A quarter of the 46 packed rice brands available in the market tested totally free of chemical residue, while the rest contained different levels - but only 2% was contaminated above the international standard, according to the Thai Foundation for Consumers.

The foundation's Chaladsue magazine on Tuesday revealed the results of tests jointly conducted with the Biothai Foundation on 46 bags of packed rice of different brands bought from hypermarkets and convenience stores. It reported that 12 of them contained no chemical residue - or 26.1% of the total sample.
