The figures show that on average, across the market, 4.5% of chickens tested positive for the highest level of contamination, these are the chickens carrying more than 1,000 colony forming units per gram (cfu/g) of campylobacter. The figure testing positive at the highest level of contamination for the previous quarter (July-Sept 17) was 5.14%.
This reduction builds on the first set of results released by retailers in November 2017 (covering July-September) with the overall trend continuing to show a reduction in the highest level of contamination. This is consistent with previous research which shows a lower level of contamination over the cooler months of the year.
