H. S. Bergen -- H. L. fcinckler - H.Mir.'C P. S. Park - PPAPiC J. E. Springgate - JSPP.I :: 2 t s' < t * r TO W. B. Papageorge V7PAPA bTe have been in communication with a Dr. Hill of the Ohio Stata Board of Health. Ha has found PCD, particularly Aroclor 1254, in samples of milk from at least three herds in Ohio. He has traced this contamination back to silacc fgott three different silcs. Dr. Hill reported concentrations of 0.2 ppm of PC3 in the silage in the center of the silo and up to 20 pom in the raterial next to the walls. He also stated that concentrations in the milk were between 0.1 ppm and 0.6 pora and that some of the milk had been destroyed." The silos are concrete silos whose interior surfaces ware painted in 1967 using a formulation that contained 1254. I don't know if there was any other Aroclor in the formulatier nor do wc know the coating manufacturer; although, this comic be found out if important. The presence of PC3*in the silage came from flaking off cf the material and oossibly from leaching out during the silage storace. At orssent they will have to destroy about 150 tons of silage which ia valued at about 520 per ton. As a rough cuess, they consider there ::_ay be 50 other silos involved in Ohio that were painted with the same formulation. They are also looking into the fat con tamination of the ecus themselves. All in all, this could bo cruite a serious problem, having legal and publicity overtones. This brings us to a very serious point. Ehcn are we going to tell our customers not to use any Aroclcr in any paint formulation that contacts food, feed, or water for animals cr humans? Z think.it is very important that this be sens. It may be that sore of the customers will assure themselves cr. the basis of non-emtractability that a particular formulation might be safe but I think we should cake a blanket recom mendation against these uses. /y ?.
