Drinking Pipes and Nipple Drinkers in Pig Abattoir Lairage Pens-A Source of Zoonotic Pathogens as a Hazard to Meat Safety.

The water distribution system in the lairage pens of abattoirs could act as a route of contamination for produced meat. In this study, biofilm formation and the occurrence of specific pathogens in drinking equipment was investigated in different lairage pens in a German commercial pig abattoir. Samples of the water and the drinkers in different locations were microbiologically cultivated and examined.
