We have received a communication from Mr. A. H. Mitchell Muter, F.I.C., Public Analyst for Lambeth, with reference to the contamination of cheese as the result of it being wrapped in tinfoil.—Mr. Muter observes that the following facts are those upon which he based his remarks, re the potential danger to health arising from contamination by tin in cheese wrapped in this metal, contained in his report for the fourth quarter of 1929 to one of the Local Authorities for which he acts :—On 4th November, 1929, a Food Inspector to the Authority in question submitted an informal sample of wrapped cheese as the result of a complaint having been received from a ratepayer to the effect that he had been taken ill after partaking of it.—Mr. Muter's analysis showed it to contain 5·68 grains of tin per lb., and he therefore reported that he was of opinion that the ratepayer was fully justified in bringing the matter to the notice of the Inspector.—On 15th November a formal sample of wrapped cheese was submitted, which he found contained 6·89 grs. tin per lb., and he issued a report to this effect. As the result of this report he received on the 25th November five informal samples of various brands, all of which were found to contain tin varying from 0·28 to 6·34 grs. per lb., and a further three informal samples received on the 3rd December contained tin in quantities from 1·37 to 11·03 grs. per lb. On the 12th December a formal sample was submitted which contained as much as 14·8 grs. tin per lb.
