An investigation is under way after more than 700 staff are thought to have become ill following their annual company Christmas dinner.

Health officials in France said workers at Airbus Atlantic’s site in the west of the country suffered from vomiting and diarrhoea.

The ARS health agency has not revealed what was on the menu at the event, which was held last week.

An investigation was being launched to find the source of the mass food poisoning, the organisation told the AFP news agency.

Airbus Atlantic, a subsidiary of aerospace group Airbus, employs 15,000 people in five countries.
