Enterobacteriaceae associated with meats and meat handling
Applied and Environmental Microbiology
|April 1, 1981
Summary
Meat-handling surfaces are a primary source of Enterobacteriaceae contamination in meats. Klebsiella pneumoniae may indicate poor hygiene at retail meat facilities.
Area of Science:
- Food safety
- Microbiology
- Public health
Background:
- Enterobacteriaceae are common bacteria found in food products.
- Understanding the sources of contamination is crucial for food safety.
Purpose of the Study:
- To investigate the source of Enterobacteriaceae contamination on meats.
- To identify specific bacterial species associated with meat handling and their implications for hygiene.
Main Methods:
- Isolation and identification of 2,343 Enterobacteriaceae from meat samples and work surfaces.
- Sampling conducted at packing plants and retail facilities.
- Analysis of bacterial prevalence across different stages of meat handling.
Main Results:
- Meat-handling work surfaces were identified as a significant source of Enterobacteriaceae.
- Escherichia coli biotype I and Serratia liquefaciens were ubiquitous throughout the meat-handling system.
- Klebsiella pneumoniae was prevalent in packing plants but scarce at retail, suggesting it as a potential hygiene indicator.
Conclusions:
- Meat-handling surfaces are a key reservoir for Enterobacteriaceae.
- Certain species like E. coli and S. liquefaciens are consistently present, while K. pneumoniae may signal inadequate hygiene practices at the retail level.
