Food safety criteria for Listeria monocytogenes in ready-to-eat (RTE) foods have been applied from 2006 onwards (Commission Regulation (EC) 2073/2005). Still, human invasive listeriosis was reported to increase over the period 2009-2013 European Union and Economic Area (EU/EEA). Time series analysis 2008-2015 EU/EEA indicated an increasing trend of monthly notified incidence rate confirmed 75 age groups female group between 25 44 years old (probably related pregnancies).

EFSA and EMA have jointly reviewed measures taken in the EU to reduce need for use of antimicrobials food-producing animals, resultant impacts on antimicrobial resistance (AMR). Reduction strategies been implemented successfully some Member States. Such include national reduction targets, benchmarking use, controls prescribing restrictions specific critically important antimicrobials, together with improvements animal husbandry disease prevention control measures.

African swine fever (ASF) is currently spreading westwards throughout Europe and eastwards into China, with cases occurring in both wild boar domestic pigs. A generic risk assessment framework used to determine the probability of first infection ASF virus (ASFV) at a fine spatial scale across European Union Member States. The aims assist managers their surveillance intervention activities. Performing allows for hot-spot surveillance, which can aid by directing or resources those areas...

Machine learning (ML) is an approach to artificial intelligence characterised by the use of algorithms that improve their own performance at a given task (e.g. classification or prediction) based on data and without being explicitly fully instructed how achieve this. Surveillance systems for animal zoonotic diseases depend upon effective completion broad range tasks, some them amenable ML algorithms. As in other fields, veterinary public health surveillance has greatly expanded recent years....

The number of West Nile virus (WNV)-infected mosquitoes aboard aircraft from the United States that arrive in Kingdom each summer was determined using a quantitative risk assessment. In worst-case scenario, when WNV levels are high (at epidemic levels) probability at least one WNV-infected mosquito being introduced into predicted to be 0.99. During these periods, mean 5.2 infected were estimated flights during May October, with 90% certainty exact value lies between and ten mosquitoes....
