HSE warning after Cryptosporidium outbreak

HSE warning after Cryptosporidium outbreak

SHARE

The Department of Public Health Mid-West is advising members of the public to improve handwashing in and around farm settings (wash your hands with hot water and soap), and to test and treat their well water, in order to reduce the risk of infection of Cryptosporidium. 

Public Health Mid-West has managed a Cryptosporidium outbreak linked to a farm setting in the region in recent weeks.

Cryptosporidium is a parasitic disease mainly found in faeces of animals. Infection mainly occurs through contact with farm animals or their environment or when people drink water contaminated with animal faeces, or touch contaminated objects and then touch their mouths before washing their hands.

Alcohol hand sanitiser is not effective against Cryptosporidium, and washing hands with hot water and soap is the most effective form of hand hygiene.

Because it is the start of petting zoo season, there is an increased risk of exposure to Cryptosporidium, especially among children. This is why effective hand washing is crucial.

Symptoms include diarrhoea, stomach pains, and headaches. It may cause outbreaks of gastroenteritis, and can have long-lasting effects on those with weak immune systems.

The Mid-West has also one of the highest rates of Cryptosporidium in Ireland. There were 121* Cryptosporidium cases recorded in the Mid-West region in 2021, almost three times the number recorded in 2020 (46 cases), and the highest over the past 10 years. Incidence of Cryptosporidium peaks in the spring, corresponding with the calving and lambing season.

The Department of Public Health Mid-West and HSE Environmental Health Service Mid-West recently launched an awareness campaign to highlight the need for testing and treating private well water, in order to reduce the risk of serious illness linked to drinking contaminated and unsafe water.

It is important for private well owners to test well water every year and have appropriate protection or/and treatment systems in place. Well owners can avail of grants from their local authorities for treatment, rehabilitation, and the new construction of private wells.

Here are links to local authority grant schemes for private wells in the Mid-West:
