Dishes, equipment, or surfaces that touch food were not properly washed, rinsed, and sanitized, or sanitizer was not at the right strength. Clean surfaces help stop germs from spreading to food.
Food came from an unapproved source, was missing required date marks or labels, or was past its use-by date. Knowing where food came from and how old it is helps prevent illness.

In plain English
Cleaning products, pesticides, or other chemicals were stored or labeled in a way that could let them get into food. This is serious because chemical contamination can make people sick quickly.
