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

The team at Netherhall Herefords, north of Kirkby Lonsdale, said 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."

"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."

Netherhall Herefords have lost livestock through the inadvertent eating of balloons and lanterns.

"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."

Having taken their concerns to social media, the farm was met with an outpouring of support, with many people sharing their own experiences.

One person said: "It makes me so angry because it's littering the planet on top of being harmful to animals - there have to be better ways to remember people or celebrate birthdays."

Another commented: "Folk have no idea where they end up - if they want to commemorate a loved one, why not plant a tree or scatter wild flower seeds?"
