Epidemiological assessment of Mycobacterium avium subsp. paratuberculosis (MAP) in target herds

Project Reference: 03-RESR-001

Status: Completed

Commencement Date: May, 2003

Project Duration: 18 months


This research was commissioned in order to carry out follow-up veterinary investigation of suspect Mycobacterium avium subsp. paratuberculosis (MAP)-positive herds identified in an earlier safefood project.

The objectives of this research were:

  1. to validate the use of milk filters as a cost-effective, reliable methodology for screening dairy herds for the presence of MAP
  2. to identify critical risk factors for spread of MAP infection between and within herds on milk production holdings by testing milk filters, bulk tank milk, bloods from individual animals, water sources and rabbit faeces
  3. to recommend practical control measures to the farmers concerned in relation to herd health, herd management, hygiene practices and environmental standards.
