Summary
Transport and holding significantly increase Campylobacter spp. contamination on chicken carcasses. This study reveals higher bacterial loads post-transport, impacting poultry food safety.
Area of Science:
- Food Microbiology
- Poultry Science
- Food Safety
Background:
- Campylobacter spp. are a major cause of foodborne illness.
- Poultry carcasses are a primary source of human Campylobacter infections.
- Understanding contamination sources is crucial for public health.
Purpose of the Study:
- To investigate Campylobacter spp. colonization in chicken ceca.
- To assess Campylobacter spp. contamination on chicken carcasses.
- To determine the impact of transport and holding on bacterial levels.
Main Methods:
- Sampling of chicken ceca and carcasses from broiler farms.
- Analysis of bacterial loads before and after transport/holding.
- Comparison of contamination levels pre- and post-commercial transport.
Main Results:
- Campylobacter spp. were found in ceca from 90% of farms sampled.
- Cecal colonization levels ranged from 10(4.11) to 10(7.28) cfu/g.
- Carcass contamination significantly increased after transport, from 10(3.66) to 10(7.11) cfu/carcass.
Conclusions:
- Transport and holding periods contribute to increased Campylobacter spp. contamination on poultry carcasses.
- Pre-processing transport is a significant factor in final carcass contamination levels.
- Findings highlight the need for interventions during transport to improve poultry food safety.
