More Salmonella 'mysteries' on the Northern Beaches

'Mystery' has struck again. Sand contaminated with Samonella paratyphi B var java was found again on the Northern Beaches playgrounds. "Hitchcock Park at Avalon and Winnererremy Bay at Mona Vale on the Northern Beaches have been fenced off for the second time this year, while a third South Avalon playground has not re-opened since May". Replacing (some) of the sand did not work. The bug, linked to exotic fish/pets can cause serious illness.

In pet-fanatic Manly off leash dogs mingle in playgrounds and on the beaches with toddlers. Apart from community hygiene standards and enforcements, it does not instill confidence that possible bio hazards could also turn out to be 'mysteries' for half a year or more...
