Wood ear fungus changes when soaked in water for a long time

The black fungus we buy on the market is already dried, if you want to use it to cook, you need to treat it by soaking. If the eardrum soaked for too long, metamorphosis appears, it will produce a bacterium Pseudomonas syringae, which will produce a toxin called BA.

Most patients develop symptoms suddenly from half a day to a day. At first, there will be symptoms such as nausea, vomiting, diarrhea and then onset of liver swelling and even liver necrosis.
