Can you get sick from eating expired edibles?

In this brief guide, we are going to answer the question “can you get sick from eating expired edibles ”. Moreover, we are going to discuss whether or not edibles are safe to consume past the “best before” date and the tips to properly store edibles.

Can you get sick from eating expired edibles?

Yes, you can get sick from eating expired edibles. Cannabis edibles are related to several food outbreaks due to the contamination of pathogenic bacteria, such as E.coli and Cl.botulinum, and molds, which may occur during production, handling and storage of these products (1).

There were reports of edibles containing high levels of pesticides residues, yeasts and bacteria infections by Shigella and Salmonella (2).

However, not only eating expired edibles result in illness. The over ingestion of cannabis edibles and edibles containing elevated doses of THC can result in symptoms of intoxication, undesirable cardiovascular and gastrointestinal symptoms.

Therefore, because there is no regulatory inspection or regulations regarding cannabis edibles, consuming edibles is a risk in itself, as you don´t know how they were produced and what they contain.

What factors determine the shelf life of edibles?  

The following factors may affect the shelf life of edibles (2,3,4):

  • The nature of the ingredients: some products, such as ready foods, has a high water activity (which is the free water in the food available for the growth of microorganisms and enzymatic reactions) and are more susceptible of spoilage
  • The initial microbial load: the initial contamination of ingredients are determinant for the reduction or improvement of the shelf life. Cannabis plants may carry microorganisms, as well as the other ingredients
  • The production process: heat treatments usually improve shelf life, as they are able to reduce the microbial load of the food
  • The storage conditions: Storing edibles in the presence of heat, sunlight and moisture may decrease the shelf life, as these factors increase the degradation rate of food
  • The packaging material: Packaging is used to protect food from environmental factors and from microorganisms. Good packaging material may increase the shelf life of edibles
  • Food handling: Improper handling and unsafe hygienic practices during production and storage lead to food contamination and increase the risk of foodborne illnesses  

Do edibles expire faster than cannabis oil?

Yes, cannabis edibles expire faster than cannabis oils. This happens because food is generally processed by heat treatments, dehydration and others, which result in degradation of the cannabinoids, the active chemical compound of cannabis. 

Handling, transporting, processing and cooking can affect this compound, leading to the formation of harmful degradation products. The long storage can also result in the generation of undesirable compounds (3).

The mixture of cannabinoids with other ingredients in the food matrix can also result in their degradation, especially when considering acidic foods.

How to properly store edibles?

The correct way to store edibles depends on the nature of the product. As mentioned earlier in this article, there are many factors which determine the shelf life of cannabis edibles. 

As a general rule, cannabis edibles should be kept away from UV light and heat, as the degradation of the cannabinoid oils degrade faster under these conditions (2,3). 

For instance, bakery products should be stored in the pantry for up to 2 days or in the freezer for 3 months (5). Candies and gummies should be stored at room temperature and free from moisture. Chocolate should be kept in a cool environment away from light, moisture and oxygen.

Ready meals should be refrigerated and consumed within 2 days or frozen for 2-3 months. 

How to know if edibles are spoiled?

To know if edibles are spoiled, you should carefully observe the texture and smell, the appearance and be able to notice any alterations or possible signs of spoilage, such as (6): 

  • The generation of gas (which can be noticed by the bloating of packaging or container) 
  • Generation of off-odors, such as sour, putrid or rancid
  • Formation of a slimy texture, which may indicate bacteria or yeasts
  • The growth of fuzzy colonies or colored spots can be signs of mold or yeast growth
  • Changes in the color is also a possible sign of spoilage. Long storage leads to discoloration, due to oxidation reactions
