According to the U.S. Department of Agriculture, Americans throw away close to 26 tons of food per year, almost 25% of the food purchased for home use. A study conducted by the University of Arizona found that Americans spend about $43 billion dollars a year on food that is eventually wasted. Scientists also have found that decomposing food in our landfills creates large amounts of methane gas, which contribute to global warming. In addition, the Center for International Energy and Environmental Policy says that more energy is wasted in discarded food than is produced from all of the oil and gas extracted from the United States coastlines.
Interestingly enough, one of the biggest causes of food waste in our country is the expiration date that is placed on food containers.
For example, the “use by” date refers to the date that the unopened item is at its best as far as quality of taste and appearance is concerned. As time passes the “use by” date, the degradation of food is gradual. The “sell by” date has nothing to do with the taste or actual quality of the food, but it indicates that the store should remove the product from sale due to the expected beginning of a decline in quality. According to ShelfLifeAdvice.com, Americans are most wary of dairy products, such as milk, eggs, mayonnaise, cheese and yogurt.
ShelfLifeAdvice.com lists some handy guidelines.
Milk, if properly refrigerated, will remain safe about a week after the “sell by” date. Cottage Cheese lasts for 10-14 days past the date on the container. Mayonnaise, unopened, can last 30 days after the expiration date; yogurt about a week or so. Lastly, refrigerated eggs should last about 3-5 weeks after the ’sell by’ date. As far as my personal procedure for food quality, I open and sniff. If the food passes the sniff test, I taste. If I don’t gag, I eat. You may want to try a different method! But consider employing a method that is more thoughtful than the automatic ‘throw away at the container date’ method. It could save the planet unnecessary waste and save you a good amount of money.
