How Can You Tell if Your Chia Seeds Are No Longer Safe to Eat?

Chia seeds are resilient; they can last pretty long. It is because of the high amount of antioxidants present in them. But how can you be sure if they are still good to use? You can tell when your chia seeds start losing their crunchiness. If chia seeds become slimy, it means they have gone bad, and you should throw them away.

Let’s go over a few other ways to tell if your chia seeds are bad:

Change in Taste

The taste of the chia seeds should be mild, almost nutty. If you feel they taste bitter or have an off flavor, it’s time to eliminate them.


Usually, people store their chia seeds in opaque containers. It can make it hard to spot an infestation. The ideal way is to check for small bugs around the container. You must check the area for any droppings as well.

The Seeds are Rancid

Rancidity is when the oil goes bad. Rancid chia seeds will have a funny smell and taste. It happens when the seeds are exposed to oxygen, light, and heat for too long.

There is Mold

It is something you need to look out for. If you spot mold growing on the chia seeds, discard them immediately. Mold can cause serious health issues if ingested.

Best Ways to Store Chia Seeds

For optimal chia seed storage, ensure the container is airtight. Mason jars are great for this. It will prevent any moisture from entering. When you have to use dried chia seeds, pour them out instead of scooping them out of the container. It will reduce the risk of the remaining chia seeds getting exposed to moisture.

Keep the container in a cool, shaded place away from direct sunlight or heat sources. It is because heat and light can accelerate the process of spoilage.

Refrigeration is another option; it can keep your chia seeds fresh for up to four years.

You can also freeze the chia seeds if you want them to last even longer. Just ensure you store them in a Ziploc bag or airtight box. Then, when you want to use them, you only have to scoop out the amount you need and store the rest back in the freezer.

It’s important to remember that opening the original packaging doesn’t mean your chia seeds will go bad immediately.

Can You Consume Expired Chia Seeds?

Another important question besides “How long do chia seeds last?” is whether you can consume them after the expiration date. The answer is: Yes!

You can consume expired chia seeds. It is because the printed date doesn’t correspond to the expiration date. Plus, if there are no signs of spoilage, it is safe to consume them.

However, since the nutritional value of the chia seeds will have degraded with time, it is best to replace them before they go bad.
