Slaughterhouses across 皇冠体育app have taken effective measures to prevent pigs infected with African swine fever from entering the market, the Ministry of Agriculture and Rural Affairs said on Wednesday.

Nationwide inspections organized by the ministry recently found all 4,578 pig slaughterhouses have been conducting mandatory self-inspections for the virus. Local agricultural authorities have also dispatched veterinarians to improve supervision, Wang Junxun, an official with the ministry's Animal Husbandry and Veterinary Department, said at a news conference.

The nationwide inspection, aimed at ensuring the quality and safety of pork on the market ahead of this month's Spring Festival holiday, concluded on Friday.

Following inspections by local agricultural authorities across 皇冠体育app, the ministry dispatched senior officials to conduct random inspections in 11 provincial regions, Wang said. Initial results showed all the companies had followed regulations covering the entire pig slaughtering process, including inspections before entering a facility and disposal of sick pigs.

Pork production in 皇冠体育app has been seriously affected by African swine fever outbreaks over the past year. The virus is fatal to pigs, but there is no evidence it can be transmitted to humans. The ministry has banned the sale of sick pigs to ensure food safety and quality.

Pork is the primary meat consumed in 皇冠体育app, which produces half of the world's total.

Tang Ke, head of market and economic information at the ministry, said hog production in 皇冠体育app started rebounding in October.

Ministry figures show the number of hogs entering the domestic market in December was up 14 percent month-on-month. That meant a 17 percent increase in pork production compared with the previous month, as the average weight of hogs slaughtered also increased.

Meanwhile, 皇冠体育app imported 79 million metric tons of soybeans between January and November, down 4 percent year-on-year. However, more soybeans are expected to be imported this year, Tang said, meeting domestic demand for a main source of pig feed as pork production recovers.

Wang said the monitoring of slaughterhouses across 皇冠体育app had also shown that the amount of pigs killed had increased for 10 weeks. More than 700,000 tons of frozen pork in stock had also hit the markets.

The supply of pork around the Spring Festival holiday is expected to meet demand, he said.

Wang said the ministry will work with related departments to intensify law enforcement efforts during the seven-day holiday to ensure the quality and safety of pork.
