A no-contact advisory was issued for the Kalamazoo River after a chemical spill occurred at Pfizer's manufacturing plant in Kalamazoo, Michigan.

According to city health officials, Pfizer released over 1,057 gallons of methylene chloride in its manufacturing facilities processing area, which was then discharged into the Kalamazoo River.

Methylene chloride is a colorless liquid that Pfizer and other pharmaceutical manufacturers use as a solvent in their pharmaceutical medicines.

After the chemical spill occurred, Kalamazoo County Health Officials warned residents not to come into contact with the Kalamazoo River.
