Hong Kong (CNN Business) African swine fever has wiped out a third of China's pig population. Now government officials are discussing dramatic steps to stabilize the world's largest pork market.

Pork is a huge deal in China. The country is home to half of all the pigs on the planet. The meat is a staple of the Chinese diet, which means its scarcity could damage China's social stability . The outbreak of swine fever also threatens to upend the global pork supply chain.

While Chinese authorities have already made plans to shore up the pig market — including subsidies for pig farms and families who may struggle with soaring prices — they're stepping up efforts to deal with the crisis.

The price retailers pay for pork has spiked nearly 70% in the last year. And the average price that wholesalers pay suppliers was up 90% in the last week of August compared to a year ago, according to government data. Analysts say prices could yet go even higher.
