Can you still eat Chinese chestnut after it has sprouted?

Aflatoxin is a highly toxic metabolite produced by Aspergillus flavus and parasitic Aspergillus flavus, as well as carcinogenic, teratogenic and mutagenic effects. It can mainly cause liver cancer, but also bone cancer, kidney cancer, rectal cancer, breast cancer and so on. Aflatoxin is one of the strongest chemical carcinogens found so far.

Aspergillus flavus widely exists in soil. Toxins are produced during mycelial growth, and spores can spread into the air. Under suitable conditions, Aspergillus flavus can infect suitable parasites and produce aflatoxins. Some people may think that high-temperature sterilization is not enough?
