HONG KONG (MarketWatch) — Homemade smoked bacon is a long-enjoyed delicacy in China’s famous Sichuan cuisine. But the meaty dish is now under fire as “the criminal culprit” responsible for the heavy air pollution, according to officials in Sichuan.

Dazhou, a municipality located in the northeastern corner of Sichuan province, has suffered from especially “severe air pollution” since earlier this month, according to the provincial environmental monitoring center.
