Mystery pills found in cereal box

Weet-Bix manufacturer Sanitarium is investigating the discovery of a packet of mysterious tablets in a cereal box.

The Weet-Bix was bought at a Palmerston North supermarket for a softball tournament at a youth camp and was opened by one of the young players.

The girl who found them said they were in a sealed packet sitting on top of the cereal.

Sanitarium nutrition manager Kim Stirling told the Manawatu Evening Standard the company would analyse the tablets and check the supply chain.

"We need to find out how it got in -- at our factory, at distribution level, the supermarket or after they had been bought."

The ziplock packet contained nine pills of three different kinds, with no markings.

Parent Karen Welford said the find was a shock.

"We had a four year old there. If he had opened the box, he would have just gobbled them down thinking they were lollies," she said.
