Morrisons is recalling 170g packets of trimmed beans after two customers - who live 200 miles apart - found needles inside the vegetables.
The shocking - and potentially dangerous discovery - happened over the Easter weekend.
Mum-of-three Sarah Parry found a metal needle inside the bean while eating it, reported the Manchester Evening News .
She said: “I felt something sharp in my mouth, and it had actually got stuck in my gum.
“I pulled it out and it was a needle! I honestly could not believe it."
Meanwhile Margret Lynch from Glasgow said she discovered 12 needles inside her veggies whilst she was cutting them up.
Morrisons has removed the packets from shop shelves across the country and is investigating the incidents.
If you have bought the beans - which have a sell-by-date of May 5, 2017 - do not eat them and instead return the packet to your nearest Morrisons store for a full refund.
A Morrisons spokesperson said: “We have been made aware of two incidents involving metal being found in two packets of green beans.
"The health and safety of our customers is our top priority, so as a precaution, we are recalling the products and are continuing with our investigation.
"The relevant authorities have been informed and we are also talking to the two customers.”
