A salmonella cluster in Wrexham has prompted an investigation to find the cause and prevent further cases.
Public Health Wales (PHW) is working with Wrexham council’s environmental health team and Betsi Cadwaladr health board to investigate.
PHW said the strain Salmonella Typhimurium can cause bloody diarrhoea, vomiting and stomach pain.
Most people who contract the bug usually recover but complications can occur among frail or very young people.
PHW has asked anyone who is worried about their health to call their GP or NHS Direct Wales on 111
