2010 EU Summary Report on Zoonoses: overview on Campylobacter

Transcription

1 Committed since 2002 to ensuring that Europe s food is safe 2010 EU Summary Report on Zoonoses: overview on Campylobacter Giusi Amore Unit on Biological Monitoring, EFSA EURL - Campylobacter workshop, Uppsala, 1-3 October 2012

2 Outline EFSA EFSA s BIOMO unit Zoonoses data collection 2010 EU Summary Report on Zoonoses Main findings on Campylobacter Conclusions

3 European Food Safety Authority EFSA s tasks 1. Provide independent scientific advice and support for EU legislation and policies in all fields that impact food and feed safety 2. Collect and analyse data to allow characterisation and monitoring of risks 3. Promote and coordinate development of uniform risk assessment methodologies 4. Communicate risks related to all aspects of EFSA s mandate

4 EFSA s organisational structure

5 Biological Monitoring Unit (BIOMO) Activities currently focused on three areas: Annual data collection and reporting on zoonoses, AMR and food-borne outbreaks in EU Survey design and analyses of EU-wide baseline surveys on zoonotic agents in animals and food Meat inspection mandate define epidemiological criteria for adaptations of current meat inspection methodology

6 EUSR: zoonoses data collection Directive on the monitoring of zoonoses and zoonotic agents (2003/99/EC) gives EFSA the task to examine the data collected from the Member States and to publish an annual EU summary report (EUSR) EFSA took over the task in 2005 MSs have an obligation to report each year

7 EUSR: zoonoses data collection Data collection mandatory for 8 zoonoses: Salmonella (+ antimicrobial resistance) Campylobacter (+ antimicrobial resistance) Listeria monocytogenes Brucella Tuberculosis due to Mycobacterium bovis Verotoxigenic Escherichia coli Trichinella Echinococcus And also for foodborne outbreaks

8 EUSR: zoonoses data collection For other zoonoses the monitoring is requested according to the epidemiological situation in each MS: Viral zoonoses Bacterial zoonoses Parasitic zoonoses Currently 7 additional zoonoses covered Additionally 3 microbiological contaminants

9 EUSR: analyses of the annual monitoring data Analyses of trends over the years (in MS/ EU) Identification of sources of human infections (which foodstuffs / animal species) Comparison of prevalence/proportion positives at different food/animal categories/points of food chain Analyses of food-borne outbreak data Spatial (geographical) distributions (maps)

10 EUSR: reporting scheme in EU

11 EUSR: zoonoses data collection The EFSA web application and manuals provide the format of the reporting (standardised tables, categorisations of food and animals, definitions)

12 EUSR 2010 EFSA collects and analyse data on zoonoses and publishes an annual EU Summary Report in collaboration with the European Centre for Disease Prevention and Control (ECDC) ECDC provides for and analyses the data on human zoonoses cases 12

13 Human zoonoses cases & notification rates, EU, 2010

14 Confirmed cases per 100,000 population Human Campylobacter cases in EU, Significant increasing trend in the EU notification rate of confirmed cases in the last five years ( ), more evident since 2008 In 2010, the number of notified cases of thermotolerant Campylobacter in the EU increased by 6.7 % compared with Year

15 EUSR Zoonoses 2010: Campylobacter in humans Number of reported confirmed campylobacteriosis cases in humans by month, TESSy data for reporting Member States, 2010

16 Campylobacter in food in EU,

17 Campylobacter in food, 2010 Number of samples within food categories tested ranged from a few to several thousand samples. Majority of the samples were from food of animal origin primarily from poultry meat. Sampling and testing methods varied between countries results from different countries are not directly comparable. Proportion of positive samples may be influenced by the time of year at which samples were taken. in many countries Campylobacter are known to be more prevalent during summer than during winter.

18 Proportion of positive samples Campylobacter in food in EU, 2010 Campylobacter is most frequently reported in fresh broiler meat among foodstuffs as in previous years. The overall proportion of Campylobacter-positive broiler meat samples has remained at a stable high level in the reporting MSs group since Year

19 Species distribution of Campylobacter isolates from fresh broiler meat, 2010 Source: Includes data from 16 MSs Note: Some of the isolates might be positive with more than one species. N=2,386. Data where sample size is <25 are also included. As in 2009, C. jejuni accounted for approximately one third of the isolates Almost half of the Campylobacter isolates was reported only as Campylobacter spp. 5 MSs reported C. coli as predominant species in fresh broiler meat (AT, HU, IE, PL, RO) C. jejuni was reported as predominant species in 3 MS (DE, LU, SI).

20 Campylobacter in animals in EU, 2010 Animal category Number MSs reporting N % positives Broilers Broiler flocks 8 9, Pigs Pig herds Cattle 7 3, Cattle herds

21 Species distribution of positive samples isolated from broilers, cattle and pigs, 2008 Data from 16 MSs + 2 non-ms, N=14,192 Data from 12 MSs + 2 non-ms, N=10,028 Note: Some of the isolates might be positive with more than one species. Data from 9 MSs + 1 non-ms, N=1,709

22 Overview of Campylobacter data reported by MSs in 2010 from broilers, pigs, bovine animals and food thereof The proportion of positive samples is much higher in pig and cattle populations than in samples of fresh pig and bovine meat at processing and retail. Among broilers, the prevalence of Campylobacter does not decrease notably from live animals along the food chain to retail Note: Data are only presented for sample size 25. Each point represents a MS observation

23 Conclusions Campylobacteriosis has, since 2005, continued to be the most commonly reported zoonosis in humans in the EU. Significant increasing trend in the EU notification rate of confirmed cases in the last five years Poultry meat still appears to be the most important food-borne source of Campylobacter since the occurrence of the bacteria remained at a high level in fresh poultry meat. The importance of poultry meat and milk as sources of human Campylobacter infections was supported by the reported food-borne outbreak (FBO) data from 2010: two-third (17 out of 27) of the Campylobacter strong evidence FBOs were linked to broiler meat. Five of the outbreaks where attributed to raw milk. 23
