VPT 421: Veterinary Toxicology (2+0)

RESIDUE 

• Residue is defined as either the parent compound or a metabolite of the parent compound that may accumulate, deposit, or otherwise be stored within the cells, tissues, organs, or edible products (e.g., milk, eggs) of an animal following its use to prevent, control, or treat animal disease or to enhance production.
• The term also includes elements (such as metals) or other chemicals which may be present in food either through natural circumstances or as a consequence of man's industrial or agricultural activities.
• Chemical residues may be found in animal tissues, milk, or eggs following the administration of veterinary drugs and medicated premixes, the application of pesticides to animals, or the consumption of stock feeds previously treated with agricultural chemicals.
• Accidental exposure to chemicals in the environment can also result in tissue residues.
