What is tolerance in regards to residues?
The maximum legally allowable level or concentration of a drug or chemical in a food product at the time milk or eggs are marketed, or the animal is slaughtered

The guide for deciding whether or not to prosecute
What is a residue?
Any substance that is foreign to the body - in our case, we are interested in residues that are left after drug administration
What is a violative resiude?
A drug residue found to be at or above the regulatory limit in a tissue, milk, or eggs
When can there be a legally acceptable residues of drugs in edible tissues, eggs, or milk at slaughter?
IF there is an established tolerance in tissues/milk for that animal species
T/F: For drugs without a label and corresponding tolerance in a species, then any residue detected is violative.
True
