Abstract
Recovery of pathogens from breast meat, thigh meat and skin from scalded, defeathered but uneviscerated broiler carcasses with and without spray washing was compared to recovery from breast meat, thigh meat and skin from fully processed, chilled carcasses (controls). The incidence of coagulase-positive staphylococci was not significantly different on meat and skin from both uneviscerated carcasses with and without a spray washing compared to meat and skin from fully processed carcasses. The incidence of Clostridium perfringens was not significantly different on skin, breast and thigh meat for any of the sampling sources except that incidence on meat from control breasts was lower than on breast meat from uneviscerated carcasses without spray-washing; and incidence on meat from control thighs was lower than on meat from spray-washed, uneviscerated carcasses. Salmonella incidence was higher on both breast and thigh meat from fully processed control carcasses than from uneviscerated unwashed carcasses. When uneviscerated carcasses were spray-washed after defeathering, the incidence of Salmonella was not significantly different on breast meat, and significantly lower on thigh meat than on these meats from fully processed control carcasses. Skin from fully processed control carcasses had a higher incidence of Salmonella than did skin from uneviscerated, unwashed carcasses, but not skin from uneviscerated, spray-washed carcasses. Reducing the number of stages of processing significantly reduced the incidence of Salmonella but not of coagulase-positive staphylococci or Clostridium perfringens.
