It never seems to be a Listeria recall without having an expansion of that recall. This occurs when companies realize that they did not have real control of the organism, whether that is a contaminate within the processing environment or within purchased raw materials. Since sunflower seeds are roasted and de-hulled, it would lead one to believe it was post roasting contamination.
The process of making sunflower seed is similar to other processing of nut. For a nice review of the process, you can visit 'How Products are Made. Here are the highlights from that review"
Sunflower seed production begins in early spring when the fields are prepared and the seeds are planted.
- Sunflowers are ready to harvest when the black part of their heads turns brown. In the United States this is generally in late September or October. A special device collects the sunflower heads
- The seeds are rapidly dried to under 10% moisture content and then stored in grain elevators.
- At the processing plant, they are emptied onto wire screens and shaken to remove dirt, inspected, and further cleaned.
- The seeds are then passed on to sizing screens which separate them by size.
- Large sized seeds go to snack food sunflower seeds are transferred through large ovens to dry roasted, reducing the moisture level in the seed further. The medium sized seeds are first sent through de-hulling machines which remove their shells. They are then roasted in oil
- The seeds are then flavored as desired. This can be done by an enrobing process - running the warm seeds from the roasters into a large, rotating container where combined with oil the flavoring ingredients.
- The seeds are then packaged with a focus on reducing oxidation that would promote rancidity.
