"Soto’s team analyzed the retention of CWD and other infectious prion proteins and their infectivity in wheat grass roots and leaves that had been incubated with prion-contaminated material. They discovered that even highly diluted amounts of the material can bind to the roots and leaves. From there, they fed the wheat grass to hamsters, which became infected with the disease."

If you read the article instead of the press release, you'll see that Soto's group showed that wheatgrass can be contaminated by hamster prions or CWD prions, but that they only showed transmission of hamster prions to hamsters through exposure to the contaminated wheatgrass. That's not cross-species transmission.
