More than 100 cows, sheep and goats arrived in the Southwestern peninsula late yesterday, in what residents believe to be an illegal cargo.
The animals were seen sitting on the Southern Main Road near Icacos up to dusk.
Most of the cows appeared to be high bred Zebu and Holstein and most likely came from the South American mainland.
Some of the cows believed to have been brought to the Southwestern Peninsula from South America.
Residents who requested anonymity said the animals were posing a health hazard in Icacos.
The herd first began showing up earlier this year.
"One morning we woke up and saw these big breed animals sitting on the road in front our houses," the source said.
The animals are being brought in on pirogues up a deserted river in Gran Chemin.
"We are concerned because this poses health risks. We have had instances of Hand, Foot and Mouth disease. These animals are not quarantined," the source added.

The animals are also posing a traffic hazard to motorists and school children.
Usually by morning butcher trucks would show up in the peninsula and the animals would disappear within hours, the source added.
Since the closure of the Cedros Breeding Unit there is no place to impound the animals so the police are turning a blind eye because there is no place to put the cows.
