March 23 1972 Mr. Franklin P. Perdue Proaidant Perduo Incorporated P. 0. Box 1537 Salisbury, Maryland 21801 Dear Mr. Perdue< I understand end appreciate the concern you expressed In your letter dated March 21, relating to the PCB problem and Its effect on the poultry Industry. To the best of our knowledge and belief we have not, since the summer of 1971, sold PCB-containing materials to anyone in the production of ingredients used in poultry feeds. I am personally completely frustrated in attempting to determine the source of high levels of PCB's Involved in the Maine inddant. With Monsanto's ban on the sale of PCB's to the food related industry an incident such as the one in North Carolina should not reoccur. ' Since December, Monsanto instituted a program to further reduce the use of PCB's. Our current objective is to remove it from all uses except as a dielectric fluid in the electrical industry. No alternative material Is known to exist today and the benefits related to the safety features of fira and explosion resistance are believed to far outweigh the threat of environmental con tamination from these closed system applications. Your proposal to insist on certificates of analysis with an upper limit of 0.5 parts par million PCB's appears to have merit and is followed in other Industries. The FDA has pro- posod regulations relating to the amount of PCB that will be tolerated in animal food Ingredients find in animal feed. Z MONS 091624 Hr. Franklin P. Perdue Perdue Incorporated 2 March 23, 1972 havo attached a copy for your uea. You may wish to review the 0.5 ppm limit in light of tha 5 ppm limit the FDA ia proponing for each ingredient. Z hope thie information is useful to you. If X can be of further service, please let me know. Sincerely, VSP/er Attachment W. B. Papagoorgo Manager Environmental Protection MONS 091625
