A resident of a San Francisco Bay Area senior citizens home died after being mistakenly served dishwashing liquid as drinking juice, the home said.

Two other residents at the Atria Park of San Mateo were sent to the hospital and are in critical condition, NBC Bay Area reported. The woman was also transported but later died.

"When this occurred, our staff immediately contacted authorities, and the residents were transported to the hospital for evaluation and treatment. We are conducting our own internal investigation and the employees involved have been suspended until this investigation concludes," the senior home said in a statement.

Other details weren't immediately released.

A woman who spoke with NBC Bay Area described the woman who died as a long-time San Mateo resident and mother of nine children.
