Environment Minister Modesto Montoya on Monday said that 2,000 barrels have been recovered. Repsol did not immediately respond to requests for comment on the number of barrels collected.

Chocolate-colored foam bobs on the waters in front of Lima, its appearance a product of the “physical-chemical” reaction between the spilled oil and moving seawater, said Montoya, citing experts from a U.N. multidisciplinary team that has analyzed the spill.

Thousands of fishermen sit idly by, unable to harvest the fish and shellfish they normally extract from the roughly 113 square kilometers (44 square miles) affected by the spill, according to authorities. It is an area larger than the city of Paris.

“We don’t get an answer from anyone, they just give us crumbs” of information, said fisherman Ricardo Estrada, 38, standing on the pier in Ancón, one of 24 polluted beaches on Peru’s coast.

Ancón's beach, which has a boardwalk that is normally bursting with tourists this time of year, is now empty.

“It looks like an empty cathedral,” said Estrada, who has an 8-year-old son and cares for his elderly parents. He looks at a dead seabird that lies on the pier where fish are normally sold.

1 month after oil spill, Lima's beaches empty, cleanup slow

“The animals keep dying,” he said.

Officials say at least 1,200 oil-covered birds have been found, including cormorants, Peruvian boobies, Humboldt penguins, pelicans and seagulls. Peru's National Service for Protected Natural Areas says another 260 birds were found dead.

Peru's government still does not have a full estimate of the economic damage caused by the spill. President Pedro Castillo has changed environment ministers three times amid the environmental disaster, with one minister lasting just three days.

At the end of January, a judge prohibited the local director of Repsol, Jaime Fernández-Cuesta, three company managers and a state official from leaving Peru for 18 months. They are being investigated for alleged environmental crimes.

The unemployed fishermen attended a Mass in Lima’s cathedral last weekend. They brought with them their empty nets and asked the government not to forget them.

The spill took place while crude oil was being unloaded at the refinery from the Italian ship Mare Doricum.

Repsol blames the ship for the spill, but Fratelli d’Amico Armatori SpA, the company that owns the ship, told The Associated Press on Tuesday that “it is important that we do not provide information that is incorrect or misleading.”

“We can confirm that our evaluation of the tests to date shows that all onboard protocols and procedures were followed by the vessel at the time of unloading and from the moment oil was observed in the water,” the Italian company said. The ship has been seized by Peruvian authorities.

Repsol’s La Pampilla refinery is the most important one in Peru and supplies fuel to 40% of the country.
