Symptoms of food poisoning associated with contaminated poultry may include:
-
Diarrhea.
-
Abdominal cramps.
-
Fever.
-
Nausea.
-
Vomiting.
-
General weakness.
Symptoms may begin within hours or take several days to appear, depending on the organism responsible.
How to store cooked chicken safely
Cooked chicken can generally be stored safely for three to four days in a refrigerator maintained at 40°F (4°C) or below.
However, proper handling is essential.
Follow these recommendations:
-
Refrigerate cooked chicken within two hours of cooking or serving.
-
If the surrounding temperature is above 90°F (32°C), refrigerate it within one hour.
-
Store chicken in shallow, airtight containers.
-
Keep raw poultry separate from cooked food.
-
Reheat leftovers to an internal temperature of 165°F (74°C).
-
Use a food thermometer to check the thickest part of the meat.
If chicken has remained at room temperature for more than two hours, it should be discarded. Reheating cannot reliably make improperly stored chicken safe.
3. Seafood and Fish: Highly Perishable Foods That Need Careful Refrigeration
Fish, shrimp, crab, mussels, and other seafood are nutritious foods that provide protein and, depending on the type, beneficial omega-3 fatty acids.
However, seafood is particularly perishable.
Its quality can deteriorate quickly if it is not kept cold, and certain seafood products can be associated with specific foodborne hazards.
For example, raw or undercooked seafood may contain harmful bacteria, viruses, or parasites.
Cooked seafood can also become contaminated during handling or storage.
One concern involves Vibrio bacteria, which can naturally occur in certain marine environments and are particularly associated with raw or undercooked shellfish, especially oysters.
Another concern involves histamine poisoning, sometimes called scombroid poisoning. This can occur when certain fish, including tuna, mackerel, and mahi-mahi, are not kept cold enough after being caught.
Bacteria can produce histamine in the fish, and this substance is not reliably destroyed by cooking, freezing, or reheating.
Symptoms may include facial flushing, headache, a burning sensation in the mouth, rash, palpitations, and gastrointestinal discomfort.
Why seafood should not be left out overnight
Unlike many shelf-stable foods, seafood can deteriorate rapidly when exposed to warm temperatures.
Leaving cooked fish or shrimp on the kitchen counter overnight creates an opportunity for bacteria to multiply.
Even if the seafood still smells acceptable, that does not guarantee safety.
Some types of seafood may also develop hazards that cannot be corrected simply by reheating.
How to store seafood leftovers safely
-
Refrigerate cooked seafood within two hours.
-
Use an airtight container to prevent contamination and odor transfer.
-
Keep the refrigerator at 40°F (4°C) or below.
-
Use refrigerated cooked fish and shellfish within three to four days, provided they were handled properly.
-
Reheat leftovers thoroughly when appropriate.
-
Discard seafood that has been left at room temperature beyond the recommended time.
People who are pregnant, older adults, young children, and individuals with weakened immune systems should take additional care with seafood, particularly raw or undercooked products.
Remember: Fresh seafood is not automatically safe seafood. Proper cooking, cold storage, and careful handling all matter.
4. Cooked Potatoes: A Food That Can Become Unsafe When Stored Incorrectly
Potatoes are a familiar ingredient in many kitchens.
They can be boiled, roasted, mashed, baked, or added to soups and salads. Because they are inexpensive and filling, people often prepare more than they need and save the remainder for another meal.
But cooked potatoes also require proper storage.
One important concern involves Clostridium botulinum, the bacterium that produces the toxin responsible for botulism.
Botulism is rare but potentially life-threatening.
The bacterium can grow and produce toxin under low-oxygen conditions when other environmental conditions are suitable.
A particular concern is baked potatoes wrapped in aluminum foil and then left at room temperature. The foil can create a low-oxygen environment, especially when the potato remains warm for an extended period.
If the potato is not refrigerated promptly, there may be conditions that allow dangerous bacterial growth.
This does not mean that every foil-wrapped potato is dangerous. The risk is associated with improper time and temperature control.
What makes botulism particularly concerning?
Botulinum toxin affects the nervous system.
Symptoms can include:
-
Blurred or double vision.
-
Drooping eyelids.
-
Difficulty speaking.
-
Difficulty swallowing.
-
Muscle weakness.
-
Difficulty breathing.
Botulism is a medical emergency. Anyone who develops symptoms suggesting botulism should seek immediate emergency medical care.
How to store cooked potatoes safely
-
Remove foil from baked potatoes before refrigerating.
-
Refrigerate cooked potatoes within two hours.
-
Store them in clean, covered containers.
-
Keep them at 40°F (4°C) or below.
-
Use refrigerated leftovers within three to four days.
-
Reheat thoroughly when appropriate.
Do not leave baked potatoes wrapped in foil on the counter overnight.
