The Adeje department for the protection of health, following recommendations issued by the regional department of public health, is advising the public to avoid bathing in the sea where microalgae blooms have appeared in swimming areas of Adeje. Physical contact with the blooms of microalgae, both in the sea and on shore, should also be avoided.
The health department, in co-ordination with the department with responsibility for beaches, has detected the presence of the algae, which appears on the sea surface. The colour is similar to light brown sand, and has been seen along various parts of the island coast line in recent days. These ‘blooms’ of microalgae, which have been seen in bathing zones, have not actually caused any notable damage to date.
Furthermore, the local health department is stating that this is a natural phenomenon produced under certain environmental conditions, the consequence of diverse biological factors, climatic and environmental. The blooms appear sporadically and the vast majority of microalgae are innocuous, although some may product toxins that could affect health, in particular via direct contact, ingestion of water with spores, or inhalation of sea spray.
This council, as a general recommendation, is passing on the advice of the regional department of health, not to bathe in the sea and avoid direct contact with the algae in bathing areas where ‘a change in the colour of the sea water is detected, with spots of intense colour variation, where there is minimum transparency’. If there are beach activities scheduled, the organisers should take these precautions into consideration, and follow the advice at all times of the lifeguards and local police on duty.
The councillor with responsibility for health, Amada Trujillo Bencomo, has been in contact with the Adeje health centre and to date there have been no reported incidences of anyone presenting with injuries or conditions related to the algae.
