Liquid egg whites are pasteurized; and it’s always helpful to ensure pasteurization works, unless this is post-processing contamination.

BBC News reports bottles of liquid egg white, used by bodybuilders and bakers, have been linked to seven cases of salmonella in the UK, according to the Health Protection Agency.

The bug causes diarrhoea, vomiting, abdominal pain and fever. One patient needed hospital treatment.

The affected batch – an own-brand product by Myprotein – has been recalled.

The source of the eggs used in the batch is still being traced.

A similar outbreak connected to liquid egg white in 2007 affected 70 people.
