Decontamination of chicken and turkey cut parts

More recently, this technology has been constructed for continuous decontamination of chicken and turkey cut parts with capacities ranging from 1-2 tons per hour. Results showed more than 85% reduction in Salmonella and Enterobacteriaceae on turkey breast filets in an unpublished study. On freshly slaughtered skin-on cuts, the combined process of steam and ultrasound reaches higher reductions of >95%. The process can be applied just before packaging to benefit from possible synergistic effect from the thermal treatment followed by modified air packaging (MAP). The fast process time using affordable steam generated through maintenance-free nozzles may be a profitable solution for companies looking to avoid economic losses through product recalls and reduced shelf-life.

Over the past few years, six full-scale installations for treating whole carcasses have been introduced to European slaughterhouses with capacities from 11-15,000 birds/h. To this date, millions of freshly slaughtered broilers have been processed through a chamber of steam and ultrasound and no visible or thermally changes have been detected. The combined process of steam and ultrasound have been evaluated before, showing more than 90-95% reduction in pathogens such as Campylobacter and TVC (reference).
