foods away from cooked or ready-to-eat foods.

Use separate cutting boards for:

• Raw meat
• Vegetables
• Fruits
• Bread

Never place cooked food back onto a plate that previously held raw meat.

4. Cook Foods Thoroughly

Cooking food to the appropriate internal temperature helps destroy harmful microorganisms.

Pay particular attention to:

• Chicken
• Turkey
• Ground meat
• Seafood
• Eggs

Use a food thermometer when appropriate to ensure foods reach safe cooking temperatures.

5. Refrigerate Perishable Foods Promptly

Do not leave perishable foods at room temperature for extended periods.

Store foods such as:

• Dairy products
• Meat
• Poultry
• Seafood
• Cooked leftovers

Refrigerate leftovers within 2 hours, or within 1 hour if the room temperature is above 32°C (90°F).

6. Store Food Correctly

Keep your refrigerator at 4°C (40°F) or below and your freezer at −18°C (0°F) or below.

Store raw meat on the lowest shelf in sealed containers to prevent juices from dripping onto other foods.

7. Wash Fruits and Vegetables

Rinse fresh fruits and vegetables under clean running water before eating, peeling, or cooking them.

Do not use soap or detergents unless specifically recommended for produce.

8. Check Expiration Dates

Before consuming packaged foods:

• Check expiration or “use by” dates.
• Discard foods that appear spoiled or have an unusual smell, texture, or color.

9. Use Safe Drinking Water

Use clean, safe water for:

• Drinking
• Cooking
• Washing produce
• Preparing infant formula

If the safety of your water supply is uncertain, follow local public health recommendations.

10. Reheat Leftovers Safely

When reheating leftovers:

• Heat food thoroughly until steaming hot.
• Stir food evenly during reheating to ensure consistent temperature.

Avoid reheating the same leftovers multiple times.

Foods That Require Extra Caution

Certain foods are more likely to become contaminated if not handled properly.

Take extra care with:

• Raw poultry
• Raw meat
• Seafood
• Eggs
• Unpasteurized milk and dairy products
• Soft cheeses made from unpasteurized milk
• Ready-to-eat deli meats
• Cooked rice left at room temperature
• Fresh sprouts

These foods should always be stored, prepared, and cooked according to food safety recommendations.

Common Food Safety Mistakes to Avoid

Thawing Food on the Kitchen Counter

Frozen food should never be thawed at room temperature.

Instead, thaw food:

• In the refrigerator
• In cold water (changing the water regularly)
• In the microwave if cooking immediately afterward

Washing Raw Chicken

Washing raw chicken is not recommended, as it can spread bacteria to kitchen surfaces, utensils, and nearby foods through splashing water.

Cooking chicken thoroughly is the safest way to eliminate harmful bacteria.

Leaving Food Out Too Long

Cooked foods should not remain at room temperature for extended periods.

Prompt refrigeration helps reduce bacterial growth.

Using the Same Cutting Board

Using one cutting board for both raw meat and fresh produce increases the risk of cross-contamination.

Keep separate cutting boards whenever possible.

Ignoring Refrigerator Temperature

Your refrigerator should remain at 4°C (40°F) or below to help keep perishable foods safe.

Check appliance temperatures regularly if possible.
