How long does it take for food to spoil in the refrigerator? Most foods will last 1-2 weeks in the refrigerator stored properly at 40°F or less. High-risk foods like meat and dairy can begin to spoil in 3-5 days. Fruits and vegetables often last 1-2 weeks while bread keeps for 5 days.
As the USDA notes in Keeping Food Safe During an Emergency, your refrigerator will keep food safe for up to 4 hours during a power outage. Keep the door closed as much as possible. Discard refrigerated perishable food such as meat, poultry, fish, eggs, and leftovers after 4 hours without power.
Most foods will last four to 7 days in the fridge.
This is correct, most foods are safe to eat by the 7 day mark if refrigerated. If canned or otherwise preserved, a lot longer than normal until opened and refrigerated.
“It's important to keep the fridge door shut to maintain the temperature inside,” she says. Everything in your fridge typically chills at or just below 40 degrees Fahrenheit (4 degrees Celsius). Temperatures that climb above that level enter what's ominously referred to as the “Danger Zone.”
Bacteria can grow rapidly on food left out at room temperature for more than 2 hours. If food is left out in a room or outdoors where the temperature is 90 degrees F or hotter, food should be refrigerated or discarded within just 1 hour. Myth: When I microwave food, the microwaves kill the bacteria.
Since the compressor has to work harder to maintain the temperature inside the fridge, it puts extra load and pressure. This leads to increased wear and tear on the compressor. This is potentially detrimental to the overall lifespan of the refrigerator leading to frequent breakdowns.
Leftovers can be kept for 3 to 4 days in the refrigerator. After that, the risk of food poisoning goes up. If you don't think you'll be able to eat leftovers within four days, freeze them right away. Frozen leftovers will stay safe for a long time.
Baked Goods and Snack Foods Baked goods and snacks typically have a Use-By Date. Store-bought bread will typically last five to seven days at room temperature, but can last one to two weeks in the refrigerator.
TWO HOURS is the MAXIMUM time perishable foods should be at room temperature (ONE HOUR at temperatures 90 degrees F and higher). This INCLUDES the time they're on the table during your meal. Just ONE bacterium, doubling every 20 minutes, can grow to over 2,097,152 bacteria in 7 hours!
With rumination, the food is undigested. It often still tastes the same as when it was first eaten. The symptoms of rumination syndrome may look like other health conditions or problems. Always talk with your healthcare provider for a diagnosis.
“If meat juice or spoiled food has lingered in an appliance, it may have seeped into the insulation,” Blakeslee said. “At this point, the appliance may need to be discarded.”
Steps to take during a power outage
Keep refrigerator and freezer doors closed. If the doors stay closed, food will stay safe up to: 4 hours in a refrigerator, 48 hours in a full freezer, 24 hours in a half-full freezer.
Although your fridge can still run if its light went out, it is important to identify whether you have a lightbulb issue or an issue with the appliance itself. For example, if your refrigerator door has been open for an extended period of time, many refrigerator lights automatically turn off.
According to the FDA Food Code, all perishable foods that are opened or prepared should be thrown out after 7 days, maximum. No leftovers should survive in your fridge for longer than that. Some foods should be even be thrown away before the 7 day mark.
The bottom line
Although refrigeration slows the growth of most bacteria, they can still grow to unsafe levels and cause a foodborne illness if the food is stored for too long. You should toss leftovers and other cold-kept foods that you open after a maximum of seven days.
Other signs of food spoilage include rising air bubbles (gas), leaking, foam, foul odor, unnatural colors, sliminess, dried food on top of jars, and cotton mold growth (white, blue, black, green) at the top or under the lid (Blakeslee, 2021).
The time it takes food poisoning symptoms to start can vary. Illness often starts in about 1 to 3 days. But symptoms can start any time from 30 minutes to 3 weeks after eating contaminated food. The length of time depends on the type of bacteria or virus causing the illness.
Edwards added that store-bought cakes, which are made to be shelf stable, can last a long time in the fridge, but homemade cakes should typically be consumed in five to seven days.
Discard any refrigerated perishable food (such as meat, poultry, seafood, milk, eggs, or leftovers) that has been at refrigerator temperatures above 40°F for 4 hours or more.
Sanitized eggs can only be out of the fridge for two hours maximum. “If pathogens exist on the food,” he warns, “they can start to proliferate.” At room temperature, bacteria may penetrate washed eggs shells that no longer have their protective coating.
Discard heated leftovers. Thawed cakes, biscuits, breads, fruits and fruit juices are okay to refreeze once if no strong 'yeasty' smell. Thawed snap frozen meat, poultry or fish is okay to refreeze if still below 4°C or transported and handled safely and spent less than 2 hours in temperature danger zone.
