BEIJING — Canada has overtaken the United States as the top North American supplier of pork to China as farmers and meat packers in both nations battle for lucrative shares of the biggest global market.
Canada's pork sales to China, after a sharp rise last year, exceeded those of the US in the first quarter of 2017.
That's only happened a handful of times in two decades, according to US and Canadian government data.
Rising affluence is driving China's voracious appetite for pork, including parts of the pig－feet, elbows, innards－which command little value in most countries.
Nevertheless, it doesn't mean the productivity of farms in China has been reduced.
According to the data of the Food and Agriculture Organization, China, which is both the leading producer and the largest consumer of pork, rising pork consumption has led the sellers to take up the slack in supply by importing.
In fact, the imported pork products are not as popular as the imported beef in China. Some consumers have even never heard of imported pork.
"The fresh pork is local production, we don't have any imported pork supply," said Ito Yokado Beijing store official who is in charge of the store's fresh pork supply.
Beijing Central Key Trading Co Ltd, a Beijing-based food importer, said that the competitive price of imported pork was the major reason for it to do the business. The imported meat must be frozen during the transportation as a precondition, therefore the price is much lower than the fresh meat.
Drug-free exports
Canadian farmers have almost completely removed the growth drug ractopamine from their pigs' diet, largely because it is banned in China, which consumes half the world's pork.
In contrast, the US exports to China are limited because only about half of the nation's herd has been weaned off the drug, according to US hog producers, meat packers and animal feed dealers.
But major US-based firms are now moving to produce more ractopamine-free hogs－including the three biggest pork producers, Smithfield Foods, Seaboard Foods, a division of Seaboard Corp, and Triumph Foods, a hog farmer cooperative.
The rise of Canada's pork exports underscores the power of the gargantuan Chinese market to influence agricultural practices and profits in supplier countries worldwide.
As recently as 2013, annual US pork sales to China, some 333,000 metric tons, more than doubled Canada's shipments of 161,000 tons.
