The rest of the farms also stopped sending their products outside the border since they are near the affected areas. A farm in Hubei province also halted its production outside the border.

According to the report of the agriculture ministry, a new outbreak of the deadly virus occurred in Guangdong city of Huizhou which resulted in the death of 11 out of 90 pigs in a farm. The outbreak in Huizhou was followed by other cases of the outbreak. The outbreak in Guangdong is the third report of the spread of the virus within a week.

She said that about 3,500 to 4, 000 live pigs are supplied from the mainland to Hong Kong on a daily basis. There was also no sign of infection in the city since Tuesday night.

Chinese local officials are heightening their preventive measures. They banned farmers from feeding swill of animal origin to pigs. They also encouraged proper hygiene at farms.
