New York, NY —

Some chocolate milk that went to schools in New York, Connecticut and 2 other states is being recalled. Officials in Connecticut say cleaning solution was found in a batch of the milk that made 8 children sick.

Investigators believe a worker for Guida Milk & Ice Cream accidentally failed to flush the solution from at least one milk-producing machine. The company has apologized and says it's taking action to prevent similar incidents. The company says all its other products are safe.

The tainted milk was half pints of one-half percent, low-fat chocolate milk identified by an April 13th expiration date and product number 138. About 400 cases of the milk were distributed mostly to schools in New York, Connecticut, Rhode Island and Massachusetts.
