A Japanese woman in her 60s had her pacemaker settings changed by a rice cooker.

The change was discovered during a regular check-up, but luckily it did not affect her heart condition says the Mainichi Daily News.

Officials of the pacemaker's manufacturer inspected the woman's home, and found that her rice cooker was causing the problem.

The Japanese Health Ministry has issued a warning to people with pace makers to stay away from rice cookers with induction heating systems while they are switched on.
