Salmonella Virchow in a Chicken-packing Station and Associated Rearing Units

Abstract

In tracing the source of an outbreak of food-poisoning with Salmonella virchow a chicken-packing station and associated rearing farms were investigated. The serotype was found in chickens in 9 of the 14 rearing farms investigated and in the hatchery, but not in the breeding flocks supplying the hatchery. Several personnel on the farms were affected. The infection was most likely to have been introduced by contaminated feeding-stuffs.
