摘要

Bacterial culture of milk is one of the primary methods used to diagnose intramammary infections. Aseptic technique is thought to be vital when collecting milk samples for culture to minimize false positive results caused by bacteria on the teat end entering the sample during sample collection. Recommended practices for aseptically collecting milk include: gloved hands, pre-milking teat disinfection with a teat dip followed by drying with a single-use towel, scrubbing the teat end with gauze soaked in 70% alcohol, discarding a few streams of milk, and collecting the milk sample into a sterile vial1. While this approach is recommended, it has never been critically evaluated. Hence, the objective of this study was to determine if there were differences among teat end preparation techniques with regard to potential contamination of milk samples for culture.
