1. The incidence of salmonellae was investigated in two batches of turkeys in the environmentally‐controlled houses and naturally ventilated pole‐barns of a commercial turkey enterprise. 2. The poults were free from contamination on arrival at the rearing house but were contaminated via the water supply from troughs which had been ineffectively fumigated. 3. Foodstuffs did not appear to be a source of contamination. 4. The spread of salmonellae in this turkey rearing enterprise was very similar to that in chicken rearing houses. |
