US FDA Issues Amendment Correcting the Usage of Lincomycin in Feed & Water

The U.S. Food and Drug Administration (FDA) Center for Veterinary Medicine officially enacted a strict technical correction amendment. The final rule resolves a series of clerical errors regarding the dual administration of Lincomycin in food-producing animals.

The rule outlines strict boundaries for field veterinarians to prevent gastrointestinal toxicity and product cross-over:

• For Swine Operations: Lincomycin Type A medicated water articles are strictly indicated for swine dysentery (“bloody scours”). The FDA explicitly warns that water treatments must never be run simultaneously with medicated feed blocks. Furthermore, access is rigidly barred from horses, rabbits, and ruminants due to fatal cecal and gastrointestinal sensitivities.

• For Broiler Integrators: A strict 7-day dosing sequence is mandated for necrotic enteritis. The FDA reiterated that the drug remains entirely unapproved for laying hens or breeding chickens to eliminate the risk of illegal residue pathways in human egg grids.
