BEIJING (Reuters) – China’s agriculture ministry on Tuesday said two new cases of African swine fever had been confirmed in the central province of Hunan.

The confirmation of the cases, in the cities of Yiyang and Changde, could stoke worries over pork supplies a day after two other fresh cases were reported in the southwestern province of Yunnan.

The ministry said 546 hogs in a pig farm in Yiyang and 268 hogs in Changde were culled after infections were found.
