Gentlemen* - I enclose oopy of a letter from Dr. Cowgill, dated February 24th, in -which he gives me the specifications of the government -with reference to various articles deleterious to food. In order to be thoroughly protected at the end of this investigation, I would suggest that you authorise the examination of the latex which has been sent up to see if any of these other substances are present in any appreciable amounts. Very truly yours. CHICLE DEVELOPMENT COMPANY ssY- w Enel. cot ORC resident 0006440 February 24th 1950 Hr.S.S. Tates President C h i d e Development Company 600 Fifth Avenue New York City# Dear Mr. Tates, In answer to your letter of February 11th as] ig about present government tolerances I submit the following data* piSome years ago the TJ.S. governmental authorities it copper and zino should not be present in amounts greater than 50 and 1C ermillion, respectively Upon consulting Dr. Bailey of te"'t?^eotiout Agricultural Experiment Station I learn that to the best of his 3mowledge~the^*e has neveHJjeen any aotion taken with respect to these particular metdls* The other tolerances that have been definitely stated and which have served as the basis for regulatory actions, refer to araefaio, ^fiurorine and lead * the exact tolerances for these elements are 1#4, T#saSi'^7ETMp7p#m respectively From time to time in the past these hj3ve~ben subjeoted to slight ohanges as improvements in the methods of spraying fruit^tiees^h^^ beeh^d^veloped. The figures just given are the present toleranoes* The researoh division of the; food and Drug Administration is studying in this con nection some other elements wiiich are presen-c in foods in relatively minute amounts Perhaps the most interesting yr^k along this line at the present time concerns the element selenium_jhloh ooc srsoiable amounts in oertain soils of the . . - kmiddle and far-wefitern~8th!tes, 'has been found to be extracted and eon- centrated in oerti&n plants, notably the wheat plant, with the result that the plant is rendered toxie and thi refore unfit to use as a food* It would not be sur- prising if, afjfc^r more rese ' has been done, some regulations and a toleranoe for selenium should be established When in Washington, January 2nd, Dr. Skinner, Direotor of the Research Division of the Food and Drug Administration, told me oonfidentially \tha in addition to selenium, some other element, at present unidenti fied, is responsible^TOr jcertain phenomena of toxioity now being studied in the western states by the federal government) one guess that was serving as a basis for further researoh was that this element might be molybdenum. From the standpoint of your particular problem I think it would be suffioient to make a few ohemioal analyses of representative products of interest for the different metals mentioned above, but most particularly for arsenic and fluorine, because these two are at present very muoh. at the feous of attention of the government officials K 0006441 I do not know to what extent you are interested in the regulations of foreign countries For the manufacturers of certain products that are exported in large quantities* suoh foreign regulations m y he of particular interest* As an illustration one mayjoite the fact that Austrian regulations specify more ihan 100 parts per million of tin as injurious to healths in this particular oase, however, there are no reoords of action having been taken under this regulation. An illustration of another kind of regulation is seen in'theTublio ^Health Regulations for the United Kingdoms which specifically forbid the^addition to articles of food for sale of any coloring matters whioh are compounds of any of the following metalsj antimony, arsenic, c a d m i u m ^ chromium, oopper, mercury, lead and zinc.Hany of the ioountries have a law for bidding the use of any solder in''the sealing of a food container which selder contains more than 10 percent o f ,lead* It is probably reasonable te believe that, if a product meets all the requirements of the laws of the United States, it is not likely to encounter any difficulty in foreign countries. \\. to you. - \ \' I hope that this information may prove helpful . \: Very truly yours, // \ oo* 'to Mr. Charles Wesley Dunn signed - - George R.
