Can You Get Worms from Sushi
Yes, it is possible to get worms from sushi if the fish contains parasitic larvae. The most common concern is Anisakis, a type of roundworm found in marine fish and squid. When people eat raw or undercooked infected fish, the larvae can attach to the stomach or intestinal lining, causing discomfort and digestive symptoms.
How Parasites End Up in Sushi Fish
Fish become infected when they consume smaller organisms carrying parasite larvae in the ocean. Wild-caught fish are more likely to carry parasites than farmed fish in controlled environments. Freezing fish at specific temperatures for a set time can kill many parasites, which is why regulations often require raw fish to be frozen before serving in sushi.
How to Reduce Risk When Eating Sushi
Choose reputable restaurants that follow food safety guidelines and use fish handled by trained professionals. Freezing requirements, proper handling, and sourcing from trusted suppliers help lower the chance of parasites. If you are concerned, you can ask whether the fish was previously frozen or choose cooked sushi options instead.
