French anti-fraud officers have raided Perrier bottling and laboratory sites owned by Nestlé as part of an investigation linked to allegations surrounding the treatment of natural mineral water in France, according to Reuters.

The raids were carried out yesterday, 19 May, at two of its water facilities in Vergèze, southern France, where Perrier is bottled, as well as at a laboratory in the Vosges mountains.

“We continue to cooperate fully with the relevant authorities,” a Nestlé spokesperson said in an emailed statement cited by Reuters.

According to Reuters, the raids form part of an investigation launched after a consumer group filed a complaint with the Paris prosecutor alleging “deceit”. French broadcaster Radio France first reported the development.

France’s anti-fraud department declined to comment, while the Paris prosecutor’s office did not immediately respond to requests for comment, Reuters reported.

Perrier and several other mineral water brands have faced scrutiny since French media reports in 2024 alleged that producers had used water treatment methods intended to prevent contamination, potentially conflicting with regulations governing products labelled as natural mineral water.

A French court rejected a separate consumer group case against Perrier in late 2025.

FoodBev has reached out to Nestlé for additional comment.
