National Monitoring Plan for POAO: Data Analysis Report 2022-23 - Sampling for microbiological contamination
A summary of the microbiological contamination sampling results of imported products of animal origin (POAO) undertaken at UK Border Inspection Posts (BCPs), under the UK’s National Monitoring Plan (NMP), between April 2022 and March 2023.
There were 674 samples from 23 countries taken and checked for the presence of microbiological contamination. There were twenty three non-compliant results identified: one each for Aerobic colony count at 30 ºC for 48h, Coagulase Positive Staphylococci, 5 each for Enterobacteriaceae & Eschericia coli, 3 for Eschericia coli (STEC), one each for Listeria monocytogenes, Listeria species (total), Salmonella species, 3 for Salmonella spp., one for Staphylococcus coagulase + and one for Vibrio species, all from Australia, Chile, China, India, New Zealand, Pakistan, Thailand, Ukraine and Vietnam.
The greatest number of microbiological samples were taken from Thailand (192 or 28%), China (114 or 17%), Vietnam (69 or 10%), Indonesia (57 or 8%), Chile (45 or 7%), India (38 or 6%), New Zealand (28 or 4%), Ukraine (10 or 3%) Serbia (19 or 3%), Brazil (17 or 3%), Bangladesh (16 or 2%), Myanmar (16 or 2%) and Australia (13 or 2%). Countries marked with an asterisk in the table are shown together as ‘other’ on the chart.
