ABSTRACT
This chapter focuses upon the sources of chemicals and toxins that commonly cause violative residues in livestock, and recommended procedures for decontamination of exposed animals. Suggestions are presented for the prevention of such residues through feeding and management techniques. Case histories of two actual incidents of livestock contamination are presented, together with the methods employed for decontamination of the herds. Chronic exposures may be more difficult to diagnose than acute ones. Appropriate samplings of blood, urine and feces, and biopsies of fat and other tissues may be indicated. Animals that have been contaminated by lipid soluble compounds, such as chlorinated pesticides and some industrial chemicals, may have violative residues in their body fat. Decontamination of the animal can be accelerated by promoting the loss of body fat through limited feeding, or increased butterfat production in milk, depending upon the management circumstances.
