The woman's Irish husband remains in intensive care in Paris following the outbreak which has affected a small number of Irish rugby fans.
It is understood the couple travelled to Bordeaux last weekend, to attend Ireland’s opening match in the Rugby World Cup.
Health Correspondent with The Irish Examiner Niamh Griffin said the woman had been discharged from hospital:
"She was in hospital and not recognised that she was having botulism because it's such a rare, rare condition and was discharged from hospital or possibly not even admitted- we're not really sure yet in Bordeaux- and then went to hospital again in Paris where the couple were living."
