The data set shows pesticide residues in different foods types, presented in 2 different table formats. The BNA format focusses on details of individual samples including brand name and origin and shows the pesticides detected if any. The SUM format focuses on the analysis and results across the set of samples, including detail of all the pesticides sought but not found.
As part of the programme each year 4 or 5 surveys are selected as “rolling reports” where one would expect there to be a higher rate of non-compliance to test more frequently. These results are initially published in the BNA format only and in due course included in the appropriate quarterly results.
