Again this is showing good reductions of 1 log10 in surface contaminations of Campylobacter. In the US and New Zealand, Campylobacter is well-controlled through the use of 20 to 30 ppm chlorine washes during processing. Due to concerns over the carcinogenic residues, this is not permitted in the EU, making Campylobacter more of a European problem.
While in-plant interventions may reduce the Campylobacter load sufficiently to meet FSA/EFSA standards, direct poultry infection still remains much lower than indirect poultry contamination. Efforts to reduce the environmental risks at production or farm level will be required. Three major ways of controlling Campylobacter include: improving on-farm biosecurity, stopping thinning of flocks and reducing the slaughter age to 28 days.
