A 30-year-old man and his three-year-old niece were diagnosed with salmonella on a family farm in Kildare last year, the Health Protection Surveillance Centre has revealed in a report.

They both drank unpasteurised — or raw — milk produced by cows on the farm before contracting salmonella.

The warning comes as new legislation is to be introduced in Ireland later this year banning the sale of unpasteurised milk.
