Food Safety for Older Adults: Storage, Leftovers and Warning Signs

By Silver Sitters

Adults 65 and older are more vulnerable to serious foodborne illness. Careful handling, cooking and storage reduce risk. For families in Palm Beach County, this includes planning for warm weather during shopping, deliveries, picnics and the trip home from a restaurant.

Keep hot food hot and cold food cold

Keeping hot food at room temperature does not prevent bacteria from growing. When holding cooked food for serving, keep it at 140°F or warmer. Keep cold food at 40°F or colder. Use a thermometer rather than guessing from appearance or touch.

Refrigerate perishable food within two hours, or within one hour when the air temperature is above 90°F. Discard food that has been left out beyond these limits without safe hot or cold holding. Include travel time in the plan; if leftovers cannot be kept safely cold or refrigerated promptly, do not save them.

Handle leftovers promptly

Divide large quantities into shallow containers for rapid cooling and put them in the refrigerator promptly. Hot food can go directly into the refrigerator; it does not need to sit out until it reaches room temperature.

Use properly handled refrigerated leftovers within three to four days or freeze them. Reheat leftovers to 165°F, checking with a food thermometer. A safe appearance or smell does not establish that food was stored safely.

Reduce contamination during preparation

• Wash hands and clean food-preparation surfaces and utensils.
• Keep raw meat, poultry, seafood and their juices separate from ready-to-eat foods.
• Rinse fresh produce under running water.
• Cook food to the appropriate safe internal temperature, using a food thermometer.
• Choose safer alternatives to raw or undercooked meat, seafood and eggs, and unpasteurized milk. For older adults, reheat deli meats and hot dogs to steaming hot or 165°F.

Know when to seek medical advice

Contact a clinician for severe symptoms, including bloody diarrhea, diarrhea lasting more than three days, fever over 102°F, vomiting that prevents keeping liquids down or signs of dehydration such as reduced urination and dizziness. Seek help sooner when symptoms are severe or concerning; do not wait for a time threshold. Call 911 for a life-threatening emergency.

When arranging meal preparation or grocery assistance, share storage instructions, allergies and the person’s dietary or swallowing plan with everyone involved.
