The risk of cross-contamination and cross-contact are two things every food service establishment has to address every day. Bacteria are harmful to every patron, and food proteins are harmful to those with specific food allergies. Either way, allowing unintended food contact can be damaging to your business and your reputation. As a way to minimize the risk, use the Cambro One-Third Size Cover w/ Handle (30PPCH) on all of your third-size pans. This will keep ingredients from mixing and matching while in the ingredient rail.
