MEXICO – Gulf of Mexico oil slick stretched hundreds of miles, harming wildlife and reaching Mexican protected areas

April 1, 2026

Mexican authorities confirmed that an oil spill detected in early March spread across more than 600 kilometers (373 miles) of the Gulf of Mexico. Roughly 200 kilometers (125 miles) of coastline in Veracruz and Tabasco were affected, and oil reached seven federally protected natural reserves. The spill became a public issue after criticism over the government’s slow and limited release of information.

A preliminary investigation by the Mexican Navy identified three separate origins of the spill:

An anchored vessel near the port of Coatzacoalcos in Veracruz.
A nearby natural oil seep, referred to as a chapopotera, located about 8 kilometers (5 miles) off the same port.
A second natural seepage in the Bay of Campeche, near the Cantarell oil fields.

Admiral Raymundo Morales explained that the ship responsible has not yet been identified because 13 vessels were sailing in the region at the time and still need inspection. He also confirmed that at least one source of leakage remains active, adding that natural seeps in Cantarell have recently released higher-than-usual amounts of hydrocarbons.

Although officials have downplayed the likelihood of severe environmental harm, the spill affected multiple ecosystems.

Seven protected areas in Veracruz and Tabasco reported contamination.
The National Commission of Natural Protected Areas documented the presence of hydrocarbons in reserves such as the Los Tuxtlas Biosphere Reserve, Veracruz Reef System National Park, and the Centla Wetlands.
Six species—among them fish, coastal birds, and sea turtles—were found contaminated.

According to the ocean conservation group Oceana, communities along the Gulf of Mexico Reef Corridor reported deaths of sea turtles, a manatee, various fish species, and damage to 17 coral reefs.

Authorities have so far collected approximately 430 tons of hydrocarbons as part of ongoing cleanup operations. The spill comes just five months after another incident in Veracruz, where heavy rains and flooding caused a pipeline rupture that polluted an eight-kilometer stretch of the Pantepec River.
