Knowledge and attitudes towards food safety among Canadian dairy producers

The Canadian dairy industry has recently begun implementing an on-farm food-safety (OFFS) program called Canadian Quality Milk (CQM). For CQM to be effective, producers should be familiar with food-safety hazards in their industry and have an adequate understanding of on-farm good production practices that are necessary to ensure safe food. To assess their knowledge and attitudes towards food safety, a postal questionnaire was administered to all (n = 10,474) Canadian dairy producers enrolled in dairy herd-improvement organizations in 2008. The response rate was 20.9% (2185/10,474). Most producers (88.7%) reported that they or their families consume unpasteurized milk from their bulk milk tanks and 36.3% indicated that consumers should be able to purchase unpasteurized milk in Canada. Producers who reported completion of a dairy-health management course (OR = 0.74, 95% CI: 0.60, 0.92) and participation in CQM (OR = 0.79, 95% CI: 0.64, 0.97) were less likely to support the availability of unpasteurized milk for consumers, while organic producers (OR = 2.10, 95% CI: 1.27, 3.47), younger producers (aged <30) and producers with smaller herds were more likely to favour this practice. Two-thirds of producers (66.7%) were concerned that antimicrobial resistance (AMR) might preclude successful treatment of sick cattle. Producers who completed a dairy-health management course (OR= 1.37, 95% CI: 1.11, 1.69), organic producers (OR = 2.00, 95% CI: 1.09, 3.69) and producers from Quebec compared to each other province were more likely to indicate concern about AMR. Most producers reported that Salmonella (74.2%) and Escherichia coli (73.0%) could be transmitted through contaminated beef or milk to humans, while most were not sure or did not think that Brucella (70.3%) and Cryptosporidium (88.5%) could be transmitted via these routes. Most producers did not perceive that any type of farm visitor has a high risk of introducing infectious agents into their herds. Producers rated veterinarians as very knowledgeable about OFFS (90.9% answered 4 or 5 on a five-point scale) and a favoured (73.1%) source of information about food safety. In contrast, only 13.2% and 30.2% of producers, respectively, indicated that consumers and government personnel are knowledgeable about OFFS. Targeted continuing education for dairy producers in Canada should address the major gaps in knowledge and attitudes towards food safety identified in this study, and veterinarians should be included as key knowledge-transfer informants.
