The government of Mauritius has refuted claims that oil pollution from the grounded bulker Wakashio has been killing marine mammals.
The MOL-chartered capesize got stuck on a reef in July, breaking in two in August and spilling 1,000 tonnes of fuel.
Experts examined the bodies of two of 18 melon-headed whales, also known less commonly as electra dolphins, found between Pointe-aux-Feuilles and Grand-Sand on the south-east coast in the last week.
Another eight anmials of the same species were found in the lagoon of Bois-des-Amourettes and Pointe-aux-Feuilles, and another body was discovered nearby.
In total, 35 bodies have been found.
"Early results do not indicate that these animals have succumbed to the effects of the fuel spill following Wakashio's grounding," according to the ministry of blue economy, marine resources, fishing and maritime services.
Jaw injuries found
Autopsies found no traces of hydrocarbons, either in the breathing system, skin, face or stomach.
"The stomach of autopsied marine mammals was empty but these animals carried serious jaw injuries. Pieces of fat and skin have been collected for further analysis, including DNA tests," the ministry said.
Bite injuries were seen on most carcasses.
No atypical odour emerged from the skin of the carcasses and each oral cavity was checked.
No liquid was found in chest and abdominal cavities, and the dissected intestines turned out empty.
"However, all samples taken will be subject to bacteriological and toxicological tests. Toxicological analysis will be carried out at Forensic Science Laboratory," the ministry added.
Full results are expected in the next few days.
