Thiruvananthapuram: Multiple ‘theories’ have emerged on the origins of African Swine outbreak in Wayanad.
An enquiry conducted by the animal husbandry department has revealed that even before the outbreak was officially confirmed in the district, 40 pigs of a farm died together in June. It is learnt that the farm owner approached Kerala Veterinary and Animal Sciences University for treatment for the remaining pigs but that also died. The samples were not sent for examination then. Another report is that the farm owner had slaughtered the remaining pigs when it was found to be infected. It is suspected that the virus had spread to other pigs. They were not buried as per protocol, said sources.
It is also suspected that other-state labourers might have acted as carriers of virus. The outbreaks were reported in other parts of India and the virus might have reached here through their cloths or footwear. Assam, Bihar and Nagaland had reported swine fever outbreak.
Farm owners said that the entry of pigs from other states was restricted only from July 14 and by that time virus spread had occured here.
