'Hundreds of thousands of people in Lancashire are being warned to boil their tap water before use to kill a microscopic bug. Tests at a water treatment plant have found traces of cryptosporidium, a parasite which can cause gastroenteritis and is commonly associated with diarrhoea, vomiting and nausea.
The warning was issued on Thursday afternoon to United Utilities customers across large parts of Lancashire including Blackpool, Chorley, Fylde, Preston, South Ribble and Wyre.
The water firm is advising the customers to boil their water for all drinking, food preparation and teeth brushing as a precaution until further notice. Residents can continue to use tap water without boiling for general domestic purposes such as bathing, flushing toilets or washing clothes.'
