Retired miner Jim McManus, 70, was admitted to Pinderfields in Wakefield for a routine leg operation in February but fell victim to the deadly bug as a result of the 'disgraceful' state of the ward, they say.
Mr McManus's daughter, Monique Dawson, from Temple Newsam, Leeds, said she even brought her own disinfectant on to the ward to clean around his bed because she was so worried about hygiene standards.
She said she regularly visited her father to find him in tears because he had been left to lie in the blood weeping from an open sore on his leg.
The former Glasshoughton colliery worker was told he would be kept in hospital for three nights for a bypass operation on an artery in his leg.
Although the surgery went smoothly, he was kept in after his scars failed to heal properly and he was eventually told he had contracted MRSA.
His family are now considering legal action against Mid Yorkshire Hospitals NHS Trust over the standard of care he was given.
Tears
The grandfather was also told this week that he must not leave the UK for 12 months because of the condition.
He will not be able to go on a £1,000 Spanish holiday he has booked with his wife and his insurers will not refund the money he has paid for the trip.
Mrs Dawson said: "The conditions he was made to live in were appalling, an absolute disgrace. How anyone who has worked hard all their life and paid their taxes can be treated like is beyond me.
"The ward was constantly filthy and cold, and my dad was left in an appalling state and was very upset.
"We would turn up to find him lying in his own blood and we were always having to ask staff to change his dressings."
She added: "His condition deteriorated and at one point we were sure he was going to die. I have no doubt that the reason he ended up that way was because of the way he was treated on the ward."
Mr McManus said: "I was never in any pain during the time I was there but it was very upsetting to be left to lie there in such discomfort and indignity. This, I was told, would be just a simple operation needing only a few days in hospital.
"But four months later I am still having to go back to hospital for treatment and have this infection hanging over me."
Dr Martin Wale, medical director at the hospital's trust, said: "We are taking the allegations in this complaint very seriously, and it is being thoroughly investigated through our complaints procedure.
"I have spoken with the consultant in charge of Mr McManus's care and he does not recognise the conditions as described on the ward.
"We are reviewing all the issues raised with those who cared for Mr McManus, and will go through them with his family as soon as we have all the facts.
"Tackling MRSA and the prevention of infection is one of our top priorities. We have stringent policies on handwashing and cleanliness in place across our hospitals, together with other measures to reduce the risks of patients contracting MRSA.
"These preventative measures are backed up by systematically reviewing every case of MRSA to establish underlying causes and minimise the chances of it happening again."
