Non-typhoidal salmonella contamination along the pork value chain in a rural East African setting: a cross-sectional study

Trans R Soc Trop Med Hyg. 2023 Nov 3;117(11):811-813. doi: 10.1093/trstmh/trad046.

Abstract

Background: Non-typhoidal Salmonella (NTS) is a serious foodborne pathogen that has previously been isolated from pigs presented for slaughter in a rural pork value chain in western Kenya.

Methods: To understand varying NTS contamination along the value chain we assessed prevalence at slaughter, transport and retail. Suspect isolates from culture were confirmed using matrix-assisted laser desorption-ionization time of flight mass spectrometry.

Results: Prevalence on pig carcasses, meat transportation containers, retailed raw and cooked pork and accompanying side salads was 18.1%, 23.9%, 28.0%, 1.9% and 8.6%, respectively.

Conclusion: NTS contamination is propagated along the pork value chain in rural western Kenya, demonstrating the need for improved hygiene measures to prevent human exposure.

Keywords: food safety; foodborne disease; non-typhoidal Salmonella; pork meat; salmonellosis.
