Clark Manufacturing Chemists Assn. 1825 Connecticut Avenue, N.V. Washington, DC 20009 Dear Mr. Clark: This is to acknowledge receipt of your letter of March 23, 1976, transmitting tho final report entitled, "The Effects of Maternally Inhaled Vinyl Chloride on Embroyonal and Fetal Development in Mice, Rats and Rabbits." This information vill be considered in our evaluation of the use of vinyl chloride polymers in contact with food. Accordingly, as you are aware. It may be necessary to place this report on public display at the Hearing Clerk vhen final regulations are published. We have not been conducting any animal studies on the potential toxicity of FD&C Red Wo. 2. We have been analyzing various samples of PVC coatings, gasket material, plasticized film, and flexible tubing. To date, we have been unable to detect any migration of vinyl chloride from these types of articles at a leva1 of sensitivity of 1 part per billion. We are looking forward to the receipt of further reports of the studies being sponsored by MCA. Sineerely yours, J&i*// 9n Gerad L.
