Animal entrails in Sutton Bridge fly-tipped waste
Animal entrails have been found in fly-tipped waste at Fields Farm North beside the A17 at Sutton Bridge.
The spot has been targeted at least twice - with witnesses reporting fly-tipping on January 26 and February 17.
Council vice-chairman Simon Booth said: "There were actually some animal entrails in the rubbish, which is quite concerning."
He said the site was cleared one day and the next week the fly-tipping started again.
Coun Booth understood the internal drainage board had experienced a similar problem at another site.
"It looks as though someone has been doing a bit of butchering on the quiet and getting rid of the carcasses," he said.
Former parish councillor Vicky Hills twice spotted the illegal dump, including at least nine black bags among other waste on February 17.
She said "disgusting materials" had been dumped by "irresponsible people who have no social conscience".
Mrs Hills added: "I am really perplexed because it appears to be household waste that is collected weekly by South Hollahnd District Council, which is an excellent service."
The former parish councillor spotted the fly-tips while out walking her dogs, but didn't know what was inside the bags.
Parish councillors are warning residents not to attempt to clear fly-tipped waste because it may contain hazardous materials - and, where waste is dumped on a road, they say people could put themselves in danger.
Coun Michael Booth reminded members about an incident where asbestos was dumped, and said the district council had to bring in a specialist firm to clear it.
