WINE GUMS THAT HAVE BLISTERS

Was eating a pack of Maynards wine gums when i came across a funny tasting gum, so i spat it out and when i looked at it i was horrified to see it looked disgusting like it had two blisters on opposite sides of the sweet. i would not be surprised if it was picked off the warehouse floor and just chucked in the packet. Im truly disgusted because this is something i consume regularly, i don't want to fall sick one day and later find out that its because of dirty wine gums.
