Abstract

Undertaken as an urgent risk assessment for Defra due to Salmonella Newport strains with penta resistance (ampicillin, chloramephenicol, sulfamethoxazole, streptomycin, tetracycline) with full/intermediate resistance to third generation cephalosporins being isolated in the US and Canada, but not in the UK.  The risk assessment is qualitative and assesses the risk of multidrug-resistant Salmonella Newport entering GB. The risk assessment assesses three risk questions, these are:

1) What is the risk of entry into Great Britain of multi-resistant Salmonella Newport through any source?

2) What is the risk of infection for GB livestock if the multidrug-resistant Salmonella Newport enters the country?

3) If a livestock species becomes infected with multi-drug resistant Salmonella Newport what is the risk of the infection becoming widespread?

From the risk assessment, it was concluded that MRSN was most likely to enter GB through humans, reptiles and livestock feed.  If the hazard were to enter GB, many routes were identified via which MRSN could infect livestock. In particular imported livestock, livestock feed, rural/farm cats/dogs, land & water have a potentially high risk of infecting livestock. Finally, it was concluded that is MRSN were to infect livestock, there was a high risk of the infection becoming widespread.
