The two dogs were dead within hours of each other while a third suffered severe discomfort over the weekend of September 11-12.

The three animals had in common to have walked on the beach of Saint-Efflam in Plestin-les-Grèves (Côtes-d'Armor), a place often lined with green algae.

Suspecting algae to be the cause of the death of the two dogs, the Safeguarding Trégor-Goëlo-Penthièvre association then carried out analyzes on one of the two deceased animals.

The results have just fallen and they exclude, for the time being, the trail of green algae to explain the death of the two dogs.

"The analyzes failed to identify traces of hydrogen sulfide in the lung sample," according to a press release from the association relayed by

France Bleu Armorique

.

Hydrogen sulfide is a poisonous gas released by decaying algae that is potentially fatal to humans and animals.

"Not irrefutable proof that the animal was not poisoned"

However, the association believes that these results do not provide "irrefutable proof that the animal was not poisoned".

"Because the organic sample took place at the time of the animal's death two days after the supposed intoxication on the beach, which leaves plenty of time for the animal's lungs to exhale the hydrogen sulfide molecules while breathing healthy air, ”emphasizes the association.

Pending the results of additional analyzes, its members are still calling for a protocol to be instituted each time a death or illness occurs in an area affected by green algae.

"Failure to respond favorably to this request can only be assimilated to a refusal to shed light on this type of accident and thus maintain doubts about the cause of death of victims of the green tides to better exonerate those responsible. and recognized for this tragic pollution that Brittany has been carrying for fifty years, ”the press release concludes.
