Removing faecal contamination of broilers by spray-cleaning during evisceration
British Poultry Science
|March 1, 1980
Summary
Spray-cleaning broiler carcasses during evisceration prevents fecal contamination. Continuous cleaning is more effective than end-process cleaning for reducing Enterobacteriaceae and Salmonella.
Area of Science:
- Food safety
- Microbiology
- Poultry processing
Background:
- Evisceration of broiler carcasses can lead to fecal contamination.
- Enterobacteriaceae, including Salmonella, are key indicators of contamination.
Purpose of the Study:
- To evaluate the effectiveness of spray-cleaning during evisceration.
- To compare continuous versus end-process cleaning methods.
Main Methods:
- Broiler carcasses were subjected to evisceration.
- Spray-cleaning interventions were applied at different stages.
- Enterobacteriaceae and Salmonella levels were monitored.
Main Results:
- Fecal contamination during evisceration increased Enterobacteriaceae and Salmonella.
- Continuous spray-cleaning completely prevented this increase.
- End-process cleaning did not reduce bacterial numbers to initial levels.
Conclusions:
- Continuous spray-cleaning during broiler carcass evisceration is highly effective.
- This method prevents microbial contamination and enhances food safety.
- Intermittent cleaning is less effective in controlling bacterial load.
