Presentation Transcript

Slide 1

Poultry Production in Maryland: Environmental Impacts and Community Health Issues Ellen Silbergeld EHS/BSPH July 2006

Slide 2

Research at JHSPH on Poultry Production EPIDEMIOLOGY EXPOSURE, HEALTH OUTCOMES PRODUCT MONITORING POULTRY PRODUCTS TESTING ENVIRONMENTAL STUDIES PATHWAYS AND ROUTES OF EXPOSURE AIR, WATER, DUSTS, SOILS BIOTIC TRANSFERS – WILDLIFE STUDIES MOLECULAR MICROBIOLOGY TRACKING PATHOGEN MOVEMENT TRACKING GENE TRANSFER MICROBIAL POPULATION GENETICS/DIVERSITY POLICY ANALYSIS ECONOMIC ANALYSES SCIENTIFIC BASIS for RISK ASSESSMENT

Slide 3

The CAFO (Concentrated Animal Feeding Operation): Changes in Food Animal Production since1930 Factory ranches – incorporated generation demonstrate Concentrated, high volume lodging and preparing Highly serious limitation Broad reconciliation of nourishment creation and circulation

Slide 4

THE GEOGRAPHIC CONCENTRATION OF POULTRY PRODUCTION – 50 YEARS in US poultry creation, 1949 Each spot = 50,000 chickens US poultry creation 1991 Each speck = 740,000 chickens

Slide 5

DELMARVA POULTRY INDUSTRY 600-800 million grill chickens delivered every year. 6000 oven chicken houses 2,500 chicken producers 15,000 poultry representatives Total yearly gross wage of Delmarva grill industry: surpasses 1.3 billion dollars.

Slide 7

Many Nonfood Routes of Exposure and Transfer ENVIRONMENT waterways and streams Irrigation Drinking water Bay Manure spreading Swimming Farm effluents Sewage Offal FARMS Slaughter Harvesting Processing Handling Preparation Consumption HUMANS Animal nourishes Farmers, specialists, groups High Risk Populations Children Elderly Immunocompromised Contact Adapted from Dr. Ruth Etzel USDA

Slide 8

THE OTHER PRODUCT OF CAFOs

Slide 9

The DelMarVa Penninsula: The "other item" of poultry creation >1,000,000 huge amounts of "compost" delivered by ~800 million chickens/yr Integrators claim the fowls Growers possess the waste Management - to a great extent arrive connected

Slide 10

Why are we concerned? More biosolids connected than land can deal with Contributes to surface and groundwater tainting Increased supplement spillover into surface waters Detectable nearness of medications and resistance determinants in groundwater

Slide 11

WHO IS AT RISK FOR EXPOSURE ? Laborers and producers who work in oven houses Workers who handle live chickens at preparing plants Household individuals from these people Community occupants

Slide 12

The Poultry Environment Health Study HYPOTHESES PERSONS WITH DIRECT EXPOSURE TO THE POULTRY ENVIRONMENT ARE AT INCREASED RISK OF EXPOSURE TO ABR EXPOSED PERSONS ARE AT INCREASED RISK OF BACTERIA-ASSOCIATED OUTCOMES THERE IS A GRADIENT OF EXPOSURE, AND HEALTH RISK, AMONG WORKERS, THEIR FAMILIES AND THE COMMUNITY

Slide 13

The Poultry Environment Health Study SUBJECTS POULTRY HOUSE WORKERS "LIVE HANGERS" GROWERS HOUSEHOLD MEMBERS COMMUNITY RESIDENTS

Slide 14

Working in the poultry business

Slide 15

Living close to the poultry business

Slide 16

The Poultry Environment Health Study EXPOSURE RISKS PATHOGENS ANTIBIOTIC RESISTANCE ANTIBIOTICS ARSENIC PATHWAYS AIR, WATER, DUSTS, WILDLIFE, CAUGHT FISH, FOOD PLANTS

Slide 17

AIRBORNE BACTERIA IN CAFOS ARE MULTI DRUG RESISTANT MDR ERYTH-R TET-R VM-R VAN-R Chapin et al (2005) EHP

Slide 18

Air discharges from CAFO ventilation frameworks

Slide 19

The Poultry Environment Health Study OUTCOMES BACTERIAL CARRIAGE REPORTED DIARRHEAL DISEASE RESPIRATORY FUNCTION TESTS NEUROLOGICAL SYMPTOMS METHODS ISOLATION OF BACTERIA FROM STOOL; MEASUREMENT OF ANTIBODIES IN SERA QUESTIONNAIRES RESPIRATORY FUNCTION TESTING

Slide 20

Poultry Health Study: Health Status in poultry workers– Preliminary Results Self announced indications: PW and referents PW report more incessant GI side effects OR 2-5 PW report a great deal more successive respiratory manifestations OR 2.6-35 PW report a great deal more regular neuromuscular side effects, including loss of motion, issues with vision and discourse OR 5.4-13.8

Slide 21

Arsenic sources - US

Slide 22

ARSENIC – THE FORGOTTEN ANTIBIOTIC broad utilization of arsenicals in grill nourishes recorded defilement of waste and revised land permeation into groundwater arsenic is a human cancer-causing agent and related with skin, liver, and cardiovascular sickness

Slide 23

ARSENIC and POULTRY Roxarsone, arsanilic corrosive utilized as a part of poultry as coccidiostats and development promoters – 45 g/ton sustain GP – ceaseless deep rooted presentation in bolsters arsenicals discharged (>70%) 100-200 mg/flying creature (900 million/yr) 50,000-90,000 mt/year arsenic arsenicals inorganic arsenic drain into groundwater

Slide 24

SHALLOW AQUIFERS IN DELMARVA

Slide 25

A SUGGESTIVE TRACE?

Slide 26

What does this educate us concerning avian influenza? ? ? ?

Slide 27

Wild avians contact poultry houses Photo graciousness of Dr Donald Burke

Slide 28

What are the dangers of word related contact and AF introduction? Three papers Koopmans et al (2004) National reconnaissance contemplate in Netherlands; side effect driven 2003 H7N7 flare-up HPAI All ranchers, specialists, families, veterinarians in episode locales Bridges et al (2001) Outbreak examination of poultry laborers and govt agents Hong Kong 1997-8 H5N1 Myers et al (2006) Cross sectional investigation of Iowa pork agriculturists, meat handling specialists, veterinarians; Univ of Iowa referent gathering Swine flu transmission dangers

Slide 29

Risks of Influenza A/(H5/N1) contamination in poultry specialists: Hong Kong 1997-8 Odds of immune response carriage: Farm/incubation center workers 2.7 Work on homestead >10% winged animal mortality 2.2 Touching live poultry 5.8 Feeding live poultry 2.4 Butchering live poultry 3.1 [referents: government workers] Occupational measurements: reaction watched
