An expert has warned people to rethink how they store leftover food, cautioning that using foil could have ‘life-threatening’ consequences. During the holiday season, with a surplus of leftovers, many people rely on tin foil to store food in the fridge. However, food scientists are urging a change, saying that foil isn’t completely air-tight, which can allow bacteria to spread and pose health risks.
Dr. Zacharay Cartwight emphasized that aluminum foil cannot create a perfect seal since it is not adhesive, unlike plastic containers or sealable bags that ensure no oxygen reaches the food, keeping it safe for reheating. Poorly stored leftovers can lead to food poisoning, which, although manageable at home in many cases, can sometimes be life-threatening, with symptoms including vomiting, diarrhea, and fever.
In addition, experts have raised concerns over other food storage practices. A recent change by Tesco, replacing plastic lids on hummus pots with non-resealabe covers, has also sparked warnings about improper sealing. Primrose Freestone, a microbiology expert, noted that household fridges often aren’t cold enough to stop harmful bacteria from growing, suggesting freezing as a safer option.
Proper fridge organization can also make a significant difference. Studies show that the average household could save up to £1000 annually by better organizing their fridge, including freezing leftovers and placing items strategically. For example, meats should be stored on the bottom shelf to prevent drips, while dairy products should be placed at the top. Additionally, organizing the fridge properly can improve energy efficiency, reducing electricity costs.
