Meal preppers (and lazy cooks) have no need to fear. Researchers bust the myths on microwaving food – with tips on how to enjoy leftovers safely.
Making meals ahead of time and then reheating them is a great way to save time in the kitchen and keep food from going to waste. One myth is that food can only be reheated once before it’s no longer safe to eat.
Many food myths don’t have clear beginnings, but some become part of our culture and scientists feel compelled to study them. For example, the “five-second rule” or “double-dipping”
The good news is that meals can be safely reheated more than once as long as you follow a few simple steps when you prepare and store them.
Leftover beef mince is a common sight in many refrigerators. It’s an incredibly versatile ingredient that can be used in tacos, pasta sauces, cottage pies, and more. While reheating leftovers is a great way to cut down on food waste, it does come with some safety considerations. So how many times can you reheat beef mince before it becomes unsafe to eat?
Following Food Safety Guidelines
When it comes to leftovers, the Food Standards Agency (FSA) recommends reheating food only once This helps minimize the risk of foodborne illness. However, if properly stored and handled, beef mince could potentially be reheated a few times while still being safe to eat. The key is following food safety best practices.
According to the FSA, leftover food should be cooled within 1-2 hours and stored in the fridge or freezer To reheat, food must be rapidly heated to 165°F/74°C or steamed until piping hot. The core temperature should be measured with a food thermometer After reheating, food should be eaten right away rather than left to cool and reheat again.
Proper cooling inhibits bacterial growth, while thorough reheating destroys harmful bacteria. As long as these steps are followed correctly each time, the beef mince should retain safety and quality for a few reheating cycles.
Limiting Reheats For Best Quality
While beef mince can technically be reheated several times if handled properly, it’s best to limit the number of reheats for maximum flavor and texture retention.
Each time beef mince is reheated, the quality deteriorates a bit more:
- Texture becomes increasingly dry and grainy
- Flavor dulls and minced beef takes on a more “warmed over” taste
- Fat can separate, leaving greasy pools of oil
- Color darkens from vivid red to unappealing grayish brown
For the best experience, it’s advisable to only reheat beef mince once or twice. Dishes like cottage pie or lasagna with beef mince hold up better to reheating than something like bare crumbled mince.
If reheating minced beef often, add extra sauce or gravy to keep it moist. Stirring in additional fresh herbs before serving also livens up the flavor.
Storing in Portions
Pre-portioning beef mince into individual servings can help reduce the need for multiple reheats.
When cooking a large batch of cottage pie, bolognese sauce, or chili, divide it into meal-sized portions before freezing. Thaw only what you need and reheat a single portion at a time.
This approach gives you the convenience of leftovers without compromising too much on texture and taste. It also allows better monitoring of safe storage times.
Reheating Tips
To safely reheat beef mince while retaining moisture and flavor, follow these tips:
-
Use a microwave, stovetop, or oven instead of a slow cooker to quickly reheat above 165°F/74°C
-
Stir frequently and add splashes of water or broth to prevent drying out
-
Heat mince dishes thoroughly until piping hot, stirring occasionally
-
Add extras like spices, herbs, gravy, or sauce to boost flavor
-
Only reheat what you plan to eat within 2-3 days and don’t re-chill reheated portions
-
If refrigerating again after reheating, use within 3-4 days
-
For improved food safety, limit reheats to 1-2 times max
When to Toss Out Leftovers
It’s important to also know when to throw away beef mince leftovers:
-
Mold growth, sliminess, or off odors indicate spoilage
-
More than 4 days in fridge or 2-3 months in freezer
-
Reheated 3+ times
-
Not fully reheated to safe internal temperature
-
Looks dried out or tastes unpleasantly sour
Following proper storage, handling, and reheating guidelines will allow enjoying beef mince leftovers safely. But it’s also vital to recognize when it’s time to discard the mince and make a fresh batch.
Reheating Other Meats
Similar rules apply when reheating other cooked meats like chicken, pork, lamb, or sausage. Always reheat fully to 165°F/74°C and toss when any signs of spoilage arise. Limit reheats to 1-2 times for best quality.
Some delicate seafood like shrimp or fish don’t hold up as well to reheating. It’s best to eat them freshly cooked when possible.
When reheating any leftovers, proper food safety is key. Handle cooked meat carefully, reheat thoroughly, and store appropriately to get the most from your leftovers.
Why can food make us sick?
There are many ways bacteria and viruses can end up in foods. They may occur naturally in environments where products are harvested or contaminate foods during processing.
Viruses won’t grow in foods and will be destroyed by cooking (or proper reheating). On the other hand, bacteria can grow in food. Not all bacteria make us sick. Some are beneficial,including probiotics in yoghurt or starter cultures used to make fermented foods.
But some bacteria are not desirable in foods. These include those that reproduce and cause physical changes, making food unpalatable (or spoiled), and pathogens, which cause illness.
Some pathogens grow in our gut and cause symptoms of gastroenteritis, while others produce toxins (poisons) which cause us to become sick. Some bacteria produce special structures, called endospores, which survive for a long time – years, even – until they encounter favourable conditions which allow them to grow and produce toxins.
While cooking and reheating will generally kill pathogenic bacteria in foods, they may not destroy toxins or endospores. When it comes to reheating foods, toxins pose the greatest risk of illness.
The risk is higher for foods that have been handled badly or cooled down too slowly after being cooked or heated up the first time. This is because these conditions may let bacteria that make toxins grow and multiply.
Bacteria that cause food-borne illness typically grow at temperatures between 5C and 60C (the “temperature danger zone”), with fastest growth occurring about 37C.
“Potentially hazardous” foods are those that allow these bacteria to grow the most. These include dishes with meat, dairy, seafood, cooked rice or pasta, eggs, or other protein-rich ingredients.
Staphylococcus aureus, which many people carry in their noses or throats, is often the cause of food poisoning from reheated foods. It produces a heat-stable toxin that causes vomiting and diarrhoea when ingested.
Food handlers can transfer these bacteria from their hands to foods after cooking or reheating. Staphylococcus aureus will grow and make poisons if the tainted food is kept in the temperature danger zone for a long time. Subsequent reheating will destroy the bacteria but not the toxins.
