Cryptosporidium was the causative agent of a gastroenteritis outbreak that occurred in the city of Turiazon over the weekend of September 9-10 and subsequently spread to the three other locations mentioned above.

Starting that week, Tarazona residents could not use oral water or brush their teeth and had to boil the water for at least 10 minutes before cooking. To this end, 10 drinking water tanks in the city of Zaragoza, affected by the contamination of the water of the Queles River with protozoa of the genus Cryptosporidium, have been filled. Each tank can hold 1,000 liters of potable water and, taking into account the number of inhabitants in each city, one has been installed in each town of Torreras, Los Fayos and Novalas, and seven in Tarazona.
