Investigations are still going on into the outbreak of a rare gastro-intestinal bug in Ilkley last year.

Almost 60 people in the area were diagnosed with the giardia lamblia bacterium between September and December last year and health chiefs put local GPs an alert to look out for symptoms of the illness.

The Health Protection Agency and Bradford Council’s Environmental Health Department worked with Bradford and Airedale Teaching Primary Care Trust in a bid to trace the source of the outbreak.

The trust has confirmed this week that no more cases have come to light, but investigations are still going on.

A spokesman said: “The Health Protection Agency and Bradford Council’s environmental health department are continuing to investigate the cause and source of the outbreak.”
