ABSTRACT

In modern agricultural practice, where herd and flock health is controlled and adequate records are maintained, detection of violative drug residues in the edible animal products is unlikely (1). Whenever they appear, violative residues are the result of inadvertent contamination due to management mistakes or to individual variations in animals’ ability to eliminate drugs. Therefore, factors of management and/or biological origin should always be considered by farmers, veterinarians, and regulatory agencies for a safe and wholesome food supply.
