Storing kibble in a plastic container is a common practice, but it may not be the best option for your pet's health. While it is convenient and easy, there are several potential downsides to consider. Firstly, plastic containers can become greasy from the oils in kibble, and if not washed properly between refills, the fresh food can become contaminated with rancid oils and toxins, leading to possible health issues for your pet. Additionally, some plastics can leach harmful chemicals like BPS and phthalates into the food, which have been linked to serious health issues. To avoid these issues, it is recommended to store kibble in its original bag, placed inside an airtight container, preferably made of stainless steel, as it is easier to clean.

Plastic containers can leach harmful chemicals into kibble
While plastic containers are a convenient option for storing kibble, it's important to be aware of the potential risks associated with them. Plastic containers can leach harmful chemicals into kibble, which can have negative health impacts on pets.
Plastics, even those that are BPA-free, can leach chemicals such as BPS and phthalates into pet food. These chemicals have been linked to serious health issues in pets, including hormone disruption, obesity, diabetes, and even cancer. The leaching of chemicals occurs due to the porous nature of plastic, allowing the oxidizing fats from the kibble to seep into the plastic and contaminate the food. This contamination can result in increased free radical activity, leading to health concerns such as hair loss, malnutrition, liver disease, and cancer.
To minimize the risk of chemical leaching, it is recommended to keep the kibble in its original bag and then place the entire bag into the plastic container. This creates a barrier between the kibble and the plastic, reducing the chances of direct contamination. Additionally, it is crucial to wash and dry the plastic container thoroughly between refills to remove any residual fats or toxins that may be present.
Some sources suggest using alternative materials for kibble storage, such as glass or stainless steel containers. These materials are less likely to leach harmful chemicals and are considered safer options for pet food storage. However, finding glass containers large enough to store kibble can be challenging.
Overall, while plastic containers are commonly used for storing kibble, it is important to be aware of the potential risks associated with chemical leaching. By taking precautionary measures, such as keeping the kibble in its original bag and practicing proper container hygiene, pet owners can help reduce the chances of their pets being exposed to harmful chemicals.

Rancid oils and toxins can contaminate kibble if the container is not washed
It is important to wash your kibble container between uses to prevent the contamination of fresh food with rancid oils and toxins. Kibble is sprayed with oils that break down and turn rancid once exposed to air. If the container is not washed, these oils can seep into the container's walls and contaminate the fresh kibble. Rancid fats have a distinct smell, often described as a plastic odour. Exposure to rancid fats can lead to serious health issues for your pet, including digestive problems, inflammation, hair loss, malnutrition, liver disease, and even cancer.
To prevent contamination, it is recommended to thoroughly wash the container between refills with hot, soapy water or white vinegar, and then rinse and dry completely before refilling. This ensures that any residual oils or toxins are removed. It is also suggested to keep the kibble in its original bag and then place the entire bag into the container. The bag is designed to keep the food fresh and prevent fats from leaching into the container. Additionally, the bag contains important information, such as UPC codes, ingredients, and expiration dates, which may be needed in case of a recall.
To further extend the shelf life of kibble, it is important to store it properly. Kibble should be kept in a cool, dry place, with temperatures below 80 degrees Fahrenheit. Moisture and high temperatures can lead to mould and speed up the degradation process, causing a loss of nutrients. Opened kibble should be used within one month, as the exposure to air and oxygen triggers the oxidation process, reducing the nutritional value and increasing the chances of contamination.
By following these steps—washing the container between uses, storing the kibble in its original bag inside the container, and maintaining proper storage conditions—you can help ensure that your pet's kibble remains fresh and uncontaminated, thus promoting their overall health and well-being.

Kibble should be stored in a cool, dry place
It is important to store kibble properly to maintain its freshness and nutritional value. Kibble should be kept in its original bag, which is designed to keep the food fresh for long periods of time. The bag should be sealed tightly to minimise exposure to air, moisture and contaminants.
If using a storage container, it is recommended to place the entire bag of kibble into the container, rather than pouring the kibble directly into it. This helps prevent the kibble from becoming contaminated with rancid oils and fats, which can seep into the container's walls and affect the quality of the food. The container should be made of food-grade, airtight material, such as plastic or stainless steel, to protect the kibble from moisture and contaminants.
It is important to wash and dry the storage container thoroughly between refills to remove any residual fats, oils or crumbs that could affect the freshness of the kibble. Additionally, it is recommended to choose smaller bags of kibble that can be used up within a shorter period of time, as the longer a bag of kibble sits open, the more nutrients it loses and the higher the chances of contamination.

Opened kibble should be consumed within one month
The fats in kibble can quickly turn rancid when exposed to air, and this can contaminate the rest of the food in the bag. Rancid fats have a distinct smell, often described as a plastic odour. The oxidation process also causes the nutrients in the food to break down over time, reducing its nutritional value.
To prolong the life of opened kibble, it is recommended to store it in an airtight container. Plastic containers are commonly used, but they should be food-grade and washed thoroughly between refills to prevent contamination from residual oils and toxins. Plastic containers can also leach harmful chemicals into the kibble, so it is recommended to keep the kibble in its original bag and place the bag inside the container.
By following these storage practices and consuming the kibble within one month of opening, you can help maintain the food's freshness and nutritional value while reducing the risk of any health issues for your pet.

Keep kibble in its original bag inside the container
While it is convenient to tear open a bag of kibble and pour it into a plastic food bin, it may not be the healthiest way to store your pet's food. Pet food bags are designed to keep the food fresh for long periods of time. Once the bag is opened, the fats in the kibble come in contact with air and begin to oxidize and go rancid.
The best way to store kibble is to keep it in its original bag and then place the entire bag into an airtight container. This is because the fats from the kibble can seep into the plastic container's walls and contaminate the kibble as it turns rancid. Every time you change to a new kibble bag, thoroughly wash and dry the storage container in case there is any fat residue left on the walls.
The kibble bag also has the manufacturer's information, such as UPC codes, barcodes, ingredients, etc., that you will need if there is a recall of any kind. You can tape this information to the outside of the container and remember to change it when you open a new bag of kibble.
It is also important to note that the expiration date on the kibble bag only counts toward a sealed and intact bag. Once the bag is opened, the expiration date is no longer accurate. As soon as you open the bag, air and oxygen hit the kibble and the oxidation process begins. The kibble is then safe for about 30 to 45 days.
