Two hours after death, the total number of bacterial colonies surged. What are the health risks of overnight crabs and dead crabs:

1. The growth of parasites and bacteria. We know that seafood such as crabs, fish and shrimps are rich in protein and are our favorite on the table. Usually when we go to food stalls or restaurants, we often have one or two plates of shrimp or crabs. However, after eating leftovers, some consumers take it home and eat it the next day in the spirit of not wasting it. In fact, this approach is wrong. Because crabs are immune to bacteria and parasites while alive, but once they die they become a breeding ground for parasites. Overnight, the bacteria have multiplied. Therefore, crabs that have been left overnight cannot be eaten.

2. Accumulation of toxins. Bacteria produce toxins, which are not conducive to the body's absorption and are not good for the body's health. Even after heating, some bacteria will still enter our intestines and stomach. In severe cases, it can cause food poisoning. Don't think that leaving it overnight will do nothing. In fact, the proliferation of bacteria is beyond your imagination. Especially the elderly and children, and pregnant women are more likely to get food poisoning when they accidentally eat such things. Food safety is something we all must pay attention to. Don’t put your body at risk just to not waste.

3. The higher the temperature, the histamine content of dead crabs will slowly increase, and the maximum score can reach 1400 ml. The amount of bacteria it carries is relatively high, and the toxins it produces are not easy to decompose. Severely ill patients may experience shock, nausea, vomiting, etc. The scariest thing is that these high temperatures cannot kill them. Crabs like to eat corrosive things such as dead shrimps and fish in the water. So the crab itself contains a lot of bacteria. Eating overnight crabs can cause intestinal inflammation. Therefore, for crabs, we should try to eat them while they are alive. Therefore, after cooking or overnight, if stored properly, it can be eaten again, but it cannot be cooked and used overnight.
