Some foods can look perfectly fresh and harmless while still carrying microscopic parasites if they are contaminated or improperly handled. That doesn’t mean you should fear these foods, but knowing where risks can occur can help you prepare meals more safely.
Raw or undercooked fish is one example. Certain freshwater fish and some marine species can carry parasites that may infect people when the fish is eaten raw or insufficiently cooked. Proper cooking or appropriate freezing methods can greatly reduce this risk.
Undercooked pork is another food that deserves attention. Pork can potentially contain parasites when it comes from contaminated sources or is not cooked properly. Thorough cooking is one of the simplest ways to make it safer.
Fresh fruits and vegetables can also become contaminated. Produce may pick up parasites from contaminated soil, water, animals, or handling. Rinsing fruits and vegetables thoroughly under running water can help remove dirt and some contaminants from their surfaces.
Raw or undercooked freshwater plants can carry parasites as well. Certain aquatic plants can become contaminated in environments where infected animals or contaminated water are present, making proper cleaning and cooking especially important.
