The
inconsistence of prevalence from different countries might be
biased because of different stages where they sampled, varied
compositions of sample types and detection methods. Using the
prevalence of Salmonella contamination in chicken carcasses as the
worst case for all chicken and their products at the retail level, the
present study showed 41.6% of chicken carcasses were contaminated
with Salmonella at the retail level whichwas lower than what
Yang had observed (52.2%, N ¼ 1152) using chicken carcasses as
well (Yang et al., 2011).
