As a clear example of the direct link between compromised animal welfare and compromised food safety, and therefore a risk to human health and welfare, Cason et al. (2000) found that 75% of scald tank water samples in poultry slaughterhouses were salmonella positive. The salmonella bacteria was found to have been introduced through the excreta of still-live birds who entered the scald tank.

Government records indicate that each year MILLIONS of poultry are scalded to death or drowned in the scald tanks.

According to the Canadian Food Inspection Agency, each year approximately 13 million Canadians become sick due to foodborne illnesses. Salmonella is the leading cause.
By converting to Controlled-Atmosphere Killing, ALL birds would be dead by the time they reach the scald bath reducing the risk of salmonella contamination, and directly reducing the numbers of Canadians sickened by foodborne illnesses.
