Chicago Mercantile Exchange (CME) hog futures sank to contract lows on Monday, with the market under pressure from plentiful supplies and weak demand for pork at grocery stores and on the export market, reported Reuters.

"The story remains one of a slow-to-move product market," brokerage StoneX said in a note to clients.

Cattle futures also were weaker as traders digested news from Friday about cattle disease.

The US Department of Agriculture (USDA) announced on Friday an atypical case of bovine spongiform encephalopathy (BSE), commonly called mad cow disease, in an older beef cow at a slaughter plant in South Carolina. USDA said the animal never entered slaughter channels and the agency did not expect any trade impacts as a result.
