Major Chinese animal feed maker Tangrenshen Group reported Sunday that feed produced by one of its units had been contaminated with African swine fever.
As the US pig industry looks to further refine its biosecurity procedures, the US feed industry faces questions related to its supply chain and manufacturing processes and procedures.
One of China’s top animal feed producers on Tuesday said an affiliated firm had culled nearly 20,000 pigs due to a suspected case of African swine fever.
Based on current research, a holding time of 78 days after the date of manufacturing and bagging or sealing to prevent additional contamination for amino acids, minerals or vitamins will degrade 99.99 percent of viral contamination.
Food production is increasingly competitive and with that comes rising pressure around feed safety but big data, strong validation of controls and knowing your supply chain from farm to fork can help, said experts at Kemin's feed safety conference in Antwerp, Belgium last week.
While feed and ingredients are not the most likely sources of introduction and transmission of African Swine Fever Virus (ASFV) and Classical Swine Fever Virus (CSFV), they are a documented vector for disease.
Ongoing swine health research seeks to track the potential for virus-infected feed to cause the related disease in pigs.
Outbreaks of African Swine Fever in China are raising concerns for swine producers in the US as the disease may be able to survive the importing process in feed or feed ingredients, says expert.
Recent research suggests more emphasis on feed biosecurity, particularly in imported ingredients, could help reduce the risk of introducing foreign animal diseases into US livestock herds.
Meeting sets priorities for research and investigation into feed transmission risk and mitigation.
