The influence of scald water pH on the death rates ofSalmonella typhimuriumand other bacteria attached to chicken skin

Abstract
Factory trials where scald tank water was maintained at pH 9.0 .+-. 0.2 showed that compared with the usual system of scalding when the water is at pH 6.0 for much of the working day the bacterial counts on carcasses post scalding and plucking were significantly lower. In laboratory experiments, attached S. typhimurium and the naturally occurring skin flora were killed significantly more quickly in water at pH 9.0 .+-. 0.2.
