Evaluation of risks of violative milk residues following extra label topical administration of tetracycline for digital dermatitis in dairy cattle.


Team: Johnson R., Cramer, G

Funding Source: DFO, Vetoquinol, OMAFRA Food Safety Research Program

Project Time Frame: 2013-2015

This study will evaluate the depletion (withdrawal time) of milk tetracycline levels to the accepted MRL, when tetracycline is applied topically in an extra label manner as either a paste or in powdered form (under bandage wrap) at doses ranging from 2 grams to 25 grams to dairy cattle diagnosed with severe digital dermatitis. Data collection and analysis is complete.
