Some foods are more susceptible to these germs and require special care during shopping, storage, and preparation. Knowing these foods and how to handle them properly is a fundamental step in preventing foodborne illnesses. ## Foods at Risk Foods most susceptible to containing harmful germs include [\[3\]](): - **Raw or undercooked poultry, meat, seafood, and eggs:** These products are a breeding ground for bacteria if not cooked to safe internal temperatures. - **Raw or undercooked sprouts:** Sprouts can carry harmful bacteria due to how they are grown in a warm, moist environment. - **Unwashed fruits and vegetables:** Germs can be transferred from the soil or during handling to the surface of fruits and vegetables. - **Cut melons:** Once cut, the internal surface of melons is exposed to germs that may be present on the outer rind or transferred from contaminated surfaces. - **Unpasteurized milk, juices, cider, and soft cheeses:** The pasteurization process kills harmful germs, so unpasteurized products carry a higher risk. - **Raw dough or batter made with uncooked flour:** Raw flour can contain harmful bacteria, which are only killed by cooking. ## Tips for Safely Handling High-Risk Foods To reduce the risk of food poisoning, follow these guidelines when handling the mentioned foods [\[1\]](): - **Clean:** Wash your hands thoroughly with soap and water for at least 20 seconds before and after touching food, especially after handling raw meat, poultry, seafood, eggs, or flour [\[3\]](). Wash fruits and vegetables under running water before eating or cutting. Clean surfaces and kitchen utensils with hot, soapy water. - **Separate:** Separate raw foods (meat, poultry, seafood, eggs) from ready-to-eat foods. Use different cutting boards and utensils for each type of food. When shopping, place raw meat in separate bags to prevent juices from leaking onto other foods. In the refrigerator, store raw meat in sealed containers or wrap it well and place it on the lower shelves to prevent juices from dripping onto other foods [\[3\]](). - **Cook:** Cook food to a safe internal temperature to kill germs. Use a food thermometer to ensure food reaches the correct temperature. For example, all poultry should be cooked to 165°F (74°C), ground meat to 160°F (71°C), and fish until the flesh is opaque and separates easily with a fork [\[3\]](). - **Chill:** Refrigerate perishable foods promptly. Do not leave perishable foods at room temperature for more than two hours, or one hour if the air temperature is above 90°F (32°C) [\[2\]](). Set your refrigerator temperature to 40°F (4°C) or lower, and the freezer to 0°F (-18°C) or lower [\[2\]](). ## Signs of Danger and When to Seek Help Contaminated foods may not look spoiled or smell bad, but they can still cause serious illness [\[2\]](). If you suspect you have eaten contaminated food and develop symptoms of food poisoning like nausea, vomiting, diarrhea, or fever, it is important to pay attention. In most cases, mild food poisoning can be managed at home. However, if symptoms are severe, such as severe dehydration, high fever (greater than 102°F or 39°C), bloody diarrhea, or frequent vomiting that prevents keeping liquids down, you should seek immediate medical attention. Young children, the elderly, pregnant women, and people with weakened immune systems are more prone to serious complications from food poisoning. ## Storing and Reheating Leftovers Storing leftovers properly is critical to prevent bacterial growth. Refrigerate cooked leftovers in shallow, covered containers within two hours of cooking [\[3\]](). Most cooked leftovers can be stored safely in the refrigerator for 3 to 4 days. When reheating leftovers, ensure they reach an internal temperature of 165°F (74°C) to kill any bacteria that may have grown during storage [\[3\]](). Do not reheat food more than once.
