1 Regional Seminar for OIE National Focal Points for Animal Production Food Safety Belgrade, Serbia, 15 th 17th October, 2013 Salmonellosis in poultry: country perspective preventing animal and human infections General Directorate of Agrarian Health Focal Point from Spain (MAGRAMA)

2 IMPORTANCE of SALMONELLA CONTROL PUBLIC HEALTH ANIMAL HEALTH ECONOMICAL Trade barriers: community trade &exports Marketing tool strategy Advantage for competitiviness or rule

5 Trend in reported confimed Salmonella human cases Spain

6 BASIC LEGISLATION ON ZOONOSES and SALMONELLA CONTROL Directive 2003/99/EC on the monitoring of zoonoses and zoonotic agents Regulation (EC) 2160/2003 on the control of Salmonella and other specificied food-borne zoonotic agents. Regulation (EC) 1177/2006 requirements for use of antimicrobials and vaccines in control programmes for poultry Regulation (EC) 2073/2005 microbiological criteria for foodstuffs Specific regulations for breeders, laying hens, broilers and turkeys

7 REGULATION (EC) 2160/2003 The purpose of this regulation is to ensure that proper and effective measures are taken to detect and to control Salmonella and other zoonotic bacteria at all relevant stages of the production chain, mainly at level of primary production, in order to reduce their prevalence and the risk they pose for public health.

8 Regulation (EC) 2160/2003 Zoonoses or zoonotic agent Animal sector Stage of food chain Target Control Programme compulsory from All serotypes of Salmonella with public health relevance: 5 serotipos (SE,ST,SH,SV,SI.) Breeding flocks of Gallus gallus (egg line and meat lines) Farms of breeding hens and rearing Máx 1% 1-january-2007 Serotypes of Salmonella with public health importance (SE,ST) Laying Hens Farms of laying hens Reduction % or máx 2% 1-january-2008 Serotypes of Salmonella with public health importance (SE,ST) Broilers Farms of broilers Máx 1% 1-january-2009 Serotypes of Salmonella with public health importance (SE,ST) Turkeys (breeders and fattening) Turkeys farms (breeding and fattening) Máx 1% 1-january-2010

9 NATIONAL MONITORING AND CONTROL PROGRAMMES OF SALMONELLA

10 Monitoring and control measures in NSCP FBO sampling (own-checks) and official sampling (official control) Use of antimicrobials (antibiotics not allowed) Vaccination Biosecurity measures Guides of Good Hygiene Practices

11 MEASURES IN CASE OF POSITIVE RESULTS Movement restriction for birds/products Sanitary slaugther Heat treatment of product Destruction birds/products Cleaning & Disinfection Restocking of new flocks

12 Prevention and control strategies Salmonella serotypes and prevalence may vary considerable between regions and countries and therefore, surveillance and identification of the most prevalent Salmonella serotypes in humans and poultry, and risk factors should be carried out in order to develop a more specific control programme for the area. Identification of critical points on we should apply more pression Better bacteria Control and erradication

13 LAYING HENS FARMS Risk factors: Cleaning & Disinfection Faeces from previous flock Dust Surfaces, frecuent elimination of faeces and cleaning of pits reduce environmental contamination Vectors & Pests (rodents control) S. Enteritidis most prevalent serotype Feed, and water?

14 BROILERS FARMS Risk factors: Cleaning & Disinfection: Litter and faeces from previous flock Dust Surfaces and tools feed and drinking devices Day-old-chickens (very important) Vehicles of transport to slaugtherhouse S. Enteritidis most prevalent serotype Bedding material, feed, water?

15 HOW TO REDUCE THE PREVALENCE AND CIRCULATION OF SALMONELLA? WORKING IN EACH PLACES WHERE SALMONELLA EXIST ENVIRONMENT BIRDS RODENTS INSECTS BIOSECURITY FEED

16 Control methods and tools Vaccination programmes Control of Biosecurity Good Hygiene Practices guidelines Feed and Water (specific control) Surveillance and monitoring of sampling programmes (Central Database for FBO & OC)

17 BACTERIA PREVENTION & CONTROL Vaccination programmes Live vaccines (S.E /S.T): Administration in drinking water: problems with water lines, tank capacity, products in water Killed vaccines (S.E / S.T): : Problems with doses, wrong injection site, operating speed too fast Complementary tool: Combined live-killed vaccination programmes offer best protection if risk is high

18 Hygiene and feed control Control of vehicles for transporting birds, feed,manure BIOSEGURITY Control drinking water x Pets control programmes x CONTROL POULTRY HEALTH CONTROL facilities and management Cleaning & Disinfectión RECORD- KEEPING Control of dead birds, litter, manure, sanitary wastes Visitors register and entrance

19 GUIDES TO GOOD HYGIENE PRACTICES

20 PESTS CONTROL Good Hygiene Practices Insect and rodent control

21 CONTROL OF FEED AND WATER Good Hygiene Practices Water Hygienic quality control Clorination Feed HCCPP practices Hygiene during transport and storage

22 IMPORTANCE OF CLEANING AND DISINFECTION 1. DRY CLEANING: SWEEP, BLOW AND VACCUM 2. WASHING WITH SOAP, DETERGENTS AND HOT WATER 3. DISINFECTION: Contact /Aerial 4. VERIFY C&D EFFECTIVENESS 5. NEW DISINFECTON IF NECESSARY

23 BACTERIA CONTROL Good Hygiene practices by FBO Training, good information and awarness of farmers Record keeping (feed, veterinary products,vaccines, sampling, visitors ) Hygienic barriers Importance of rodent control, proper C&D and vaccination

24 Training in sampling programmes Sampling by FBO // Official control by CA

25 Central Database of Official control: sampling and Biosecurity surveys

26 CENTRAL DATABASE FOR PRIVATE LABORATORIES (FBO control)

27 SOME CONCLUSIONS EU strategy based on harmonized monitoring, risk analysis and control programmes seems to be effective Importance of laboratory surveillance and supervision by Competent Authorities Vaccination, Biosecurity, C&D, pest control (rodents and insects) should be important parts of SCP Necessary collaboration and cooperation between CA and FBO a programme works only when everyone contribute to it.
