Abstract
The presently disclosed disinfection process for use in the processing of foodstuffs is designed as an intervention step in poultry processing to allow for continuous on-line processing of poultry carcasses that may have accidentally become contaminated during the evisceration process. Such on-line processing is designed to replace the need for off-line manual washing and cleaning of the contaminated carcasses. By eliminating such off-line manual washing, food safety will be enhanced due to the elimination of the physical handling of carcasses and the cross-contamination that may result from such physical handling. An additional benefit is that the production process will also be able to run with a reduced number of interruptions, which will result in a more efficient production process. The invention described herein is designed to employ the advantages of controlled chlorination at optimum pH levels, together with the proven effectiveness of increased contact time through the implementation of multiple stage treatment of the carcasses during slaughter, evisceration, washing and chilling. Additionally, an improved device and method are provided for effecting economic and efficient…
