Are Dry Food Storage Containers Safe?

Are Dry Food Storage Containers Safe? - Maria's Condo

In our modern world, where convenience and efficiency are highly valued, dry food storage containers have become an essential part of many households. These containers allow us to store and preserve various dry goods, such as grains, beans, pasta, and cereals, for extended periods. However, concerns have been raised about the safety of these containers and their potential impact on our health. In this article, we will delve into the topic of dry food storage container safety, exploring the advantages and disadvantages of different types of containers and providing practical tips for ensuring the safety of your stored dry goods.


Understanding Dry Food Storage Containers

Dry food storage containers come in various forms, including plastic bottles, cans, glass jars, and airtight bags or boxes. Each type of container has its own advantages and disadvantages when it comes to preserving the quality and safety of stored dry goods. It's essential to understand the characteristics of different containers to make informed decisions about which ones to use for your specific needs.

Advantages of Dry Food Storage Containers

One of the primary advantages of using dry food storage containers is their ability to protect dry goods from moisture, pests, and other environmental factors that can contribute to spoilage. These containers create a barrier between the food and external elements, helping to maintain the quality and freshness of the stored items. Additionally, using dry food storage containers allows for efficient organization and easy access to your dry goods, minimizing food waste and saving money in the long run.

PETE Plastic Bottles: A Budget-Conscious Option

PETE (Polyethylene Terephthalate) plastic bottles have gained popularity as a cost-effective solution for storing dry goods. These bottles, commonly used for soda and juice, can be repurposed for food storage with minimal effort. PETE bottles offer several advantages, including their abundance and availability in various sizes. Gallon-sized juice containers are ideal for storing large quantities of beans and rice, while 2-liter soda bottles are suitable for wheat storage. Smaller PETE bottles, like those used for sports drinks, are convenient for portion-sized storage. Moreover, PETE bottles can be reused multiple times, making them a sustainable choice for long-term storage.

Disadvantages of Dry Food Storage Containers

While dry food storage containers offer numerous benefits, it's crucial to be aware of their limitations and potential drawbacks. Understanding these disadvantages will help you make informed decisions and take appropriate measures to ensure the safety of your stored dry goods.

Limited Oxygen Barrier

One of the primary concerns with dry food storage containers, particularly PETE plastic bottles, is their limited oxygen barrier. While these bottles provide a sufficient oxygen barrier for a couple of years, they may gradually allow oxygen to infiltrate the stored dry goods over time. This oxygen exposure can lead to degradation and a decrease in the shelf life of the products. It's important to note that containers with true oxygen barriers, such as Mylar bags and #10 cans, are more effective in preserving the quality and longevity of dry goods.

Vulnerability to Rodents

PETE plastic bottles, like many other types of containers, are not rodent-proof. If you store your dry goods in an area where rodents have access, it's essential to take additional precautions to protect your food. Consider storing the bottles inside a sealed metal garbage can or placing them in a plastic bucket or tote to prevent rodents from accessing the contents.

Limited Protection from Light

Exposure to light is one of the enemies of food storage, as it can degrade the quality and nutritional value of dry goods. Most PETE bottles do not adequately protect the contents from light exposure. To mitigate this issue, store the bottles in a dark room or place them inside a container that provides sufficient light barrier. Protecting dry goods from light will help maintain their quality and prolong their shelf life.

Selecting the Right Dry Food Storage Containers

When choosing dry food storage containers, it's essential to consider factors such as material safety, oxygen barrier properties, and the type of dry goods you intend to store. By selecting the appropriate containers, you can ensure the safety and longevity of your stored dry goods. Here are some key considerations when selecting containers for dry food storage:

Food Grade Plastic Containers

Using food grade plastic containers is crucial to prevent the transfer of non-food chemicals into your stored dry goods. The U.S. Food and Drug Administration advises against using non-food grade plastic containers, as they may contaminate the food. Look for containers that meet specific regulations to ensure their safety for food storage.

PET or PETE Plastic Bottles

PET or PETE plastic bottles with a recycling symbol number 1 are considered safe for food storage. These bottles provide an acceptable oxygen and moisture barrier for various dry goods, including wheat, dry beans, white rice, pasta, sugar, and rolled oats. Make sure the PETE bottles have lids that screw on tightly to create an airtight seal, ensuring the freshness and safety of your stored dry goods.

Glass Jars and Airtight Containers

Glass jars and airtight containers made from materials like glass, ceramic, or stainless steel are also suitable for dry food storage. These containers offer a higher level of protection from oxygen, moisture, and light. Additionally, they are reusable, environmentally friendly, and do not leach harmful chemicals into the stored dry goods.

Best Practices for Storing Dry Goods

To maximize the shelf life and safety of your stored dry goods, it's important to follow some best practices for storage. These practices will help maintain the quality and freshness of your dry goods, ensuring that they are safe for consumption when you need them.

Proper Cleaning and Preparation

Before storing dry goods in any container, ensure that the container is clean and free from any odors or residues. Thoroughly wash the containers with warm water and mild detergent, rinsing them well to remove any traces of soap. For PETE plastic bottles, check the lids to ensure they create an airtight seal. If you notice any damage or wear, it's best to replace the lids or containers to maintain the integrity of the storage.

Consider Moisture and Pest Protection

Moisture and pests can significantly impact the quality of stored dry goods. To prevent moisture absorption, place moisture-absorbing packets or desiccants in the containers before sealing them. These packets help absorb excess moisture and maintain the dryness of the stored goods. Additionally, consider adding bay leaves or other natural pest deterrents to the containers to prevent insect infestations.

Store in a Cool, Dry Place

Proper storage conditions are crucial for preserving the quality and safety of dry goods. Store your containers in a cool, clean, and dry place, away from direct sunlight, extreme temperatures, and humidity. Avoid storing containers near heat sources or in areas prone to moisture, as these conditions can accelerate spoilage and compromise the safety of the stored dry goods.

Regularly Inspect and Rotate

To ensure the freshness and safety of your stored dry goods, regularly inspect and rotate your stock. Check for signs of spoilage, such as mold growth, unusual odors, or changes in color or texture. If you notice any signs of spoilage, discard the affected container and its contents. Additionally, establish a rotation system to use older stock first, ensuring that your dry goods remain fresh and safe for consumption.


Dry food storage containers play a vital role in our ability to preserve and store a wide range of dry goods. By understanding the advantages and disadvantages of different container types and following proper storage practices, you can ensure the safety and longevity of your stored dry goods. Whether you choose PETE plastic bottles, glass jars, or airtight containers, make informed decisions based on the specific needs of your dry goods and prioritize the safety and quality of your stored food. With proper care and attention, your dry food storage containers can help you maintain a well-stocked pantry and provide peace of mind knowing that you have a reliable supply of nourishing food for you and your family.
