"The most recent analyses [of the water] revealed that the microbiotic levels are within the reference parameters of normal, so the advice against bathing was lifted," the same official told Lusa.

The commander of the Port of Sines stressed that Zambujeira do Mar beach, whose bathing was banned on Friday, "can be frequented again".

Zambujeira do Mar beach was banned from bathing on Friday after the presence of the coliform bacteria Escherichia coli (E.coli) was detected in the water, Rui Filipe revealed that day.

At the time, in statements to Lusa, the commander Rui Filipe, advanced that, that morning, the red flag had been hoisted by lifeguards, to prevent bathing on that beach.

The ban was due to the fact that it had been "detected the presence of E.coli [bacteria] in the water, at levels above the appropriate for bathing", through samples collected by the Portuguese Environment Agency (APA), which is done regularly.

Then "a second collection" of water samples from that bathing area, whose results have been disclosed today allow the ban on bathing to be lifted.
