A salmonella outbreak affecting at least 23 victims has forced the Heartlands Hospital in Birmingham to close down eight wards as a leading public health lawyer calls for a probe into what caused the infection.
The Heart of England NHS Foundation Trust has confirmed that four of its staff and 19 patients have tested positive for a common strain of salmonella.
Amandeep Dhillon, a leading public health lawyer, has called for an investigation into the outbreak.
Mr Dhillon said the "unusual" outbreak, which has left eight people in a stable condition at Birmingham's Heartlands Hospital, might provide lessons to help prevent future outbreaks.
"Attention will then need to turn to identifying the cause of the infection. This will be essential to provide victims and their loved ones with the answers they will want as to what caused their illness," Mr Dhillon said.
Symptoms of salmonella include diarrhoea, stomach cramps and sometimes vomiting and fever.
Sainsbury's says it has immediately withdrawn 500g bags of SO Organic sultanas from its shelves after "low levels of salmonella were found during routine testing".
Food safety is our top priority so we immediately took this product off display and, as a precautionary measure, we are asking customers who have bought these sultanas to return them to their nearest Sainsbury’s store where they will receive a full refund.
We apologise to customers for any concern and inconvenience this causes.”
An outbreak of salmonella is being investigated in north west Wales, health officials said today.
A statement from Public Health Wales said a total of 22 people had been diagnosed with salmonella since mid July, with five of the cases requiring hospital treatment.
The outbreak is centred in Conwy and Gynedd.
"Anyone who lives in, or has visited, north west Wales since the middle of July and is experiencing diarrhoea, stomach cramps, vomiting and fever should contact their GP or NHS Direct Wales on 0845 4647," the statement urged.
The Food Standards Agency are searching for the source of the eggs used in the egg whites product infected with Salmonella.
The Health Protection Agency has said there has been no national increase in the number of people infected with Salmonella poisoning as a result of the new cases detected, but they are investigating:
"Although there has been no increase in the number of cases of this type of Salmonella over recent weeks we are still investigating whether newly identified cases might be related to this egg product."
This is the second case of Salmonella linked to liquid egg whites, in 2007 a similar outbreak affected 70 people in England, Wales and the Chanel Islands.
This egg product has been subject to a recall and so we hope that now that it is no longer in circulation that this will stop people becoming unwell. If anyone has any of this batch of product at home then they should dispose of it.
