Not necessarily. Lobster tail generally refers to the tail of the crayfish, which may have parasites, because the crayfish grow in aquatic ecosystems, with a variety of other organisms *** with life, and the environment may be affected by pollution, which makes the crayfish is very easy to become a host for a number of parasites, such as nematodes, sucking worms and so on. Therefore, there is a possibility that the tail of the crayfish may harbor parasites. After purchasing them at home, consider treating them with an initial soak in salt water. This not only cleans the crayfish tails, but also helps to expel some of the parasites carried. Additionally, ensuring that the crayfish tails are fully cooked during the cooking process and avoiding half-cooked crayfish tails can go a long way towards avoiding the associated health risks.
