Question

contaminated by foreign substances occurs when
what’s on my food?
milk products are kept at room temperature
foods are not cooked at proper temperatures
chemicals are not rinsed from foods before processing
a sticky slime appears on the surface.

Explanation:

Contamination by foreign substances in food can occur when chemicals like pesticides are not rinsed off before processing. Keeping milk products at room - temperature leads to spoilage due to bacteria growth rather than foreign - substance contamination. Not cooking foods at proper temperatures can cause under - cooking or foodborne illness from bacteria, not foreign - substance contamination. A sticky slime on the surface is often a sign of microbial growth, not foreign - substance contamination.

Answer:

Chemicals are not rinsed from foods before processing
