Place the thermometer in a location where it can provide a useful reading, and check it periodically.
If the refrigerator consistently stays above 40°F (4°C), adjust the settings or have the appliance inspected.
A refrigerator that is too warm may allow bacteria to multiply more quickly, even if food still feels cold when touched.
2. Refrigerate perishable foods promptly
After shopping, put refrigerated foods away as soon as possible.
Do not leave groceries in a hot vehicle while completing other errands. During warm weather, temperatures inside a parked car can rise rapidly.
The general recommendation is to refrigerate perishable foods within two hours. If the surrounding temperature is above 90°F (32°C), the limit becomes one hour.
The same rule applies to cooked meals, deli meat sandwiches, dairy products, and other perishable foods taken out of refrigeration.
3. Cool leftovers in shallow containers
Large pots of soup, rice, stew, or cooked vegetables can remain warm in the center for a long time.
Placing a large, hot container directly into the refrigerator may also make it harder for the appliance to maintain a consistent temperature.
A better approach is to divide food into smaller portions and use shallow containers. This allows heat to escape more quickly.
Do not wait for food to remain at room temperature for several hours before refrigerating it.
4. Store raw and cooked foods separately
Cross-contamination is a major cause of foodborne illness.
Raw meat, poultry, and seafood may contain harmful bacteria. If their juices leak onto ready-to-eat foods, those foods can become contaminated.
Store raw meat in sealed containers on the lowest refrigerator shelf. This reduces the chance that liquid will drip onto vegetables, cheese, leftovers, or prepared meals.
Keep ready-to-eat foods covered and separate from raw ingredients.
5. Use airtight containers
Proper containers help protect food from contamination, moisture loss, and odor transfer.
They also make it easier to identify what is inside and how long it has been stored.
Choose food-safe containers with secure lids. Avoid placing leftovers in containers that previously held chemicals or non-food substances.
For foods such as cooked rice, soup, and sliced meat, individual portions can make storage and reheating more convenient.
6. Label leftovers with dates
One of the simplest ways to reduce food waste and avoid eating old leftovers is to label containers.
Write down the date the food was prepared or opened.
This prevents the common situation in which someone finds an unidentified container at the back of the refrigerator and has no idea how long it has been there.
A small label or piece of masking tape can make a major difference.
7. Avoid overcrowding the refrigerator
Cold air needs space to circulate.
When shelves are packed too tightly, some areas may become warmer than others. This can make temperature control less consistent.
Arrange foods so that air can move around them. Avoid blocking refrigerator vents.
Do not rely on the door shelves for particularly temperature-sensitive foods because temperatures in the door may fluctuate more frequently.
8. Clean shelves and drawers regularly
Spills from raw meat, dairy products, and other foods can introduce bacteria to refrigerator surfaces.
Clean spills immediately with appropriate household cleaning products, following the manufacturer's instructions.
Periodically remove shelves and drawers when possible and wash them with warm, soapy water.
Dry surfaces before replacing food.
A clean refrigerator reduces opportunities for contamination and makes it easier to notice expired or damaged products.
9. Follow the first-in, first-out method
Restaurants and professional kitchens often use a system known as FIFO, meaning first in, first out.
The principle is simple: use older products before newer ones.
When buying a new package of deli meat or cheese, move the older package toward the front and place the new one behind it.
This small organizational habit helps prevent food from being forgotten until it is no longer safe to eat.
10. Understand the difference between expiration and storage dates
Food labels can be confusing.
Some dates are primarily intended to indicate quality, while others may relate to safety or product handling.
The meaning of labels varies by country and product category. A date printed on a package should not be treated as a universal guarantee that food is safe regardless of how it has been stored.
Once a package is opened, the manufacturer's recommended storage period may change.
For example, a sealed product might have a relatively long shelf life, but the recommended period after opening could be only a few days.
Always read the instructions carefully.
CHAPTER 5: THE WARNING SIGNS OF FOODBORNE ILLNESS AND THE HABITS THAT PROTECT YOUR FAMILY
Foodborne illness can affect anyone, regardless of age, lifestyle, or general health.
In many cases, symptoms are relatively mild and resolve without specific treatment. However, certain infections can cause serious complications, particularly in vulnerable individuals.
Understanding common symptoms and knowing when to seek medical attention are important parts of food safety.
Common symptoms of foodborne illness
Symptoms vary depending on the microorganism or toxin involved.
Common signs include:
-
Nausea.
-
Vomiting.
-
Diarrhea.
-
Abdominal pain or cramps.
-
Fever.
-
Headache.
-
Muscle aches.
-
General weakness.
Symptoms may begin within a few hours after eating contaminated food, or they may take several days or longer to appear.
This means that the most recent meal is not necessarily the source of the illness.
For example, some bacterial infections have incubation periods that extend over several days. Identifying the exact source may require medical evaluation and laboratory testing.
When should you seek medical attention?
Most people with mild food poisoning recover with rest and adequate fluid intake.
However, certain symptoms should never be ignored.
Seek medical advice if you experience:
-
Bloody diarrhea.
-
Diarrhea lasting more than three days.
-
A high fever.
-
Repeated vomiting that prevents you from keeping liquids down.
-
Signs of dehydration.
-
Severe or persistent abdominal pain.
-
Confusion, fainting, or unusual weakness.
