After economic development caused water pollution, many people are worried about the problem of excessive heavy metals in prawns. When you see black shrimp heads, you will suspect that the heavy metal content is too high.

Water pollution will inevitably lead to pollution of aquatic products, so when shrimp hair turns black, many people subconsciously think that heavy metals exceed the standard.

However, there are many reasons for the black hair of shrimps. For example, the tyrosine in the shrimp body can produce melanin through the action of enzymes, thus making the shrimp hair black. The seaweed eaten by shrimps is stored in their internal organs. If the internal organs are ruptured, their heads will turn black. In other words, black shrimp hair does not mean excessive heavy metals. Moreover, with the development of the economy, there are also many shrimp farmers. As long as the farms are regular and the water quality and feed meet the standards, there will not be any big problems. If you are still worried, it is best to throw away the head.
