scalding water → reduces → carcass contamination
temperature: 62 degrees C
“To reduce carcass contamination, it is recommended to ensure sufficiently high temperatures of scalding water (62 degrees C) and appropriate cleaning and disinfection of the polishing equipment at least once a day in order to reduce the level of carcass contamination and consequently the prevalence of Salmonella in pork.”
Campylobacter jejuni → was contaminated → after scalding and defeathering operations
source: contaminated birds and equipmentpercentage: 90 to 100%
“Twenty to 100% of live birds sampled contained C. jejuni on the skin but 90 to 100% were contaminated after scalding and defeathering operations from contaminated birds and equipment.”
scalding process without scalding water temperature control or improper scalding → increases the risk of → APC (odds ratio, OR = 4.84, 95% CI: 2.72-8.61), S. aureus (OR = 2.68, 95% CI: 1.29-5.55), Enterococcus spp. (OR = 3.38, 95% CI: 2.01-5.69), coliforms (OR = 3.01, 95% CI: 1.47-6.15), and E. coli (OR = 2.69, 95% CI: 1.58-4.56) contamination on meat samples
