§ Mr. Peter Thomas
There was no formal Press statement. Information given by my Office on 25th June related to further analyses undertaken by the laboratory of the Government Chemist, subsequent to the answer I gave my hon. Friend the Member for Barry (Mr. Gower) on 15th June, when I reported that tests down to a limit of 0.02 parts per million had failed to detect PCBs. The further analysis of milk samples from Maendy and Brofiskin detected PCBs below this limit, the highest level found in Maendy milk being 0.015 parts per million and in Brofiskin milk 0.003 parts per million. I am advised that PCBs at this level are of no public health significance.
