Curb on reused cooking oil Date: Friday, February 07
Reuse of cooking oil sold as a second-hand product by huge food chains to street vendors is becoming a common phenomenon in Thai society, but health authorities plan to impose controls.
There are concerns that its use could lead to high incidents of cancer among the public, said Public Health Minister Sudarat Keyuraphan.
A ministry announcement to control the reuse of cooking oil is being drafted because currently there is no law to prevent its resale, she said.
Mrs Sudarat said the ministry has been working on possible controls on the use of used cooking oil for the past 4-5 months out of concern that it provided no health benefits. She said it has been reported that many big food manufacturers, particularly the fast food
chains, sell their used cooking oil to roadside vendors at a very low price.
``We need to outlaw this as we all know that most low-income earners like to consume fried food products from the roadside,'' said Mrs Sudarat.
Deputy public health permanent Secretary Pakdee Pothisiri said the National Food Commission, which met on Thursday, agreed on the urgency of introducing some controls to protect consumers.
He said something would have to be done quickly as current regulations only cover the sale of unused bottled oil products.
In addition, Mr Pakdee said the current law looks only at other aspects of the oil, and not at the presence of cancer-causing agents. It is feared that carcinogens, which cause cancer, could be present in used oil.
Mr Pakdee said a study on the widespread use of second-hand oil , which is being conducted by Kasetsart University, is expected to be concluded within the next two weeks.
