What is chemical contamination or pollution?

Chemical contaminants are chemicals toxic to plants and animals in waterways. The phrase ‘chemical contamination’ is used to indicate situations where chemicals are either present where they shouldn’t be, or are at higher concentrations than they would naturally have occurred.

What is a chemical contaminant?

Contaminants are chemical substances that have not been intentionally added to food or feed. These substances may be present in food as a result of the various stages of its production, processing, or transport. They also might result from environmental contamination.

What are the differences between biological chemical and physical contamination?

It’s important to know how food can become contaminated so that you can protect against it. Chemical contamination refers to food that has been contaminated by some type of chemical substance. … Physical contamination refers to food that has been contaminated by a foreign object at some stage of the production process.
