Flocks were selected from a list of broiler chicken producers that volunteered in the OBFS. Equal numbers of farms were sampled from the 9 administrative districts of the Chicken Farmers of Ontario. One flock (defined as a group of birds hatched at the same time, delivered, and reared in the same barn or pen/floors) per farm (a registered establishment in Ontario and may have multiple barns in the premise) was sampled twice. Farm and hatchery level AMU and other farm-level operational and biosecurity information were collected for the CIPARS farm program using questionnaires administered by the participating veterinarian to the producer

various barn environment (e.g., clean litter and surface swabs in bird contact areas) and bird-associated samples (fecal samples, cloacal swabs, and meconium swabs from chick pads) were collected from single flocks on 90 commercial broiler chicken farms in Ontario between May 2003 and May 2004. The first sampling occurred on the day a new crop of chicks from the hatchery (chick placement) was delivered and then a second sampling was conducted 1 to 7 d before the flock was sent for slaughter (pre-harvest). In 2015, the CIPARS farm program collected samples using a similar methodology to that described. Samples were also collected at placement (environmental and chick pad swabs) and pre-harvest (fecal). In the CIPARS abattoir component, cecal samples were collected from clinically normal slaughtered birds
