There has been a dramatic increase in the number of cases of a type of E.coli infection that is most commonly found on farms, the Food Safety Authority of Ireland (FSAI) has warned.

E.coli bacteria live in the guts of humans and animals. Most types are harmless, but some dangerous types can cause severe stomach pains, bloody diarrhoea, kidney failure and even death.

In its mildest form, the symptoms often clear up within around eight days, but children may have it longer. Almost one in 10 symptomatic Irish cases go on to develop kidney disease or kidney failure. Babies and young children are most susceptible to this.

According to the FSAI, so far this year, almost 550 cases of farm-related verotoxigenic E.coli have been recorded, compared to 251 cases during the same period last year.

It is calling on all farmers to ensure that they have ‘robust hygiene practices in place'.

According to FSAI chief executive, Prof Alan Reilly, there are a number of well recognised ways E.coli is spread on farms, such as via contaminated private water supplies and farm animals and their environments.

"Because their immune systems are still developing, babies and young children are most at risk of becoming seriously ill from this infection. It can be easily spread to others such as their siblings or other children in their crèche or at their childminder," Prof Reilly explained.

He described it as ‘vitally important' that special attention is paid to protect children on farms. This includes ensuring children wash their hands properly after being on the farm and not allowing them to drink unpasteurised milk.

"Children suffering from diarrhoea or vomiting must also be kept away from their crèche or childminder until they are clear of symptoms for 48 hours," Prof Reilly added.

The FSAI has published a leaflet, E.coli - How to Reduce the Risk from Your Farm, which offers practical tips and information to farmers. To obtain a copy, call the FSAI's advice line on 1890 33 66 77.
