HOW TO TELL THE DIFFERENCE BETWEEN TYPES OF CANARYSEED
Without looking under a microscope, it's almost impossible to tell the difference between the traditional Phalaris canariensis (alpiste, canary grass seed) and canaryseed without silica fibers. In fact a lot of people—including people who sell canaryseed—still don’t know there’s a difference at all, much less the risks that traditional varieties could pose for people who consume it.
Most canaryseed grown and sold today is still the traditional kind, with the potentially dangerous silica fibers on the hull, so it's important to carefully choose which brand of canaryseed to buy.
To make sure you're buying the right kind, look for the Silica Fiber Free™ seal on the package. That special seal, issued by the Canaryseed Association of North America (CANA), can only be used on packaging for varieties of canaryseed lacking silica fibers that are sold by reputable companies. If you're shopping for canaryseed and you're not 100% confident the canaryseed is the right kind, find a different supplier who knows the difference and can guarantee what you’re buying.
At Pureza we know that the canaryseed we sell is only those lacking silica fibers because we contract directly with farmers who plant and harvest it for us. On the Pureza package, we use the Silica Fiber Free™ canaryseed seal so you can immediately see that you're buying the right kind.
