- Freeze food before it goes bad: If you know you won’t be able to consume all of your perishable food before it goes bad, consider freezing it. Freezing food can extend its shelf life and prevent it from going to waste.
- Meal planning: Planning your meals ahead of time can help you use up your food before it goes bad. Make a grocery list of ingredients you already have on hand and plan meals around those items.
By taking these steps, you can save money on food waste and stretch your budget further. It’s important to be mindful of the food you have and how to properly store it to ensure that it lasts as long as possible.
Factors That Affect How Long Food Lasts Without Power
Temperature: One of the most critical factors that affect how long your food will last after a power outage is the temperature of the food. If the food’s temperature rises above 40 degrees Fahrenheit, it becomes susceptible to bacterial growth and can go bad quickly.
Type of food: Another factor that affects how long your food lasts without power is the type of food. For example, dairy products like milk and yogurt spoil much faster than other food items, like canned goods.
Length of power outage: The length of the power outage is another important factor to consider when determining how long your food will last. The longer the power is out, the higher the chances are that your food will spoil.
Environmental Temperature
Temperature is a major factor that affects how long food lasts during a power outage. The ideal temperature range for most perishable foods is between 40 and 140 degrees Fahrenheit. When the temperature rises above 40 degrees, the bacteria in the food start to multiply rapidly, which can lead to foodborne illness.
Another important factor to consider is the duration of the power outage. Food can remain safe in the refrigerator for up to four hours without power, as long as the door is kept closed. In a freezer, food can last for up to 48 hours if the freezer is full and 24 hours if it is half full.
The type of food also plays a role in determining how long it can last without power. Foods with high water content, such as fruits and vegetables, tend to spoil faster than foods with low water content, such as hard cheeses and cured meats. Additionally, cooked foods tend to spoil faster than raw foods.
Foods That Go Bad Fast After a Power Outage
Meat and Poultry: Meat and poultry are highly perishable and are at high risk of spoilage after a power outage. Bacteria can grow quickly in these products, leading to the risk of foodborne illness.
Dairy Products: Dairy products such as milk, cheese, and yogurt also have a short shelf life and require refrigeration to stay fresh. Without power, these products can quickly spoil and become unsafe to eat.
Seafood: Seafood is highly susceptible to bacterial growth and can spoil rapidly. Without proper refrigeration, the risk of foodborne illness from consuming seafood increases significantly.
Dairy Products
Butter: Butter can typically last 1-2 days without power. If the room temperature is higher than 70°F, then it will not last as long.
Cheese: Cheese should be thrown away if it has been above 40°F for more than 2 hours. Soft cheese can be a breeding ground for bacteria and spoil quickly.
Milk: Milk can last up to 4 hours without power if the room temperature is below 70°F. After that, it needs to be consumed quickly or thrown away. Milk is also very sensitive to temperature fluctuations, so it is best to check the temperature before consuming.
It’s important to remember that dairy products can harbor harmful bacteria that can lead to foodborne illness. It’s best to err on the side of caution and throw away any dairy products that have been exposed to warm temperatures for an extended period of time.
Meat, Poultry, and Seafood
Perishable items such as meat, poultry, and seafood are the most susceptible to spoilage and bacterial growth. After four hours without power, these items should be discarded, especially if they are not stored in airtight containers. When it comes to meat, the USDA recommends keeping it at 40°F or below to prevent bacterial growth.
Ground meat and poultry tend to spoil faster than whole pieces, so it’s important to be extra careful when dealing with these items. They should be cooked or frozen within two hours after a power outage to reduce the risk of foodborne illness.
Seafood, especially shellfish, should also be consumed quickly or frozen to avoid spoilage. Even if it smells okay, it may still be unsafe to eat. When in doubt, throw it out.
Cooked Foods
Cooked meats and poultry: These should be discarded if they have been above 40°F for more than 2 hours, or if they have an unusual odor, color, or texture.
Cooked rice, pasta, and potatoes: These should be refrigerated within 2 hours of cooking, and should not be left out at room temperature for more than 2 hours. If left out for longer than this, they should be discarded.
Cooked vegetables: These should be refrigerated within 2 hours of cooking, and should not be left out at room temperature for more than 2 hours. If left out for longer than this, they should be discarded.
Tips on How to Tell if Food is Still Safe to Eat After Power Loss
Smell the food. If it has a sour, rancid or unusual odor, it’s likely spoiled and unsafe to eat.
Check the texture of the food. If it’s slimy or sticky, it’s a sign of bacterial growth and spoilage.
Look for discoloration or mold on the food. If there are any visible signs of mold or discoloration, it’s best to discard the food.
Use a food thermometer to check the internal temperature of the food. If the temperature is above 40°F for more than two hours, it’s not safe to eat.
When in doubt, throw it out. It’s always better to err on the side of caution and discard food that may be unsafe to eat.
Check for Signs of Spoilage
After a power outage, it’s important to check for signs of spoilage before consuming any food. Odor is a good indicator of spoilage. If the food smells sour or off, it’s best to discard it. Texture is also a factor to consider. If the food feels slimy or has a strange texture, it may have gone bad. Color is another indicator of spoilage. If the food has changed color or has visible mold, it’s best to discard it.
When in doubt, it’s better to be safe than sorry. If you’re unsure whether a particular food is safe to eat, it’s best to err on the side of caution and throw it out. Consuming spoiled food can lead to foodborne illness, which can be dangerous and even deadly in some cases.
If you’re still unsure whether a particular food is safe to eat, you can use the USDA’s FoodKeeper app to determine the safety of different foods after a power outage. This app can provide information on how long different types of food can be safely stored at room temperature, as well as tips on how to properly store and prepare food to prevent spoilage.
How to Keep Your Food Safe During a Power Outage
Power outages can be stressful and disruptive, especially when it comes to keeping your food safe. Here are some tips to help you minimize the risk of foodborne illness:
Have a plan: Make a plan for what you will do with your food in the event of a power outage. Consider purchasing a generator or having a backup plan to keep your refrigerator and freezer cold.
Keep the doors closed: Keep your refrigerator and freezer doors closed as much as possible to maintain the temperature. A refrigerator will keep food cold for about 4 hours if the door is kept closed, while a full freezer will maintain its temperature for about 48 hours.
Use a cooler: If you have a cooler and ice available, use it to keep perishable items cold. This is especially important for items like milk, meat, and eggs.
Keep non-perishables on hand: Keep a supply of non-perishable items on hand, such as canned goods and shelf-stable snacks, in case the power outage lasts longer than expected.
Use a food thermometer: Use a food thermometer to check the temperature of perishable items before consuming them. Food that has been above 40°F for more than 2 hours should be discarded.
Keep the Fridge and Freezer Closed
If you experience a power outage, the first rule of thumb is to keep your fridge and freezer doors closed. Opening the doors allows warm air to enter, which can cause the temperature to rise and spoil your food quicker. As per the United States Food and Drug Administration (FDA), a refrigerator can keep food cold for about 4 hours, while a freezer can maintain its temperature for up to 48 hours if it is full and 24 hours if it is half-full.
If you know you will experience a power outage, you may want to take steps to prepare. You can fill empty space in your freezer with water bottles or bags of ice to keep the temperature lower for a more extended period. Also, you can consider investing in a battery-powered fridge thermometer to keep track of the internal temperature.
If your freezer is not full, you can transfer the contents to a cooler filled with ice. Ensure the cooler has a tight-fitting lid and keep it in a cool, dark place. This way, you can keep the contents at a safe temperature while you wait for the power to come back on.
Use an Appliance Thermometer
Know the Temperature: Make sure you have an appliance thermometer in both your fridge and freezer. This will help you monitor the temperature and determine if the food is still safe to eat. Keep the thermometer in the coldest part of the fridge and freezer.
Check Regularly: Check the thermometer regularly to ensure that the temperature is still below 40°F in the fridge and 0°F in the freezer. If the temperature is above this, discard any perishable food.
Buy a Battery-Operated Thermometer: If you live in an area prone to power outages, consider purchasing a battery-operated thermometer for your fridge and freezer. This will ensure that you can monitor the temperature even if there is no power.
Don’t Rely on Appearance: Just because the food looks and smells fine, it doesn’t mean it is safe to eat. Always rely on the temperature to determine if the food is still safe.
Have a Backup Plan: If the power outage lasts for an extended period, have a backup plan to store your perishable food. This can include using a cooler with ice or moving the food to a neighbor’s fridge or freezer.
Have a Backup Plan
Despite your best efforts to keep your food safe during a power outage, it’s always a good idea to have a backup plan in case the outage lasts longer than expected. Here are a few things you can do:
Buy Dry Ice: Dry ice is a great option for keeping your freezer cold for an extended period. It can be found at most grocery stores, and a 50-pound block can keep a full freezer cold for up to two days.
Have a Cooler Ready: Keeping a cooler on hand and stocked with ice packs can help keep perishable items like milk, eggs, and cheese cool for a short period.
Have Non-Perishable Foods on Hand: Stock up on non-perishable items like canned goods, peanut butter, crackers, and granola bars, so you have something to eat in case the power outage lasts longer than expected.
Consider a Generator: If you live in an area that experiences frequent power outages, it may be worth investing in a generator to keep your appliances running during an outage.
Common Myths About Food Safety During Power Outages
Myth #1: If the power is out for less than 4 hours, the food is safe. While it’s true that some foods can stay safe in the refrigerator for a short time, it’s best to err on the side of caution and discard any perishable food that has been above 40°F for more than two hours.
Myth #2: Putting food outside in the snow will keep it safe. The outside temperature can fluctuate and lead to unsafe temperatures for food. Additionally, animals and bacteria can contaminate the food.
Myth #3: You can tell if food is safe by its smell or taste. The smell or taste of food is not always an accurate indicator of safety. Pathogenic bacteria may not alter the taste or smell of the food, and some toxins may not be noticeable at all.
Myth #4: Freezing food kills bacteria. Freezing does not kill bacteria, it just puts them in a dormant state. When the food is thawed, the bacteria can become active again, potentially causing illness. Always cook frozen food to the recommended temperature to ensure safety.
“If it Looks and Smells Fine, it’s Safe to Eat”
One of the most common myths about food safety during a power outage is that if the food looks and smells fine, it must be safe to eat. However, this is not always true. Bacteria that cause foodborne illness can grow in food without causing any noticeable changes in appearance or odor.
Even if the food looks and smells fine, it’s important to check the temperature of perishable items such as meat, poultry, seafood, and dairy products. If these items have been stored above 40°F for more than two hours, they should be discarded.
It’s also important to remember that some types of bacteria can cause illness even in small numbers, so it’s best to err on the side of caution and throw out any food that may be unsafe to eat.
“Putting Food in the Snow Will Keep it Cold Enough”
One of the most common myths about keeping food safe during a power outage is that putting it in the snow will keep it cold enough. However, this is not true. While snow can provide a temporary solution, it is not a reliable way to keep food safe.
Why? Because snow can melt quickly, especially if the temperature rises above freezing. Additionally, snow can be contaminated with bacteria and other harmful substances.
What to do instead? It’s best to use coolers or insulated bags with ice packs to keep your food cold. These can keep your food at a safe temperature for several hours, even without power.
Remember: It’s important to keep your food at a safe temperature of 40°F or below to prevent the growth of harmful bacteria. Don’t rely on the snow to keep your food safe during a power outage.
