Go beyond food safety tests

The Ministry of Health's answer to our need for safeguards against recycled cooking oils still leaves us concerned.

The high-profile collaborative project to find ways to distinguish recycled cooking oils, which involves the ministry, six government departments and chemical scientists from across the country is yet to produce any credible results. All the five methods they have chosen so far have failed, we are told.

This is incredible. We have formidable technical capabilities that enable us to venture into space. But our scientists can't tell whether we are cooking with oils recycled from kitchen leftovers.
