What is particularly serious is that some mycotoxins are carcinogenic, so even after the rotten part has been removed, the remaining fruit should not be eaten.
For various reasons, improperly stored fruit often rots after being purchased. Consequently, some people will cut out the rotten part and eat the remaining, unaffected portion. Some street vendors also often sell partially rotten fruit at a low price. Many people believe that removing the rotten part and eating the rest poses no health risk. In fact, this is a misconception.
This is because even though the remaining part is not rotten, it has been largely infiltrated by various harmful substances produced during microbial metabolism. Especially when the proliferation of fungi on the fruit accelerates, a considerable number of fungi produce toxic substances during their reproduction. These toxic substances can diffuse from the rotten part to the unrotten part through the fruit juice, causing the unrotten part to also contain microbial metabolites, particularly mycotoxins, just like the rotten part.
