What is wrong with that country? Excerpt:

Since late February, batches of cowpeas from the lush Sanya area of the island of Hainan have tested positive for a highly toxic pesticide, isocarbophos, that is banned from use on fruits and vegetables, according to a report on Tuesday in China Daily, the official English-language newspaper. Tainted cowpeas from here have been found in the provinces of Hubei, Guangdong, Anhui and Jiangsu.
The pesticide was banned in Hainan in 2004 but can still be found in remote parts of the island, China Daily reported. Some farmers still use it because it is much cheaper than legal pesticides.

Seriously, who can trust that any food exported from China is clean?
