The residue concentration of a pesticide on food or feed judged to be safe for human use is referred to as?

The term that refers to the residue concentration of a pesticide on food or feed that is deemed safe for human consumption is known as "tolerance." Tolerances are specific limits set by regulatory agencies, such as the Environmental Protection Agency (EPA) in the United States, which establish the maximum allowable levels of pesticide residues that can remain on food products. This concept is crucial for ensuring public safety and maintaining acceptable levels of pesticides in the food supply.

The other terms provided do not accurately describe this regulatory standard. "Residue" generally refers to the remaining pesticide on the food or feed but does not imply safety or regulation. The term "amount" is too vague and does not capture the regulatory framework involved in setting safe levels for pesticide residues. Therefore, "tolerance" is the correct and appropriate term used in this context.
