Aderounmu (1966) showed that 12 species were found in wild trout and 7 species were found in hatchery-reared trout.
When several of these issues were addressed through public health interventions, the number of human cases associated with birds from the implicated hatchery dropped dramatically in 2000.
Campylobacter was not found in the hatchery, 1-day-old chicks or in the rearing house before the arrival of the chicks.
In the hatchery and after transport of the 1-day-old chicks, salmonella was isolated from only one and two flocks, respectively.
First, 1999 was a record sales year for this hatchery.
At vertical introduction, the infection enters the flock via the hatchery.
For this, 18 individual broiler flocks were intensively studied from the hatchery to the slaughterhouse.
Who ever made an effort to follow individual birds throughout their odyssey from hatchery through shed to slaughterhouse?
