To avoid illness, use pasteurized eggs when recipes call for raw or lightly cooked eggs. Pasteurized eggs have been heat-treated to kill bacteria, making them safer for consumption. Additionally, ensure eggs are fully cooked before eating, with firm whites and yolks.
5. Improperly Washed Fruits and Vegetables
Fruits and vegetables that are not properly washed can carry bacteria like E. coli and salmonella, as well as harmful pesticides. These contaminants can cling to the surface of produce, posing a risk when consumed. Symptoms of contamination include diarrhea, nausea, and vomiting.
Leafy greens, berries, and other fresh produce that are often eaten raw are particularly susceptible. Contaminants can come from soil, water, and handling during transportation and at the store. Even organic produce needs thorough washing to ensure safety.
Always wash all fruits and vegetables under running water before eating them. Use a brush for items with tough skins to remove dirt and potential bacteria. Washing not only removes bacteria but also helps eliminate pesticide residues, making your produce safer to eat.
6. Sprouts
Sprouts, such as alfalfa, mung bean, and clover sprouts, are grown in warm, moist conditions ideal for the growth of bacteria like salmonella and E. coli. These conditions make sprouts a high-risk food, as the bacteria can thrive and multiply quickly. Consuming contaminated sprouts can lead to severe foodborne illnesses.
Alfalfa sprouts, bean sprouts, radish sprouts, and clover sprouts are commonly used in salads, sandwiches, and other dishes. Despite their nutritional benefits, they carry significant risks due to potential bacterial contamination. Outbreaks of foodborne illness linked to sprouts have been well-documented.
To reduce the risk, cook sprouts thoroughly before consuming them, as high heat can kill harmful bacteria. Alternatively, you might consider avoiding raw sprouts altogether, especially if you belong to a high-risk group such as pregnant women, the elderly, or those with weakened immune systems.
7. Deli Meats
Deli meats, including ham, turkey, and salami, can be contaminated with listeria, a bacterium that can thrive even in refrigerated conditions. Listeria infection can cause severe illness, particularly in pregnant women, the elderly, and those with weakened immune systems. Symptoms include fever, muscle aches, and gastrointestinal issues.
The contamination can occur during processing or handling in delis. Sliced meats are especially susceptible because the slicing equipment can harbor bacteria if not properly cleaned. Listeria can grow on these meats even if they are kept in the fridge.
To minimize risk, opt for deli meats that have been pre-packaged in vacuum-sealed conditions, which are less likely to be contaminated. Always heat deli meats to steaming hot before consuming, especially if you are in a high-risk group.
8. Pre-Packaged Salads

Pre-packaged salads can be a convenient option but carry a higher risk of contamination with bacteria like E. coli and listeria. These bacteria can be present due to improper washing or cross-contamination during processing. Illnesses from contaminated salads can result in severe stomach pain, diarrhea, and fever.
Products such as bagged lettuce, pre-cut fruit, and mixed salads are particularly prone to contamination. The cutting and packaging processes can introduce bacteria, which can multiply if the product is not stored correctly.
To reduce risk, thoroughly wash pre-packaged salads even if they are labeled as “pre-washed” or “ready to eat.” This extra step can help remove any residual bacteria and ensure the safety of your food.
9. Raw Flour
Raw flour can be contaminated with E. coli, which can cause serious illness if consumed. The bacteria can survive in flour as it is not treated to kill bacteria during the milling process. Consuming raw dough or batter made with contaminated flour can lead to symptoms such as severe abdominal cramps, diarrhea, and vomiting.
Common sources of exposure include raw cookie dough, cake batter, and other homemade treats that use raw flour. Even tasting a small amount of raw dough can be risky.
To prevent illness, avoid eating any raw dough or batter. Always cook or bake foods containing flour to the proper temperatures, as high heat will kill harmful bacteria present in the flour.
10. Soft Cheeses
Soft cheeses, such as brie, camembert, and feta, made from unpasteurized milk can harbor listeria, a bacterium that causes serious infections. These cheeses are particularly risky for pregnant women, the elderly, and those with weakened immune systems, leading to symptoms like fever, muscle aches, and gastrointestinal issues.
Listeria can contaminate soft cheeses during production or through handling. The moist and soft texture of these cheeses provides an ideal environment for bacterial growth.
Opt for soft cheeses made from pasteurized milk to reduce the risk of listeria contamination. Always check labels to ensure the cheese has been pasteurized and avoid consuming soft cheeses that have been left unrefrigerated for extended periods.
11. Leftover Rice
Leftover rice can become a breeding ground for Bacillus cereus, a bacterium that can cause food poisoning. Bacillus cereus spores can survive cooking and multiply if the rice is left at room temperature for too long. Symptoms of illness include vomiting and diarrhea.
The risk arises when cooked rice is not stored correctly. If rice is left out for several hours or not refrigerated promptly, bacteria can grow rapidly.
To prevent foodborne illness, refrigerate leftover rice within two hours of cooking. Reheat rice thoroughly before eating, ensuring it reaches a high temperature to kill any bacteria that may have grown during storage.
12. Cold Salads
Cold salads, such as potato salad, pasta salad, and coleslaw, can be contaminated with bacteria like salmonella and listeria if not handled and stored properly. These salads often contain ingredients that can spoil quickly, leading to foodborne illness with symptoms like stomach cramps, nausea, and diarrhea.
Contamination can occur during preparation if ingredients are not kept at the correct temperature. Additionally, cross-contamination from utensils or surfaces can introduce harmful bacteria.
