Hygiene isn’t just about washing visible dirt off food. Some foods contain invisible “dirt” in the form of parasites, which cannot be removed simply by rinsing with water, and in some cases, even cooking may not completely eliminate them. Consuming these parasites can pose serious health risks.

Although people today are more conscious of food safety and hygiene, many still give in to the temptation of delicious dishes or are unaware of which foods carry parasites. Below are five foods known to contain parasites, so it’s best to avoid them whenever possible.

1. Sashimi

Among all parasite-prone foods, sashimi ranks at the top. Unlike other foods where cooking can destroy some parasites, sashimi is eaten raw, making it a high-risk dish. While its fresh, delicate taste is loved by many, it can harbor liver flukes, which pose serious health risks if not properly cleaned.

2. Snails

Snails are a popular street food, known for their chewy texture and affordability, often enjoyed at late-night barbecues. However, due to their unique structure, they are difficult to clean thoroughly. The only way to remove parasites in snails is through high temperatures. Unfortunately, many restaurants stir-fry them for a short time, which isn’t enough to eliminate all parasites.

If you really want to eat snails, it’s best to buy and cook them yourself. This way, you can ensure they are cleaned properly and cooked at high temperatures for a longer duration, which significantly reduces the risk of consuming parasites. If you’re unsure how to clean or cook them safely, it’s better to avoid them altogether—your health is more important than taste.

3. Water Chestnuts

Many people don’t realize that water chestnuts can also carry parasites. One such parasite is known as the ginger bug. To safely consume water chestnuts, they must be thoroughly washed, peeled, and cooked at high temperatures before eating.

4. Steak

Western cuisine often serves steak at varying levels of doneness, with many preferring medium rare for its texture and flavor. However, a steak that is still red in the center may not have reached a temperature high enough to kill parasites. Eating undercooked steak increases the risk of ingesting harmful organisms.

When it comes to food safety, it’s crucial to be mindful of potential risks. While these foods may be tempting, proper preparation and cooking methods are essential to avoid health hazards.
