The heart of the pig is black because it is moldy, there is a bad smell, you can not eat, there are a lot of bacteria, eat the loss ah.

Sometimes, when you eat bad meat, you don't necessarily get poisoned or get diarrhea, but those toxins will be deposited in your body, which is very bad for your body.

But if it's just a little bit sticky on the outside and hasn't changed in flavor, you can wash it a few more times, then cook it in boiling water, then fry it and eat it, so there's no problem.

But this is the internal blackening so it's better not to eat it.
