 The gloves used during cooking or packaging were sprayed with 00% ( w/w ) ethanol to sterilize them . PVC gloves from the factory contained 00 or 00% by weight of DEHP . To confirm the link with the contamination problem , samples of boiled rice , croquette and boiled dry radish were handled in the laboratory with PVC gloves containing 00% ( w/w ) DEHP . DEHP migration levels of 0 . 00 mg/kg in rice or 0 . 00 mg/kg in croquette , and 00 . 0 mg/kg in radish were found . The alcohol sprayed onto the gloves increased the migration of DEHP to 0 . 00 mg/kg in rice , 0 . 00 mg , kg in croquette , and 00 . 0 mg/kg in radish .
