  3. IMPORTANCE • in industrialised countries by food or drinks (water, milk etc) • as occupational diseases rare • in animal contact • in environments where animals are Markku Seuri, FIOH, 2004

  4. IN EU • Council Directive 92/117/EEC: • yearly report on the zoonoses situation in the country • the following is based on the Finnish zoonoses report in 1995 - 1999 Markku Seuri, FIOH, 2004

  6. BRUCELLOSIS • brucellosis free status of bovine herds • latest case in cattle in 1960 • brucellosis free status of ovine (sheep) and caprine (coat) herds • never recorded in Finland • porcine brucellosis has been recorded in Finland • 0-2 human cases a year; mostly from food eaten abroad Markku Seuri, FIOH, 2004

  7. SALMONELLA • in 2002 found in two broiler breeding flocks and in one turkey breeding flock • no cases in egg production • in 9 herds of cattle • none in swine • in man 500 - 1 300 domestic cases yearly; 2500 - 3500 abroad • no occupational cases known Markku Seuri, FIOH, 2004

  10. LISTEROSIS • listed as a zoonotic disease even if it is mostly a microbe of the soil • for animals Listeria rarely causes diseases • importance in food-chain: • it can grow in temperatures found in refrigerators • commonly found in soil and animal faeces • commonly by food, very rarely by direct contact to sick animal Markku Seuri, FIOH, 2004

  11. YERSINOSIS • the third most common cause of bacterial gastrointestinal infections (after Campylobacter and Salmonella) • 2002 695 cases reported • by food or drinks • according to the serologic studies occupational exposure is evident, but clinical disease? • Occupational nature no shown Markku Seuri, FIOH, 2004
