The study included a total of 7 different hatcheries, 17 different poultry houses on 17 different farms and 9 different slaughterhouses.
For this purpose, 18 individual broiler flocks were intensively studied from hatchery to slaughterhouse.
The implicated hatchery was a small, family business, primarily a mail-order supplier to farm and feed stores and private individuals.
Legislation governs only hatcheries and breeder flocks and there is neither legislation nor funding for broiler surveillance.
No environmental studies of source hatcheries were completed.
There was no common feed source for the young birds at the hatchery or after they were purchased.
Contamination of the 1day-old chicks (' hatchery '), their transport, and the contamination of the fresh feed did not appear to have a significant influence.
Who ever made an effort to follow individual birds throughout their odyssey from hatchery through shed to slaughterhouse?
