You might want to think twice before throwing away your food.
. But there is currently no difference between the date labeling used on these foods and that used on more stable food items.Infant formula is the only food product with a “use by” date that is both government regulated and scientifically determined. It is routinely lab tested for contamination. But infant formula also undergoes nutrition tests to determine how long it take the nutrients - particularly protein – to break down.
Microbial studies, like the ones we food safety researchers work on, are also a scientific approach to meaningful date labeling on foods. In our lab, a microbial study might involve leaving a perishable food out to spoil and measuring how much bacteria grows in it over time. Scientists also do another kind of microbial study by watching how long it takes microbes like listeria
after intentionally adding the microbes to food to watch what they do, noting such details as growth in the amount of bacteria over time and [when there’s enough to cause illness].Determining the shelf life of food with scientific data on both its nutrition and its safety could drastically decrease waste and save money as food gets more expensive.
