People Often Consume This Food Without Knowing It Could Contain Harmful Parasites

Some everyday foods can carry parasites when they are raw, undercooked, or contaminated, although that does not mean the food itself is unsafe when properly prepared. Raw or undercooked fish and squid are notable examples because they can transmit parasites such as Anisakis, which may cause abdominal pain, nausea, vomiting, diarrhea, and other digestive symptoms. Undercooked meat can also carry certain parasites, including Trichinella, while raw aquatic plants and unwashed fruits and vegetables can become contaminated through unsafe water, soil, or animal or human waste. The important message is not to fear these foods, but to understand that proper food preparation dramatically reduces the risk.

One of the biggest concerns is eating raw or insufficiently cooked seafood or meat. Sushi, sashimi, ceviche, raw shellfish, and undercooked meat can carry organisms that may cause foodborne infections. The CDC recommends cooking fish to at least 145°F (63°C), while safe cooking temperatures for meat vary depending on the type. Thorough cooking is particularly important for wild game and certain meats because some parasites may survive methods such as smoking, drying, or curing alone. Fresh produce also deserves attention: washing fruits and vegetables under running water can help remove contaminants, although washing does not eliminate every type of pathogen.

The safest approach is simple: clean, separate, cook, and chill. Wash your hands and kitchen surfaces, keep raw meat and seafood away from ready-to-eat foods, cook foods to appropriate internal temperatures, and refrigerate perishable foods promptly. People who are pregnant, very young, older, or immunocompromised should take extra precautions because foodborne infections can be more serious for them. If you develop persistent abdominal pain, vomiting, diarrhea, fever, unusual swelling, or other concerning symptoms after eating raw or undercooked food, seek medical advice and tell the clinician what you consumed.
