Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments Under the passive epidemiological surveillance system for poultry diseases, mortality was reported in heavy breeders on a multi-age farm; poultry showed clinical signs and lesions consistent with fowl typhoid (Salmonella Gallinarum). Routine bacteriological and relevant biochemical tests were performed, and Salmonella Gallinarum was diagnosed on 1st October 2020. The affected farm has been quarantined and farms in the area are subject to epidemiological surveillance with restrictions on bird movement and continuous surveillance by sampling. Disease presence has not been detected during investigations in the 10 km radius zone around the outbreak nor in farms epidemiologically linked to the affected farm; therefore, disease presence is restricted to the affected farm.
