CamCon: Control of Campylobacter in Broiler Chickens

CamCon is an EU FP7-funded project spanning four years from May 2011-May 2014. 

The UK, Denmark, Spain, Poland, Portugal, Norway and The Netherlands are all involved in various work packages, and the ultimate goal is to produce Campylobacter-free fresh chicken in Europe. 

Work at Liverpool is centred around identifying risk factors for Campylobacter colonisation of broiler flocks, with longitudinal sampling taking place both on-farm and at slaughter. 

The project is made up of:

8 farm longitudinal study (UK and Spain)

Which investigates on-farm risk factors such as:

  • ·         Numbers of people entering the house
  • ·         Other biosecurity measures (boot changing, use of foot dips, etc.)
  • ·         Environmental conditions inside the house, incl. litter pH and moisture content
  • ·         Environmental conditions/climate outside
  • ·         Vaccination and medication schedules

20 farm slaughter study (UK and Spain, Poland, Netherlands)

Comparing prevalence at slaughter with various risk factors, including:

  • ·         Flock size
  • ·         Flock health (pathologies recorded at slaughter)
  • ·         Farm biosecurity practices/management
  • ·         Geographical and climatic factors

Fly-screen intervention study (UK and Spain)

Testing whether preventing the entry of flies into broiler houses reduces Campylobacter colonisation of flocks.

The role of flies in transmission of Campylobacter (UK and Spain)

Investigating the prevalence of Campylobacter in flies captured on and around broiler farms.

Investigation of Campylobacter sub-types in European broilers

450 C. jejuni and C. coli isolates collected from broilers at slaughter from Spain (n=150), Poland (n=150) and Norway (n=150) are being typed using multi-locus sequence typing.  We hope to show the relationships between Campylobacter strains in chicken throughout the EU.
