Three commercial chicken examined for presence carcasses early (pre-scald) late (post-chill) process. Overall, percentage positive post-chill samples lower than previously reported earlier studies. Carcasses two maintained low at both sample sites. third plant accumulated significant increase pre-scald post-chill. later replaced evisceration equipment. A second evaluation, one month after placement equipment, revealed much processed
