Abstract
Mobile slaughter is increasingly used to improve animal welfare by reducing transport stress, but concerns remain about microbiological contamination due to delayed evisceration. This study assessed internal abdominal cavity surfaces of 58 cattle carcasses under routine mobile slaughter conditions in Germany by swabbing and analyzing total viable count (TVC) and the presence of Escherichia (E.) coli. Of 99 swabs, 46.5% exceeded the limit of quantification with a mean TVC of 2.42 log10 CFU/100 cm2, while E. coli was detected in only a single non-quantifiable case. No significant correlation was identified between the bacterial load and the bleeding-to-sampling interval (p = 0.76), which predominantly ranged up to 2 h. These results indicate that delayed evisceration within this timeframe does not increase microbiological contamination of internal carcass surfaces. The findings support the hygienic safety of mobile slaughter practices under the conditions studied and provide data to inform regulatory guidelines regarding evisceration timing.
期刊介绍:
The JCF publishes peer-reviewed original Research Articles and Opinions that are of direct importance to Food and Feed Safety. This includes Food Packaging, Consumer Products as well as Plant Protection Products, Food Microbiology, Veterinary Drugs, Animal Welfare and Genetic Engineering.
All peer-reviewed articles that are published should be devoted to improve Consumer Health Protection. Reviews and discussions are welcomed that address legal and/or regulatory decisions with respect to risk assessment and management of Food and Feed Safety issues on a scientific basis. It addresses an international readership of scientists, risk assessors and managers, and other professionals active in the field of Food and Feed Safety and Consumer Health Protection.
Manuscripts – preferably written in English but also in German – are published as Research Articles, Reviews, Methods and Short Communications and should cover aspects including, but not limited to:
· Factors influencing Food and Feed Safety
· Factors influencing Consumer Health Protection
· Factors influencing Consumer Behavior
· Exposure science related to Risk Assessment and Risk Management
· Regulatory aspects related to Food and Feed Safety, Food Packaging, Consumer Products, Plant Protection Products, Food Microbiology, Veterinary Drugs, Animal Welfare and Genetic Engineering
· Analytical methods and method validation related to food control and food processing.
The JCF also presents important News, as well as Announcements and Reports about administrative surveillance.
