They were also significantly higher in animal products seized from passengers travelling from Asia, with an average of 100,000 colony forming units (cfu) in products seized from passengers travelling from Asia compared to 4318 cfu for those travelling from Europe and 4889 cfu for those from South America. S aureus was detected in seven of the 322 products, while L monocytogenes was present in 11 samples. Salmonella was detected in a single product – a pig sausage being imported from Italy.
