If you find a worm in your fish, don’t panic. It’s more common than you might think, and there are steps you can take to ensure your meal is safe. Identifying and properly handling parasitic worms can prevent health risks and ensure a delicious dining experience.
What Should You Do If You Find a Worm in Your Fish?
Discovering a worm in your fish can be unsettling, but it’s important to know that this occurrence is not unusual. Fish, like many animals, can host parasites. Here’s what you should do:
