I overheard an interesting conversation walking around Tullamore Show at the weekend. Two farmers were queuing for burgers when one turned to the other saying: “You know, no matter which stand it is, all the burgers are the same price.”

The friend seemed more concerned with the burgers on offer and simply nodded.

But the other was determined to have his point heard and continued: “It’s like a burger cartel … I bet they all agree a price together.”

It certainly wouldn’t be the first time I’ve heard claims that a cartel operated in the beef industry.
