Summary and Implications
Prevention of drug residues in milk is a daily endeavor on dairy farms. There is increasing scrutiny from the public and government when it comes to drug residues in milk. Drug residues can result from simple human errors, disease processes not allowing for normal clearance of a drug, or malicious activity. The testing methodologies used to detect drug residues have become more sensitive with many tests available that can detect drug levels below ten parts per billion (ppb).
