This information is prepared for internal use only and should be used with discretion, since it has not been completely evaluated for such considerations as toxicity and patent conflict, except as specifically stated. Sales Information Bulletin No. 57 SUBJECT: PDA PRESS CONFERENCE ON PCBs DATE: OCTOBER 13, 1971 . Attached is a copy of Pood .Chemical News (October 4, 1971 issue) which covers the recent PDA Press Conference on PCBs. At pre sent the PDA opposes a ban on sales of PCBs but this should not lead to complacency on the part of any user of PCBs. Government agencies may not maintain this attitude if there is evidence of PCBs still being used in areas where food supplies (in the widest sense) can be contaminated either directly or indirectly. This means we must continue our efforts on heat transfer fluid con versions in "peripheral" applications. We must make sure that pollution control is being practiced in plants where PCBs can still be used (e.g. dielectrics). We must encourage PCB users to return waste fluid to W.G.K. for Incineration. Your cooperation is_ appreciated and if the Product Group or management in St. Louis can help you further in customer con tacts, please let me know. We will give field sales all the help we can. cs Attachment Cumming Paton DSW 183162 NOTICE: "Nothing contained herein is to be construed as a recommendation to use any product in conflict with any patent.

Monsanto told FDA in a Sept. 8 meeting, it was disclosed, that PCB sales would be llrtiited to "essential closed system uses with no use in food or feed plants." In a Sept. 3 meeting between FDA and the American Paper Institute, FDA was told . that National Cash Register had discontinued PCB use in copy paper. It was also disclosed during questioning that manufacturers' trim from the so-called "carbonless copy paper" that had been routinely used in recycled paper until recently'is no longer being used for packaging. Representatives of paper manufactuiers said at the pi ess conference that any sucii copy paper picked up here after in recycling programs would not tend to be put into food-grade paper. It was disclosed outside of the press conference last week that FDA is seeking eight injunctions against shippers ana smokers of chubs from the Great Lakes. Of 53 Lake Michigan samples, FDA.found S with more than 5 p.p.m. PCB and 37 with over 5 p.p.m. DDT. Both FDA and Agriculture Department officials said that the cause of contamination' in 50,000 turkeys in Minnesota has not yet been established (See FOOD CHEMICAL ' NEWS, Sept. 27, Page 30). However, Clayton Yeutter, Administrator of USDA's Consumer and Marketing Service , said CMS is reducing its testing in Minnesota and the Dakotas because the con tamination was "an isolated occurrence." In a press release, USDA said: "All the turkeys were produced, under grower contracts, by a single company and consumed feed produced by the company's mill in V/adena, Minn. The mill's output of feed is used only for the one company's turkeys. ' "CMS officials said results of tests by a private laboratory -- and confirmed by CMS laboratories - - on live turkeys c c at eight farms that contract with the company show that no birds exceed the FDA administrative guidelines. DSW 183163 STLCOPCB4051064 Page 4 October Aj 1971 rOOD CHEMICAL NEWS "Samples from turkeys produced by other growers In Minnesota, North Dakota and South Dakota also were within acceptable levels." . <' . FDA's Edwards bluntly resisted a recently renewed call by Rep. Ryan (D-N.Y.) for legislation banning all uses of PCBs. Edwards said: "We reject the need and in fact the feasibility as some ' have proposed for an outright ban on the substances. Although the use of PCBs requires control, an outright ban is not- feasible and would not be in the best interest of the consumer." . The reason for the hastily-called press conference was noted in Edwards' reference to "crisis headlines and demands for national health alerts." Washington papers have been running the series of PCB incidents on front and editorial pages, and Ralph Nader's associates have continued to question FDA's handling of the incidents. In a Sept. 20 letter to Edwards, Nader renewed several earlier charges (See FOOD CHEMICAL NEWS, August 23., Page 20), and Nader said Edwards was posing false issues in referring to "emotionalism,, scare headlines, and good science." . Nader said: .. "FDA does not serve the cause of rationality and public confidence when it conceals the facts from a public which . . . wants more information about the product he buys and whose questions cannot be ignored. ` "The 'good science' that you invoke does not challenge the existence of long-term hazards from persistent low- * level accumulations of such substances, nor does science, good or bad, have anything to say about the obligation of FDA to tell the public the full truth in timely fashion. Moreover, your own scientists are far from united con cerning the accuracy or responsibility of FDA's public statements during this crisis." * ' Giving the press conference the air of a "command performance," Edwards was accompanied by Deputy Commissioner James Grant; Reo Duggan, FDA Deputy Associate Commissioner for Compliance; Bureau .of Foods Director Virgil Wodicka and Deputy Director Albert Kolbye, Jr. The latter set forth current information on PCB toxicity. '. Kolbye prefaced his remarks with the statement, "... All available evidence indicates that PCBs (in terms of acute toxicity)' are classifiable as being of moderate toxicity." He noted that PCBs are less toxic than DDT, which is one of the safest pesticides in acute toxicity terms. He reviewed toxicity findings from a Japanese incident and rat and mice studies which showed alterations of liver metabolism and other damage. He said: '' " DSW183164 Q` S t-. tr oo STLCOPCB4051065 j October 4, 19 71 Page 5 FOOD CHEMICAL NEWS . . "Animal and human data both point to 150 to 300 micrograms per day as being in the range of safety as far as a temporary dietary intake over the relatively short period of time that we as a society will be forced to tolerate the presence of these chemicals in our food supply. .. . "Since 2,000 milligrams was reported to be the total dose . - causing an effect in the Japanese, then 200 milligram total dosage PCBs can probably bo tolerated over a protracted . period of time without significant adverse effect. "It would take 22 months of daily Ingestion of 300 micrograms of PCBs to arrive at a total ingestion of 200 milligrams ..." He also said FDA is not aware of any foods contaminated at significant levels on a regular and consistent basis. ' Kolbye spoke the day after the press conference to a Governors' Five-State Inter disciplinary Pesticide Council meeting in Chicago, elaborating toxicity data and stating: "To summarize what is presently known, the no-effect level in test mammals may approximate 10 p.p.m. in the diet. Based on this animal data, with allowance for a 1,500 gm human dietary food intake, the Acceptable Daily Intake would permit a 100-fold margin' of safety if set at 150 micrograms PCBs per day." - * . * . . . Hinting at the possibility of future guideline action, he said that until long-range feeding studies being conducted by Monsanto have been completed, FDA is unwilling to establish formal guideline levels for PCBs in food. During the press conference, FDA's Duggan reported on FDA market basket testing for PCBs and testing of packaging materials. Of 720 composite samples during fiscal years 1970 and 1971, 22 were found to contain PCB residues ranging from a trace to 0.36 p.p.m. In three cases, the source of the PCBs were packaging materials. No PCBs have been found in fresh fruits or vegetables, he noted. Tabulations appended to Duggan's statement showed separate breakdowns for paekaaina and for foods. DSW 183165 The following levels of PCBs were found in various types of packaging: Gardner board, 73 p.p.m.; Sulfate board, 1,7 to 4.7; Paperboard food packaging, 29 to 433; Chip board, 46; cartons for shredded wheat, 14 to 18; cookie boxes,'33; cracker boxes, i 9 to 132; spaghetti and noodle cartons, 12 to 2l; powdered sugar, 17; cartons for white hominy grits, 16 to 39; cereals, 29 to 47; and corn meal and mixes, 6.7 to 12. However, fewer foods were found to be contaminated. The list included: : Shredded w-hoat in cardboard cartons, none to 0.5 p.p.m.; spaghetti and noodle dinners, 0.3 lo 3,0; quick grits, 0.4 to 0.6; cereals, 0.8 to 1.9; shredded wheat, 24; corn meal and mixe STLCOPCB4051066 Page 6 October 4, 1971 Oct FOOD CHEMICAL NEWS However, the same day as FDA's press conference, Ryan renewed hts call for legislation and characterized PCBs as "extremely pervasive, persistent poisons which accumulate in body tissues and, at threshold concentrations at present unknown, constitute a severe threat to health." He charged: "FDA officials have repeatedly attempted to lull the public into a false sense of security." Cabling continued reliance on industry self-control inadequate, Ryan said there are no true closed systems. He demanded: . "The only thing that will insure that future contamination from PCBs does not occur is to eliminate them totally -- as proposed in my legislation, HR 10085. "What is needed is preventive action by the responsible federal agencies and full and timely disclosure of any and all food adulteration and contamination to the American public." ........................ . . . ALTERNATIVES TO FAT SOURCE LABELING SUGGESTED ' The Frozen Potato Products Institute last week suggested to the.Food and Drug Administration five possible alternatives to the agency's proposal for fat and oil source label declarations in descending order of predominance (See FOOD CHEM ICAL NEWS, Sept. 27, Page 19). Most of the comments filed recently with FDA have attacked the source labeling proposal. FPPI also hit use of the label terms "hydrogenated," "partially hydro genated," and "hardened." . As its first-choice alternative, the Institute suggested that the source labeling should "only be required if a representation is made that the product is for special dietary or nutritional use by man." Its second-choice suggestion was that manu facturers should have the option of listing specific oils and fat if they choose. As a third* alternative, FPPI.said a product label could "only be required to say whether or not it contains any animal fat at all." As a fourth choice, the letter said ingredients could be listed "by groupings and not by specific content in a particular package (e.g., 'May contain various blends of one or more of beef, corn, cottonseed, soybean, or palm oil')." The group's fifth choice would entail the required listing of any animal, fats or oils. Chicago Shortening asked whether there is "something wrong with-the word 'Shorten ing,'" saying if there is anything injurious about it the public should be educated about it. If not, the firm said, there is no reason to change use of the word "shortening." DSW183166 E Enforcement of source labeling would be "impossible," Chicago Shortening said, . adding, "This is like prohibition; it will lead to an undesirable element who realize that it is impossible to definitely establish what is hydrogenated and what is not." STLCOPCB4051067 'age 26 * )ctcer A,' 1971 .* FOOD CHEMICAL NEWS "To the extent practicable, such research shall utilize data on human exposure which relates to consumption patterns and the accumulative effect on human metabolism." . The staff revision also extends from 90 to 180 days the period in which the Food aM Drug Administration is required to propose regulations specifying the dangerous materials and the Intensive screening procedures that will be followed,to eliminate them from the food supply. The new section carries an appeal procedure, for persons adversely affected by these FDA decisions. New safeguards are also written into the bill to allow firms to seek injunctions against FDA in cases in which the agency attempts to lift a certificate, which is a requirement for operation. A firm may also sue for an Injunction of decisions by FDA to withhold approval'of labeling or packaging of fish or fishery products, which must be submitted to FDA for pre-clearance under procedures similar to the Department of Agriculture control of meat and poultry labeling and packaging. In another change, the bill now makes the use of an "official mark" discretionary. Originally, the bill required the mark or" the official inspection legend on all fish packages. The National Canners Association, in comments submitted informally on a previous draft, pointed out that the legend or mark is unnecessary because all fishery products become subject to approved inspection programs (See FOOD CHEMICAL NEWS, July 19, Page 30). In another change, the bill permits fish or fishery products that are in a perishable form to be processed to the extent necessary to prevent spoilage, in cases where FDA segregates products it believes may be adulterated. After segregation for 10 days, the product may be condemned, unless an objection is made. The firm is then provided with a hearing and an opportunity for judicial review. Under the new Hart bill, "continuous inspection" is defined as inspection "by an inspector at least once daily or at such less frequent intervals as may be t ! prescribed . . . where daily inspection cannot reasonably be provided because of the Illness, weather, or other extreme conditions beyond the control of the inspector." . As a part of such inspection, the bill says, an inspector may be required to be ' "on duty at all times during which the processor is operating or that the processor himself be instructed to monitor the operations or the fish and fishery products of the establishment in the absence of the inspector." . O. RECALLS: TROUT, CATFISH CHOWS; FISHMEAL, MEATMEAL - ^ The Ralston Purina Co., St. Louis, Mo. , was voluntarily recalling nationwide from users seven varieties of Purina Trout Chow and four varieties of Catfish Chow produced at its Richmond, Ind, , and Memphis, Tenn., plants because of contamination with polychlorinated biphenyls. .
