I am posting this wondering if anyone knows which beaches are now closed if any due to the wreckage of the Oleg Naydenov ship. See this website for information about the spill if your wondering. I will be travelling here soon. This post can be a running list as this event continues.
Apparently there are images of these beaches being polluted with the oil but reports say so far no official closing of the beaches as stated in the other answer of @pnuts
and finally there is a video of frustrated citizens trying to clean the beach: Youtube Video of Clean Cleaning
As quoted by @pnuts in the above comments.
The link has "The regional government of the Canary Islands has not put in place any restrictions on accessing or fishing off the southern beaches of Gran Canaria." ...
Anyway, a better solution for up-to-date information might be to contact email@example.com
