Spar has ordered a product recall of bottled water in the South West of England after discovering that the 500ml bottles of Silverbrook Falls water contain pseudomonas aeruginosa bacteria.

Spar is recalling a batch of the bottles,  sold singly or in 6 x 500ml multipacks with the use by date of Jul 2015 MS1A L13199. A spokesman for Spar said: “If you have bought SPAR Silverbrook Falls Water 500ml with this date code and identification please do not consume it, but contact the store you purchased it from for a full refund.”

Pseudomonas aeruginosa bacteria is found widely in soil and stagnant water, and can infect humans and plants. It does not usually cause illness in healthy people, but is described as an “opportunistic” organism, causing serious infection when normal immune defences are weakened such as with cancer treatment and some hospital patients.
