It has emerged that three people who caught Salmonella and were at Birmingham's Heartlands Hospital have died.
In total, 43 people in the West Midlands have caught the food poisoning bug, 34 of them connected with the Heartlands Hospital.
A Hospital spokesperson, said:
One of the deaths is subject to a coroner’s inquest and therefore we are unable to comment at this stage.
We can confirm that we have tested both food and water at the Heartlands site and have ruled these out as the root cause of the infection.
We are working with the Public Health England to investigate the other two cases, which includes the possibility of the infection being community acquired.
