(Yicai Global) Nov.1 -- Shares in China's leading pork processor WH Group and a subsidiary dived today after reports surfaced suggesting African swine fever had been found in one of its products in Taiwan.

WH Group stock [HKG:0288] fell 3.83 percent and shares in Henan Shuanghui Investment and Development [SHE:000895] closed 3.73 percent down.

WH Group is trying to verify a Taiwanese government statement that said African swine fever was found in a sausage made by the subsidiary and brought to the island by a tourist, the parent said in a statement today.

Pigs carrying the virus were found in a Shuanghui slaughterhouse in Henan province in August, the second outbreak of what is now an epidemic across the Chinese mainland. Some 30 of the 260 pigs transported to the slaughterhouse died from the disease, according to tests conducted by the China Animal Health and Epidemiology Center.
