What do supermarkets do with left over food?
As a general rule, grocery stores try to reduce the amount of leftover food that they end up with, since unsold food generates no money for the store. There are a number of techniques used to reduce expired food, and to dispose of it, but it is often donated, composted, or thrown out.
Fresh meat is typically kept in grocery stores for 10-14 days. Frozen meat, on the other hand, can be stored for up to a year. But you might be wondering if supermarket meat is any better than butcher meat.
Is supermarket meat previously frozen? Not all. Generally speaking, most grocery stores sell some frozen and some fresh meat. The nicer and more high-end a store is, the more likely they are to have in-house butchers who cut the meat at the store.
They use the meat's color as a guideline to determine the food's freshness. But, many meat manufacturers actually inject the food with carbon monoxide to give it that fresh, reddish-pink look.
Butcher shops and meat departments can sell (for a very low price) their bones, fat, and other inedible meat scraps to rendering companies that will turn the unwanted waste into proteins for pet food and other industrial uses. This is circle-of-life stuff; the kind that maybe you don't want to know about.
Like perfectly good fruit and vegetables, meat and seafood are thrown out before their best before dates by grocery stores, supermarkets and other distributors.
Carbon monoxide MAP artificially extends the cosmetic appearance of fresh meat. The FDA considers the use of carbon monoxide to be a color stabilizer, not a “color additive”, because it stabilizes (not changes) the typical red color of fresh meat.
What Nitrites Do. Nitrites keep meat red by bonding to the myoglobin and acting as a substitute for the oxygen. Oxygen and sodium nitrate both turn myoglobin red, but nitrate attaches with a more stable bond and so the color lasts longer.
Generally speaking, butcher meat is also fresher and higher quality than meat purchased at a supermarket. Rather than being pre-cut, pre-packaged, and laid out until someone decides to purchase it, butcher's meat is often cut right in front of the customer.
That's understandable. Supermarkets are responsible for 10% of all U.S. food waste – that's 43 billion pounds annually. According to the Guardian, the food supply chain wastes 45% of all produce, 35% of seafood, 30% of cereals, and 20% of meat and dairy products every year.
Is 5 year old frozen meat still good?
According to the USDA, frozen foods are safe to eat indefinitely. But just because something is ok to consume doesn't mean it will still taste delicious after years in a deep freeze.
Whatever the meat — beef, chicken, pork, or fish — there's no question about it: You can safely store your food the longest in the freezer. That's because you can safely freeze meats indefinitely.

Plumping, also referred to as “enhancing” or “injecting,” is the process by which some poultry companies inject raw chicken meat with saltwater, chicken stock, seaweed extract or some combination thereof.
It turns out, it's not actually blood, but rather a protein called myoglobin, according to Buzzfeed. The protein is what gives the meat and its juices a red hue, and it's perfectly normal to find in packaging.
This darkening is due to oxidation, the chemical changes in myoglobin due to the oxygen content. This is a normal change during refrigerator storage. Beef that has turned brown during extended storage may be spoiled, have an off-odor, and be tacky to the touch and should not be used.
The website uses the latest and most accurate live statistics on the state of the planet. As at the time of writing, TheWorldCounts said Earth will run out of food in 27 years and 249 days. Citing Harvard sociobiologist Edward Wilson, it added that there are limits to Earth's capacity to feed humanity.
Cultured or lab-grown meat is obtained by harvesting cells from muscle fibers, called myocytes. These cells can be cultured in a bioreactor to artificially create the meat that animals produce in their bodies.
Lab-grown meat doesn't come from slaughtering animals. Instead, it comes from harvesting the cells of a living animal. In fact, cells taken from a single cow can produce an astonishing 175 million quarter-pounder burgers.
There is also a possibility of becoming ill from bacteria, especially in the summer; the dumpsters themselves breed bacteria and some are sprayed with pesticides.
After grinding, the surface of beef appears bright red, which is likely the point when the product contains the most oxygen. As oxygen decreases, uncooked ground beef will slowly change to dull red to tan and eventually brown. Those changes occur primarily because of a loss of oxygen.
Do butchers add water to meat?
There is no added water in any fresh, unprocessed beef. Beef is washed during slaughter, but the small amount of water would be absorbed on the surface of the meat, not bound to the protein or inside the tissue and would quickly evaporate or drip out. Beef is often ground while partially frozen.
Myoglobin stays unchanged and red as the meat juices flow, then turns from red to gray-brown as the release of moisture ends and the meat becomes dry. Because myoglobin exposed to air eventually turns brown, red surfaces on raw meat also signify freshness.
Nearly all of the blood is drained from a carcass within the first few minutes of the harvest process. Myoglobin is the heme-iron containing protein found in muscle that stores oxygen and gives meat its color.
When meat is fresh and protected from contact with air (such as in vacuum packages), it has the purple-red color that comes from myoglobin, one of the two key pigments responsible for the color of meat. When exposed to air, myoglobin forms the pigment, oxymyoglobin, which gives meat a pleasingly cherry-red color.
The USDA uses a purple dye stamp on all cuts of meat to grade it properly and as a sign of inspection.
In general, when grocers like Walmart sell ground beef or other cuts at the meat counter, they're selling someone else's finished product and slapping their brand on it. Currently, Walmart mainly buys its beef from Cargill and Tyson—two of the world's largest commodity meat companies.
When purchasing meat and poultry, it's important to use your senses of touch, smell and sight. Always make sure the meat is firm to the touch, and check that they packaging doesn't have any tears, holes or excessive amounts of liquid. It should also be cold to the touch and have no odor.
Prime. U.S. Prime is the highest quality available and makes up only 2 to 3% of the available beef on the market. This generally is sold to high-quality hotels and restaurants and is the most expensive, if you are purchasing for personal use.
China and India produce more household food waste than any other country worldwide at an estimated 92 million and 69 million metric tons every year, respectively. This is unsurprising, considering both countries have by far the largest populations globally.
Here's some “food” for thought: While the world wastes about 1.4 billion tons of food2 every year, the United States discards more food than any other country in the world: nearly 40 million tons — 80 billion pounds — every year.
What does Costco do with food waste?
We include Waste to Energy as part of our diversion program. Other diversion examples include donations, anaerobic digestion, recycling, composting and animal feed.
Information. Ground beef is safe indefinitely if kept frozen, but it is best if used within 4 months. Refrigerate or freeze ground beef as soon as possible after purchase. This preserves freshness and slows the growth of bacteria.
All that ground beef underneath the top layer has no access to oxygen, so it turns an unappealing color of gray. This will also happen to any beef you store in the freezer.
But we're here to finally put the question to rest, as the USDA states that as long as all foods are stored at 0 °F or lower in your freezer, they are safe to eat indefinitely.
You can freeze virtually all foods (with the exception of some, e.g. eggs in the shell which expand and crack). Food can remain frozen indefinitely and technically be safe to eat, as bacteria will not grow. However, over time all frozen food will deteriorate in quality and become unappetising to eat when defrosted.
If kept frozen continuously, chicken will be safe indefinitely, so after freezing, it's not important if any package dates expire. For best quality, taste and texture, keep whole raw chicken in the freezer up to one year; parts, 9 months; and giblets or ground chicken, 3 to 4 months.
To determine how long frozen ham lasts and maintains its quality, here's what foodsafety.gov says: Fresh, uncured, uncooked ham: 6 months. Fresh, uncured, cooked ham: 3 to 4 months. Cured, cook-before-eating ham (sliced or whole): 3 to 4 months.
Grocery stores share excess food while saving on garbage disposal fees and receiving a tax incentive. The donations help Second Harvest diversify its menu. Kroger anaerobic digester.
Redistributing surplus food
Good food should never go to waste. So, at the end of every day, our stores donate surplus food to charities and communities through our Community Food Connection scheme.
We work with food banks and regional charities to ensure any good food left at the end of every day gets to people who need it. Our Community Food Connection scheme, which links local charities to our stores, is the biggest of its kind in the UK. It provides two million meals a month to charities and community groups.
How much of food gets thrown away from supermarkets?
Grocery Store Food Waste
About 30 percent of food in American grocery stores is thrown away. US retail stores generate about 16 billion pounds of food waste every year. Wasted food from the retail sector is valued at about twice the amount of profit from food sales.
In FY2022, we donated more than 696 million pounds of food in the U.S. alone. Finally, if food is no longer edible, we work to convert it to animal feed, compost or energy.
Some is given away to food banks, some sold to salvage stores and the rest taken by people who scrounge outside supermarkets. With the current economic troubles, expired foods are increasingly becoming a part of America's diet.
The first reason is liability.
Many vendors mistakenly believe they'll get sued for providing food that gets somebody sick, even if they think that food is safe. The vendors may decide giving away their leftovers isn't worth the legal risk.

What foods are the best leftovers? Soups top the list at 79%, followed by pizza (63%), meat (62%), pasta (60%) and rice (55%).
They reuse it. In order to maximize profitability, some restaurants re-use left over food the next day in the same or different recipes. Some do use leftovers for employee meals.
Some of it goes into staff meals, but restaurants throw away almost 94 percent of their excess food—most of which ends up in landfills, where it releases methane gas that contributes to global warming. The resources used to produce that food also go to waste.
