Protecting Grain Markets from Allergen Risks

Allergenic crops of concern include: mustard, soy, and buckwheat

Even small amounts of allergenic crops mixed with cereals can cause major problems, including market rejections.  As this is a tough crop year for wheat, oats, or barley farmers already, maintaining Canada’s reputation for clean and safe grain is essential for both domestic use and international trade. 

Allergenic crops such as mustard, soy, and buckwheat are of particular concern. In export markets, these grains are classified as allergens. If trace amounts are found in wheat, oats, or barley, shipments can face strict penalties. This is because many countries enforce tough regulations on food allergens to protect consumers. 

Strategies to Minimize Allergen Risk in Storage and Transport 

Effective allergen control begins with meticulous management of storage and transportation. The following strategies can help safeguard your cereals and protect consumers: 

1. Rigorous Equipment Cleaning 
After harvesting allergenic crops, allocate additional time to thoroughly clean combines, grain carts, trucks, and storage bins before using them for wheat, barley, or oats. 

2. Segregation During Storage and Transport  

• Store allergenic and non-allergenic grains in separate bins to prevent cross-contamination.  

• Ensure trucks are properly cleaned before loading cereals, especially if they previously carried allergenic materials. 

3. Documentation and Communication  

• Keep detailed records of crop rotations, storage bin usage, and equipment cleaning protocols where possible.  

• Proactively communicate your crop rotation and storage practices with grain buyers to support transparency and traceability. 

The consequences of contamination are serious. Shipments may be downgraded, rejected at ports, or even banned from entering key markets. Beyond the immediate financial loss – which in a tough year will make it tougher-- repeated issues could damage Canada’s long-standing reputation as a reliable supplier of clean grain. 

One allergen, buckwheat, is especially dangerous because it can cause severe allergic reactions in consumers. This highlights why strict separation, careful cleaning, and proper handling are so important throughout the supply chain.  

Farmers, handlers, and exporters must work together to reduce risks and meet international quality standards. 

Protecting Canada’s grain industry requires ongoing vigilance. Training for producers and handlers, investment in cleaning systems, and strong communication with global buyers all help ensure confidence in Canadian exports. The focus is not only on selling grain but also on safeguarding health and maintaining market opportunities.
