Police are being urged to take action against a woman seen dumping raw chicken on fields used by dog walkers.
There have been several reports of raw meat being left on fields in Crosland Moor over recent weeks.
Kirklees Council environmental health officers are investigating the allegations and have appealed for people to come forward with information.
In one case school chef Liz O’Neill found slices of chicken with safety pins fastened through them.
People have expressed fears that someone is deliberately out to harm dogs or other animals.
Liz, 34, who regularly walks dog Marley on fields at Dryclough Recreation Ground, has been on alert and always scans the area for more dumped meat.
She was left shocked and angry on Sunday afternoon when she saw a woman dumping pieces of chicken in the field.
Bizarrely, the woman was throwing the meat over her shoulder and was then seen washing her hands from a bottle of water.
“I couldn’t believe it,” said Liz. “I saw this woman come in with a couple of bags in her hand and started throwing all this stuff over her shoulder.
“As I ran down towards her she was washing her hands from a big bottle of Buxton water.
“She started rushing out of the fields and I said to her: ‘You can’t do that. Why are you doing that?’ She just kept saying: ‘I am sorry, sorry.’
“I followed her and said this wasn’t normal and she then claimed not to speak English.”
The woman, who was also thought to be carrying scissors, went back to pick some of the meat up but Liz took some home and plans to contact Kirklees Council’s environmental health department.
The woman was photographed from an upstairs window by a neighbour as she hurried off and pictures have appeared on social media. It is thought she went to a nearby house.
Liz immediately rang police and was later told there was nothing they could do as no offence had been committed.
In a text message to Liz police said: “This is not a matter that the police would deal with. Therefore if you could inform Kirklees environmental department they should be able to advise you.”
Liz said: “I can’t believe the police aren’t interested. They said because no-one has been hurt they can’t class it as a crime.
“The least they should do is talk to this woman to find out what’s going on. Maybe at least now it will stop.”
In March 2014 the Examiner reported how dozens of drawing pins were scattered over the same playing fields which are used by a dog club, the Springers Agility and Flyball Club, and local football teams.
There was also a spate of contaminated meat found dumped at several Huddersfield beauty spots popular with dog walkers.
A police spokesman said: “West Yorkshire Police are aware of the incidents involving raw meat being left in public places.
“This is not a matter which is dealt with by the police and anyone with any concerns is asked to contact Kirklees Council’s Environmental Department.”
A spokesman for Kirklees Council said: “Council officers are investigating these allegations and will be working closely with its partners in community safety and the police to minimise harm to animals and the public.
"If anyone has any evidence of the dumping of waste meat they should contact the council on 01484 414739.”
