Officials in the Ministry of Health in French Polynesia have suspended sales of Chinese yoyos.
The children's toy has been ordered off the shelves in Tahiti after reports of children in Madagascar suffering from diarrhoea following use of the toy.
The Tahitipresse news agency quotes ministry officials as saying that parents should be especially careful if the toy is cracked or split.
They say parents and children should wash their hands and consult a doctor if they suffer from diarrhoea, with the yo yo suspected of carrying bacteria.
Toys and other items manufactured in China have been found to carry waste and other animal by-products.
