One of the most important safety tips to remember when working in the kitchen is to prevent cross contamination. This occurs when bacteria is transferred from one object to another. Failing to prevent this can be harmful to humans and may result in a foodborne illness.

Reusing a marinade can cause cross contamination because of the bacteria that may be present from having been in contact with the raw meat. The only way the marinade can be reused is to boil it thoroughly for use as a basting liquid or as part of a sauce for the meat.
