Nestlé has issued an international recall for certain batches of its baby formula products, over concerns that they could contain a harmful toxin that triggers nausea and vomiting.

BBC News reports that although there have been no confirmed cases of illnesses linked to the product, the batches believed to have the toxin were sold in France, Germany, Austria, Denmark, Italy and Sweden among other countries. In a statement released on January 6, Nestlé said that it has been in contact with authorities in affected countries, and assured parents and caregivers that "appropriate actions" are being taken to ensure the health of families and their babies.

"Food safety and the wellbeing of all infants remain our top priority," Nestlé said. "We understand that this news may cause concern, and we are committed to providing clear, transparent information and support for parents and caregivers throughout this process. "

The company believes that oils used in certain batches of baby formula were contaminated by a toxin known as cereulide, produced from bacteria, and resistant to heat, which can cause severe or persistent vomiting, diarrhea and unusual lethargy, all of which would occur between 30 minutes and six hours after initial exposure. Nestlé noted that the toxin's presence in oils is extremely uncommon, and said that it is working with its oil supplier to conduct a "full root-cause analysis."
