Unwillingly I deleted the answer, but basically a lot of carcinogenic things are used in the industry, like for example dyes, the caramel dyes used in Coca Cola, but be calm, as I said, it's a small amount, very hard to have any serious side effects. And I said about cancer exactly by the amount, maybe you put a dangerous enough amount to get sick and not kill.
Why would they do that i mean use it in presercat
I mean use it in preserving if it's carcinogenic
