A food storage expert has settled the long-running debate over where to store ketchup, warning that keeping it in the cupboard could make you ill. Joshua Houston, a food storage specialist at Household Quotes, says opened sauces must be refrigerated to prevent spoilage and health risks.
Expert Warning on Ketchup Storage
Houston explained: “Bottled sauce is hugely important when it comes to some meals, ketchup with chips is a common sight across the country. No sauce can leave some dishes tasting dry. But ensure that you are storing your sauces properly, the last thing you want is to get ill from consuming something that has gone off. Refrigerating also allows you to get more for your money, as it gives you more time to finish the sauce before binning.”
Martin Bucknavage, a food safety specialist at Penn State University, added: “If you want to maximise the quality of your ketchup, you keep it in the fridge. Once you open up ketchup, there is the potential for mold to get into the top, which is the biggest concern if the product is left out for an extended period of time.”
Heinz Weighs In on the Debate
Heinz, the iconic ketchup brand, also joined the discussion after a survey of 2,000 Brits revealed that four in 10 people store their ketchup incorrectly. Many admitted to keeping their Heinz Tomato Ketchup in the cupboard instead of the fridge. The study showed that people in Sheffield were among the biggest offenders, with nearly two-thirds (62%) confessing to cupboard storage.
Olivia Lennon from Heinz Tomato Ketchup said: “There was only ever one correct answer, and we’re happy to share with Heinz Tomato Ketchup lovers across the UK that our ketchup has to be in the fridge. Although we’re aware many Heinz Tomato Ketchup fans have been storing their ketchup in the cupboard, we do recommend refrigeration after opening. This is the best way to maintain the delicious tangy taste of our Heinz Tomato Ketchup that you know and love.”
History of Heinz Ketchup
Heinz Tomato Ketchup was created by Henry J Heinz in the 1870s and first appeared on US shelves in 1876. Originally called “Catsup,” it was made from five simple ingredients, including sun-ripened tomatoes. Henry soon took “Catsup” international, selling his first product to Fortnum & Mason in London.
If you haven't already moved your ketchup to the fridge, now is the time to do so to ensure safety and quality.
