Chocolate, because of its low water activity, prevents the growth of microbial hazards and prevents microbial spoilage problems. However, there is potential for Salmonella contamination from added ingredients such as cocoa, coconut, milk powder, and egg albumen, all of which may contain Salmonella. The addition of nuts, peanuts and cocoa may also introduce mycotoxins (e.g. aflatoxins and ochratoxin A). In this generic model, only almonds have been added to the chocolate.
