Another blow for Thai rice

US researcher finds elevated lead risk

- +

The Thai rice industry, already reeling from a staggering stockpile thanks to the government's rice pledging programme, took a body blow courtesy of an analysis of commercially available rice imported to the US that was found to contain levels of lead far higher than regulations suggest are safe. 

The report at the annual meeting of the American Chemical Society was by a group of researchers led by Tsanangurayi Tongesayi, an associate professor of chemistry at Monmouth University in New Jersey, and noted the imports, which make up 7% of the rice consumed in the US, contained higher than acceptable levels of lead.

The levels ranged from 6 milligrammes per kilogramme to 12 mg/kg, factoring in average consumption, meaning estimated lead exposure levels of 30 to 60 times greater than the Food and Drug Administration's provisional total tolerable intake (PTTI) levels for children, and 20-40 times greater than the standard exposure levels for adults.
