5 NEW ASPECTS (AREAS BROUGHT INTO FOCUS) Collaboration and cross-verification with DG SANTE (D4, G4 and G2): reporting on Salmonella serovars (target) reporting on Salmonella in pig meat according to Regulation 854/2004 bovine tuberculosis Expert contributions: Salmonella Listeria STEC Trichinella, Echinococcus Food-borne outbreaks 5

6 HUMAN ZOONOSES CASES IN EU, 2015 Reported notification rates of zoonoses in confirmed human cases in EU,

7 SALMONELLA IN HUMANS, ANIMALS AND FOOD, EU, The number of cases of salmonellosis increased slightly from 92,007 in 2014 to 94,625 in However, the long-term trend ( ) is still declining. Most Member States met their Salmonella reduction targets for poultry populations. Salmonella is mainly found in meat (poultry) intended to be cooked before consumption 7

9 SALMONELLA IN PIG CARCASES, AT SLAUGHTER, 2015 (REG. 854/2004) Country Description Sample origin Sampling unit Sample weight Tested Positive Percent positive Croatia Survey slaughter batch Slovakia food sample - carcase swabs, Control and Slovakia batch 100 Square centimetre eradication programmes United Kingdom animal sample, Monitoring United Kingdom slaughter batch 1000 Square centimetre Slaughter batch Batch Total (MSs) Croatia, Slovenia and the United Kingdom reported on sampling investigations by the Competent Authority. A total of 7,448 samples were collected. Overall, 1.24% of the units were Salmonella-positive. 9

Out of 25,730 samples collected, 5.1% units were Salmonella-positive, which is higher compared to the monitoring results for Salmonella on pig carcases based on sampling investigations by the Competent Authority. However, these results are based on the reports of only few MS and may not be representative yet for the EU. 10

11 TARGET SALMONELLA SEROVARS IN POULTRY, EU, Since the implementation of the National Salmonella Control Programs since many years, a statistically significant declining trend in the EU-level prevalence of Salmonella target serovars-positive flocks was observed for all categories with the exception of breeding turkey flocks 11

12 SALMONELLA IN POULTRY, EU, 2015 Breeding flocks: BG and PL did not meet the Salmonella reduction target and the EU prevalence for the five target serovars was 0.34% (Salmonella spp. 1.42%). Flocks of laying hens: PL did not meet the relative Salmonella reduction target. The EU prevalence for the two target serovars (S. Enteritidis and S. Typhimurium) was 1.0% (Salmonella spp. 2.7%). Broiler flocks: LU and CZ did not meet the Salmonella reduction target before slaughter. The EU prevalence for the two target serovars was 0.26% (Salmonella spp. 2.2%). Turkey breeding flocks: all 14 MS which reported data, met the target, with an overall prevalence of 0.4% for the two target serovars (Salmonella spp. 1.41%). Fattening turkey flocks: BE and GR did not meet the Salmonella reduction target before slaughter. At the EU level, 0.34% of the fattening turkey flocks were infected with the two target serovars (Salmonella spp. 3.6%). 12

19 FBO BY CAUSATIVE AGENT, The total number of Salmonella outbreaks within the EU decreased by 40.6% between 2010 (1,604 food-borne outbreaks) and 2015 (953 outbreaks). 19

20 SALMONELLA FBO In 2015, 23 MS reported a total of 953 food-borne outbreaks caused by Salmonella, representing 21.8% of all outbreaks. Overall, the outbreaks involved 6,616 cases, 1,719 hospitalisations and 3 deaths (in 3 different weakevidence outbreaks). In total, 18 MS reported 184 Salmonella outbreaks with strong-evidence (19.3% of all Salmonella FBOs). 20

28 TOP IMPROVEMENTS EFSA-ECDC 1.Descriptive data analyses human cases: domestic versus travel-related food-animal positive units: domestic versus imported 2.Data visualisation joint maps : human domestic cases domestic non-imported food-animal positive units 3. Salmonella serovar analyses priority: top-10 serovars as reported in humans also in foodanimals 28

29 FACELIFT : TRIGGERS (DRIVERS FOR CHANGE) The degree of harmonisation of the applied monitoring schemes and collected data limits the type of analysis that can be performed. Based on the obtained data, three main data categories can be distinguished: 29
