Lobster's head can't be eaten. Lobster has a certain ability to enrich heavy metals, mostly concentrated in shrimp gills, internal organs and shrimp shells, while shrimp internal organs and shrimp gills are concentrated in the head, so eating lobster's head may cause excessive intake of heavy metals, thus causing cancer.

There are not only many formed eggs in the head of shrimp, but also many other lobsters' own garbage toxins. For these reasons, eating the head of lobster may cause allergies and acute gastroenteritis, which may lead to paragonimiasis.

If the growth environment of lobster is not good, the shrimp head will be polluted by heavy metals in the environment and parasites in the water environment, and become the host of parasites such as schistosomiasis and clonorchiasis. In a word, shrimp head is the place where toxins are absorbed and accumulated the most, and it is also the part where pathogens and parasites are most likely to accumulate.

Extended data

The white line of shrimp head is not a parasite, but the gonad of male shrimp-vas deferens. The immature vas deferens are colorless and transparent, and the mature male shrimp is milky white. At this time, it is the breeding season of shrimp, so it is not surprising that male shrimp contains vas deferens. The main component of the gonad of shrimp is protein, which is completely edible.

Generally speaking, the immature testis is colorless and transparent, and it is milky white after maturity, which can be said to be equivalent to crab paste, rich in cholesterol and protein. This white line is not only found in prawns, but also in shrimps and lobsters. Moreover, it is thicker and cannot be a parasite at all.
