“On September 26, 1961, the 87th United States Congress passed a joint resolution (Public Law 87-319) requesting that the President of the United States proclaim the third week of March National Poison Prevention Week. On February 7, 1962, President John F. Kennedy responded to this request and proclaimed the third week of March as National Poison Prevention Week. The first National Poison Prevention Week was therefore observed in March 1962.”
