Japanese authorities are warning parents over a rising number of cases of children swallowing button batteries.

Japan’s consumer affairs agency says almost 100 cases have been reported in the last four years, involving 11 hospitalizations.

One child died after swallowing a battery in 2004.

The safety push comes after the US reported 35 deaths involving people swallowing the flat, round cells.

Japanese officials say the batteries can discharge electricity in a child’s throat and even open a hole in the esophagus.

They say parents should bring children to a hospital quickly if they suspect they may have swallowed a button battery.
