A fourth-grade boy is dead, and his mother is in a coma, in Changchun, Northeast China's Jilin province, after consuming a beverage produced by a subsidiary of Coca-Cola on Tuesday, according to a Beijing News report.

The police say organic phosphorus, a toxic pesticide, has been found in the Guoli Naiyou (strawberry flavor drink).

Guoli Naiyou is a mix of milk, juice and fruit particles manufactured by Minute Maid, which is owned by Coca-Cola Co.

Two other people in Changchun were sent to the hospital recently after drinking the beverage, police said, but they have recovered.

Coca-Cola Jilin Beverage Co Ltd said Wednesday that nothing abnormal turned up in an internal quality test, adding that it will cooperate with the official investigation.

Meanwhile, quality supervision authorities who are conducting the investigation have ordered the product off supermarket shelves.
