Shao Mingli, commissioner of the State Food and Drug Administration (SFDA), said more food and drug scares may appear in the future as suppliers try to cut costs in a failing economy, the South China Morning Post reported, citing state media. The warning comes during an investigation into tainted dog food that has reportedly caused the death of 30 dogs from liver complications. The dog food was tainted with aflatoxin, but the General Administration of Quality Supervision, Inspection and Quarantine said it had never approved the dog food for import, nor had the food gone through quarantine at the border. China faced a tainted milk scandal in 2008 that killed six children and sickened thousands. The SFDA also said that it dealt with nearly 3,000 cases of illegal drugs and medical equipment in 2008.
