The Food Safety Authority of Ireland has confirmed that batches of bottled water have been withdrawn from some supermarkets.
The withdrawal applies to water from one particular source.
It is understood low levels of coliform were found to be present in three brands of bottled water produced by Shannon Minerals and stocked by Superquinn, Aldi and Lidl.
The FSAI confirmed there is no risk to public health but there had to be a trade withdrawal in the past fortnight.
Shannon Minerals stressed that no faecal coliform contamination was found in the water and said it posed no risk to consumer health
In a statement, Superquinn said that routine surveillance had revealed 'very low levels' of coliform in three brands of water produced by Shannon Minerals.
It says it withdrew the products from sale as precautionary measure.
Aldi also said it had withdrawn water from sale following tests.
It said tests were carried out by the HSE on a batch of 6 pack 750ml bottle Comeragh Springs Spring Water.
‘While the quality level posed no threat to human health, the HSE advised all product from the tested batch be removed from shelves,’ Aldi said.
