Is it safe to eat a lump of Jamon that grew some mold?
Only for your information. The spanish ham can get moldy every time, because the curing process will not stop. And for sure you can eat after cleaning with oil. All this ham have mould but before it is sold they also clean it with oil or fat. Mostly the customer don't see it, but sometimes because of the humidity or if it is hot it can appear again, but it is not a problem for health (it is exactly the same as with the cheese.
