Antibiotic residue testing in a beef slaughterhouse.
On-site swab testing screened 487 bovine carcasses over 108 weeks. Twelve mature cows tested positive for antibiotic residues, highlighting a need for targeted screening in red meat plants.
Area of Science:
- Food safety and veterinary public health.
- Analytical chemistry and residue detection.
Background:
- Antibiotic residues in meat pose a public health risk.
- Effective screening methods are crucial for food safety compliance.
- On-premises testing offers rapid detection in processing environments.
Purpose of the Study:
- To evaluate the efficacy of on-premises swab testing for antibiotic residues in bovine carcasses.
- To determine the prevalence of antibiotic residues in a red meat processing plant.
- To identify potential sources or risk factors associated with positive findings.
Main Methods:
- Utilized on-premises swab testing for antibiotic residue detection.
- Conducted testing over a 108-week period in a Toronto red meat facility.
- Analyzed results from 487 bovine carcasses.
Main Results:
- Identified 12 positive bovine carcasses out of 487 tested.
- All positive cases were confirmed in mature cows.
- The study period spanned 108 weeks, indicating ongoing monitoring.
Conclusions:
- On-premises swab testing is a viable method for detecting antibiotic residues in slaughtered animals.
- Mature cows represent a higher risk group for antibiotic residues.
- Continuous monitoring is essential for maintaining food safety standards in meat production.
