Even a single bite is harmful, yet many people eat it without hesitation.

Foodborne parasites pose a significant threat to food safety. These microscopic organisms, including amoebas, roundworms, hookworms, and tapeworms, can cause a variety of health problems once they enter the human body. Symptoms of a parasitic infection can include indigestion, gastrointestinal infections, anemia, and colitis. Although parasites are often invisible to the naked eye and odorless, they can be killed through proper hygiene and thorough cooking. To protect yourself and your loved ones, it is important to be aware of foods that may contain harmful parasites. This article highlights common foods that require special caution to avoid health risks from parasites.

Common foods that pose a risk of parasitic infections:

Undercooked meat (pork, beef and fish):

Raw or undercooked meat, especially pork, beef, and fish, can contain parasites such as tapeworms and roundworms. These parasites are transmitted when meat is not heated to the required core temperature. For example, undercooked pork can contain the  Trichinella  parasite, which causes trichinosis, while fish  can transmit Anisakis  worms, which can lead to anisakiasis. Because these parasites can cause serious health problems, it is essential to cook meat thoroughly.

Raw or undercooked shellfish:

Shellfish such as oysters, clams, and mussels are filter feeders that ingest parasites from contaminated water. These shellfish can harbor trematodes, a type of flatworm that can cause infections in humans. Consuming raw or undercooked shellfish significantly increases the risk of ingesting these harmful parasites and can have long-term health consequences.

Unwashed fruits and vegetables:

Fresh fruits and vegetables that are not thoroughly washed or peeled can contain parasites such as  Toxoplasma gondii  (the causative agent of toxoplasmosis) and  Giardia  (the causative agent of giardiasis). The soil in which fruits and vegetables grow can be contaminated with these parasites, and improper handling during transport or at the market can lead to infection. Thorough washing is therefore essential to reduce the risk of infection.
