Several National Taiwan University professors yesterday criticized the government’s efforts to crack down on food safety violations, saying that the snowballing recycled waste oil scandal highlights a lack of inter-ministerial cooperation and the ineffectiveness of the food safety management system.

Their remarks came one day after the Food and Drug Administration (FDA) released the results of laboratory tests that found the edible lard oil manufactured by Greater Kaohsiung-based Chang Guann Co (強冠企業), which included recycled waste oil collected from restaurant fryers, met legal standards.
