Separation from Covidien
In 2011, Covidien announced plans to spin off its pharmaceuticals business into a standalone public company. Mallinckrodt Plc was officially separated as of June 28, 2013. Trading of regular shares of the company’s stock on the New York Stock Exchange began on July 1, 2013, under the ticker symbol MNK.
In 1867, the Mallinckrodt brothers, Gustav, Otto and Edward, founded G. Mallinckrodt & Co. in St. Louis, Missouri. Mallinckrodt Chemical Works was incorporated 15 years later. By 1898, the company had established itself as a pharmaceuticals supplier and in 1913 became the first to introduce barium sulfate as a contrast media for x-rays.
Nuclear waste in St. Louis, Missouri
Henry Farr and John Ruhoff, technical managers for Mallinckrodt, Inc. were directed by Edward Mallinckrodt, Jr. to develop a chemical process for purifying large quantities of uranium. Uranium purified by Mallinckrodt was used at the University of Chicago Chicago Pile-1, the first nuclear chain reaction. Mallinckrodt also contributed uranium to the Manhattan Project, producing fissionables used in the atomic weapons detonated over Hiroshima and Nagasaki. From 1942 to 1957 Mallinckrodt purified 50,000 short tons (45,000,000 kg) of uranium products at various locations in and around the city of St. Louis. The waste was secretly dumped on Coldwater Creek and in various St. Louis suburbs, including Berkeley, Hazelwood, Bridgeton, and Weldon Spring with the approval of the federal government, which is now taking financial responsibility for the cleanup. The dumping substantially contaminated Coldwater Creek.
Cleanup efforts are now underway by the Army Corps of Engineers. Cleanup sites include the St. Louis Downtown Site (SLDS), where uranium was refined; the St. Louis Airport Site (SLAPS), where waste produced at SLDS was stored; the Hazelwood Interim Storage Site (HISS), where waste from SLAPS was improperly relocated; and the St. Louis Airport Site Vicinity Properties (SLAPS VPs), areas where contamination was caused by relocation of waste. Additional nuclear waste was also illegally deposited at the West Lake Landfill, which has now been designated a Superfund site. Various buildings have been decontaminated and demolished and nuclear material has been excavated and shipped out of St. Louis by covered rail as part of the cleanup process, yet more nuclear waste remains in and around St. Louis.

Until 1966, Mallinckrodt processed uranium for nuclear weapons at its main plant along the Mississippi River in downtown St. Louis and in Weldon Spring, 25 miles to the west. Under the cover of national security secrecy, the Government authorized the company to dump radioactive wastes quietly in the suburbs, including a 21-acre Berkeley field owned by St. Louis. It is that field and the 61-acre park across the street that the Government is considering for a permanent storage site.
