A concerned Kaitangata resident signalled the alarm yesterday after finding a pile of dead possums and a scattering of dead pigs on the edge of Wangaloa Rd near Kaitangata School.
The man, who declined to be named, described the dump as a "health hazard".
He said he was alerted when he saw a dog roaming around the area.
Upon discovery, he said he believed the dog could have been consuming dead possum.
"Possums carry Tb. People need to be educated about what can and cannot be dumped."
