Prosecutors in Paris have opened investigations into five baby formula manufacturers after several issued mass recalls over concerns their product contained a toxin.
Nestle, Lactalis, Danone, Babybio and La Marque en moins will be probed over whether there was any criminal wrongdoing in distributing baby formula that may have been contaminated with cereulide.
French authorities have received complaints from eight individuals who reported their child vomited after consuming baby formula.
Last week, Nestle and Danone issued recalls in more than 60 countries, including the UK, over potentially contaminated batches.
At least 36 infants in the UK have suffered from suspected food poisoning after consuming baby formula, officials have said.
