A year earlier the farm had been issued with a prohibition notice by the Health and Safety Executive because it was failing to prevent or control the risk of exposure to cryptosporidium.

The owners of the farm, which has now stopped its open days, declined to comment when approached by the BBC but have previously said they had "made every precaution possible" to prevent an outbreak.Many farms across the UK have had to diversify their businesses over recent years to boost their profitability, with public open days, petting farms and play barns becoming an important source of income.
But inspection reports released to the BBC under the Freedom Information Act by the UK's national cryptosporidium reference unit show that a small number of farms are not meeting health and safety standards - and, in extreme cases, are ignoring warnings from inspectors.
On one farm in Wales, which was linked to a number of outbreaks, inspectors found sick animals kept on display and a lack of handwashing facilities, risk assessments and staff training.The Department of Health and Social Care, covering England, said the pay rise on the table was the second above inflation increase for NHS staff in the last 10 months.

Resident doctors in England are already being balloted on strike action over pay. Other health unions are organising votes on the pay awards.All this may cast a shadow over a government 10-year plan for the NHS in England due in the next few weeks.
