FARMERS have issued a warning to the public with balloons threatening the lives of their cows.

Livestock are at risk of consuming the plastic of the balloons, with two cows having already died as a result in the past.

A farm spokesman said: "Our cows are going out to calve next week and we are picking up three or four balloons a week.

"One was being chewed inside the shed this morning."

While the issue may at first appear innocuous, the owners outlined just how serious it has the potential to be.

"Cows and calves are curious and will chew and swallow them, resulting in a certain and very painful death," they added.

"Please don't buy them [balloons] and especially don't let them go - they will also harm and kill other animals."

"We've noticed this problem for the last five years but it has been steadily getting worse - and it has been really bad this year," they said.

"We lost a calf who had ingested plastic and a cow which had swallowed wire, which we suspect came from lanterns that had landed on the fields - these were both found during the post-mortem."
