RIO DE JANEIRO (AP) — Brazil says small amounts of oil from a spill along the northeast coast have reached a national marine park.

Naval and environmental officials said Saturday that oil traces were removed from Santa Barbara Island in the Abrolhos park in the state of Bahia.

Santa Barbara is among five islands in the Abrolhos park, which contains one of Brazil's largest coral reefs. There were no reports that oil had reached the reef.

Oil has washed ashore on some 2,100 kilometers (1,300 miles) of Brazil's coastline for two months, hurting tourism and fishing.

Brazil says the oil is Venezuelan and came from a Greek-flagged ship belonging to Delta Tankers Ltd.

The company denies the allegation, saying it has found no evidence of leakage on the vessel.

After two months of oil mysteriously washing ashore on some 1,300 miles of Brazil's coastline, authorities believe that NM Bouboulina vessel, a Greek-flagged ship belonging to Delta Tankers Ltd. is a suspect, as it was navigating through Brazilian waters at the time and location of the spill.
