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, Danone and Lactalis, triggering recalls in dozens of countries and raising concerns among parents.

“The new threshold will be of 0.014 micrograms of cereulide per kg of body mass, compared to 0.03 micrograms per kg currently,” the ministry said in a statement.

“France’s move follows a EU meeting on Jan 28 and is in line with an updated guidance from the European Food Safety Authority that will be released on Monday,” it said.

“The lower threshold is likely to lead to further withdrawals in France in the coming days,” it added.

The recalls illustrate how a single compromised ingredient can spread through the infant nutrition supply chain, despite tight regulation, and cause rapid market jitters.

French investigators said on Jan 23 they are looking into whether there is a link between the death of two infants and recalled formula products.

On Thursday, consumer group foodwatch said it had filed a criminal complaint in Paris on behalf of eight families whose babies it says fell ill after consuming contaminated infant formula, claiming companies waited too long to warn the public.
