Higher line speed in young chicken slaughter establishments does not predict increased Salmonella contamination risks.

ABSTRACT: Do faster slaughter line speeds for young chickens increase risk of Salmonella contamination? We analyze data collected in 2018-2019 from 97 slaughter establishments processing young chickens to examine the extent to which differences in slaughter line speeds across establishments operating under the same inspection system explain observed differences in their microbial quality, specifically frequencies of positive Salmonella samples. A variety of off-the-shelf statistical and machine learning techniques applied to the data to identify and visualize correlations and potential causal relationships among variables showed that the presence of Salmonella or other indicators of process control, such as noncompliance records for regulations associated with process control and food safety, are no
