Meat stolen from supermarkets is being sold at cut price rates in pubs.
The North West neighbourhood police team (NPT) has called on landlords to help stamp out the problem.
The number of thefts of meat being reported by shops and supermarkets has increased in the past month.
Police believe the majority of it is being either stolen to order or to be sold on to others.
The Co-op supermarkets in Ossett and at Broadmeadows in Outwood have been targeted as well as Tesco on Dewsbury Road in Ossett.
Temporary Insp Mark Chamberlain, pictured, said: “We are appealing for information about where the meat is being sold. We know it is quite often sold on in pubs but we want to know which ones.
“I would appeal to landlords to keep their eyes open and for people to pass on any information. Some people may think this is a victimless crime but it is not and we are determine to bring offenders to justice.”
