Carcass_Cow2_MPSSlaughtered carcasses are sprayed with hot water after dehiding and after evisceration to clean the surface of the carcass. The carcass is hung from the overhead conveyor and an operator uses a high-pressure sprayer to wash the surface of the carcass. Water must be at least 170°F and may contain acetic or lactic acid to help kill all microorganisms. Most facilities pretreat the wastewater before discharging the water to the public sewer system. Due to higher labor input, manual hot water cleaning is used in smaller slaughterhouse operations.
