Food Storage : This Common Mistake Encourages Harmful Bacteria Growth

Trends

We all strive to store our food properly, whether it’s to keep it fresh for longer or to avoid unnecessary waste. But what if I told you that some of the most popular food storage methods, despite being widely recommended, might actually be doing more harm than good?

We’ve all heard about how great vacuum sealing is for food storage, especially when it comes to preserving freshness and flavor. However, recent warnings from experts suggest that this technique might not be as foolproof as it seems.

Vacuum Sealing: Not a Miracle Method After All

Vacuum sealing has become a go-to method for keeping food fresh for longer, with claims that it can be more hygienic than freezing and even eliminate 80% of bacteria. These kinds of promises are tempting, right? After all, if something can make food last longer while eliminating harmful bacteria, it sounds like a win. But according to Océane Sorel, a virologist and expert in food safety, these claims are far from the truth.

In a recent social media post, Sorel pointed out that vacuum sealing, while useful in many ways, does not actually kill bacteria. Instead, it simply slows down bacterial growth by removing oxygen from the packaging. This is where things get tricky. While bacteria may not grow as quickly in a vacuum-sealed environment, they’re still present. And as soon as the food is exposed to air again, the bacteria can quickly reactivate, causing potential risks like food poisoning.

The Risk of Dangerous Bacteria

One of the biggest concerns with vacuum sealing is that certain types of bacteria thrive in low-oxygen environments—and vacuum sealing can actually create the perfect conditions for these harmful microbes. The Clostridium botulinum bacteria, for example, is responsible for causing botulism, a rare but potentially deadly foodborne illness. This bacteria thrives without oxygen, and vacuum sealing can unintentionally provide the ideal setting for it to grow.

It’s easy to overlook this risk, especially when vacuum sealing is marketed as a “safe” method of food preservation. But Sorel stresses that it’s crucial to understand that vacuum sealing doesn’t replace the need for proper refrigeration or freezing. It’s not a one-stop solution for food safety—especially for perishable foods like meats and dairy.

What You Need to Do After Vacuum Sealing ?

If you’re still keen on using vacuum sealing as part of your food storage strategy, there are a few things you need to keep in mind to ensure you’re using the method safely. First, it’s important to remember that after vacuum sealing your food, it must be stored in the fridge or freezer immediately. This ensures that the environment remains cold enough to prevent bacteria from growing, even in the absence of oxygen.

Another tip: always check the bags you’re using to vacuum seal. Even small holes in the bags can compromise the effectiveness of the sealing process, allowing bacteria to get in and contaminate the food. So, before you seal your items away for storage, give the bags a good check to ensure there are no imperfections.

A Better Way to Store Your Food

While vacuum sealing can be an excellent tool for extending the life of certain foods, it’s not a catch-all solution. For perishable items, it’s essential to use it alongside proper refrigeration or freezing. By combining techniques—like vacuum sealing for longer storage and keeping items chilled in the fridge or freezer—you can help reduce food waste and keep your meals safe.

As for those of us who are trying to be more mindful about the food we buy and consume, it’s helpful to remember that food storage is not just about convenience. It’s about being conscious of how we keep our food safe and how we use the right methods to protect our health.

If you’re unsure about the best food storage methods for your kitchen, don’t hesitate to consult with experts or trusted sources, like food safety organizations, to make sure you’re on the right track. After all, our health should always come first.


By adjusting our approach to vacuum sealing and taking extra care with the way we store our food, we can make a positive impact on both food safety and sustainability. It’s always worth questioning common practices to ensure we’re protecting our health and reducing risks—because when it comes to food storage, ignorance isn’t bliss.
