China has urged pork food firms to enhance their management of pork to guard against African swine fever after media reports of suspected contaminated dumplings.

Samples from three batches of pork-filled dumplings from Sanquan Foods tested positive for the nucleic acid associated with African swine fever, according to media reports.

The State Administration for Market Regulation and the Ministry of Agriculture and Rural Affairs urged the company to trace the source of the pork and dispose of related products.

The two ministries required local governments to beef up risk control measures, regulate information disclosure and crack down upon unscrupulous firms.

The African pig plague is a highly contagious viral disease that is believed to only infect pigs. No humans or other species have thus far been infected.
