In two poultry-processing plants trials showed that cross-infection was only detectable when experimental infection with the indicator microorganism Escherichia coli K 12 was applied externally to the broiler chickens prior to scalding and plucking. When infection was applied internally, only a small degree of transmission was observed. The number of carcasses positive after cooling decreased in poultry-processing plant B compared with the situation after plucking, whereas this number was not affected to any appreciable extent in processing plant A.
