Missouri 83190 Phans: (3)4) 884-1000 June 8, 1970 -OMMCCMMMi , P' -Ht-vO ->s Deer Sir: On February 9> 1970, we advised you by letter that several newspaper and magazine articles had been published Indicating that polyohlorlnated biphenyls (PCBs) have been discovered at eome points In some marine, aquatic and wildlife environments. Produots such as our Thermlnol PR series do contain ohlorlnated biphenyls. These products are: Thermlnol PR-Lo Temp Thermlnol PR-0 Thermlnol PR-1 Therminol PR-2 Thermlnol PR-3 In view of the faot that PCB has been found In the environment, there Is a possibility that the Pood and Drug Administration may plaoe a maximum limitation on the quantity of PCB in food. With these olroumstanoes in mind, we have reviewed the applications In whloh Thermlnol PR heat transfer fluids are used. The applica tion of Thermlnol PR fluids in food processing, such as to heat cooking oils for food preparation and to heat edible oils In deodorising processes, does appear to present a potential source for contaminating food products with PCBs. Because of the above faotore, we feel It Is In your interest as well as ours to use a different heat transfer fluid In your systems for those applications related to edible materials. Accordingly, we wish to inform you oonteminatlon exists. MUNS Oti9974 2We encourage you to change your heat tranefer fluid shortly and to contact your Monsanto representative for assistance.
