Response from Blue Diamond:
First, Blue Diamond only processes almonds; however, the transportation equipment used to transfer the almonds from the orchards to the processing facilities is shared with other nut growers. Many of our almond growers in our grower co-op have other tree nut orchards (separate from the almond orchards).
Let me emphasize that the harvested almonds are NOT shipped together with any other nuts; however, because the equipment is shared , it is possible that a stray walnut, pistachio or hazelnut be left behind in the dumpers.
With our tightly controlled processes, it is unlikely that something like that would get through our system and into our finished/packaged products, but in the event it does, we need to inform our consumers of the possibility with that statement on our packages.
Other tree nuts would include walnuts, pistachios and hazelnuts.
***I replied to ask if they sell them in the shell. Would others agree this would be least likely to be contaminated? DS12 is not supposed to be allergic to any treenuts, but he had a low hazelnut number years ago so I'd rather be sure we're just getting almonds.
