Nestle NESN.S widened an infant formula recall to include a new batch of Guigoz formula after France lowered the maximum cereulide toxin threshold, the Swiss group said on Wednesday.

Cereulide, which can cause nausea and vomiting, has been detected in ingredients from a factory in China supplying a large number of baby formula makers including Nestle and France's Danone DANO.PA and Lactalis, triggering recalls in dozens of countries and raising concerns among parents.

"As methods for analyzing cereulide have evolved, we are voluntarily recalling a batch of Guigoz infant formula in addition to the batches already recalled," Nestle said on its recall alert.

The company had already recalled some Guigoz batches, among other brands, in France in January and December.
