MEXICO CITY (AP) " Mexico has hired 80 workers to clean up thousands of dead fish that piled up on Gulf coast shores in Matamoros, near the Texas border.
The massive fish die-off was most notable on the Costa Azul beach. Mexico's commission for natural protected area said Friday the die off was caused by red tide.
Red tide is caused by elevated levels of a marine biotoxin contained in algae blooms.
The bloom was first notice farther north on Sept. 13, and by Sept. 17 had reached Mexican shores.
The commission said levels continue high. The neurotoxins in red tide can cause paralytic shellfish poisoning.
