Tomato ketchup is under threat from climate change.
Scientists have claimed that global warming could be responsible for the dinner-time favourite disappearing from plates.
A team of Danish experts say that the global harvest of tomatoes will halve, with the varieties used in ketchup set to be the worst affected.
The researchers stated: "These are two types of cultivated tomato - one for fresh consumption, usually grown under controlled environments.
"And one for industrial transformation known as processing tomatoes, usually grown under field conditions."
They added: "Processing tomatoes are important because they are used for tomato paste, tomato sauce, ketchup and other tomato-derived products."
A six per cent decline in tomato production is predicted by 2050 as soaring temperatures will result in the varieties used for ketchup being put under increasing stress from the heat.
The boffins have predicted that the harvest could be halved in the worst-case scenario.
