This recommendation is perfectly aligned with the official food safety guidelines from reference agencies such as the USDA (United States Department of Agriculture) and the FDA. These institutions rely on a solid consensus of experts and observational data to recommend a strict limit of 3 to 4 days for the storage of perishable cooked dishes. Indeed, while refrigerator cold slows the multiplication of microorganisms, it does not stop it entirely. Certain bacteria invisible to the naked eye can continue to develop at low temperatures without altering the smell, taste, or visual appearance of the food, which makes our senses deceptive. Jessica Knurick's advice is therefore fully scientifically validated and constitutes a common-sense rule for preserving the vitality and comfort of our digestive system on a daily basis.
