Fifty guests at a diamond wedding party in Wolverhampton were struck down with Norovirus prompting a city-wide alert to GPs.
The outbreak of the bug occurred after the anniversary party in Tettenhall. Everyone is understood to have now recovered but guests had to answer questions from doctors and the Health Protection Agency.
Wolverhampton City Council said tests of food samples indicated it was a viral infection and nothing to do with the venue itself or caterers.
The Health Protection Agency (HPA), Wolverhampton City Primary Care Trust and the council worked together to establish the cause of the 50 cases of diarrhoea and vomiting and confirmed it was Norovirus.
