The chia seed sprout contamination occurred prior to them being dried and ground for powder. Chia sprouts harbor the seeds, which are removed from the sprout and sold in seed form or ground into chia powder. The warmth and moisture of the sprouting process allows any microbes that may be on the seeds to grow which puts sprouts so sprouts are already considered high risk. During the chia seed sprouting process the salmonella microbes remained when the sprouts were dried and ground, causing them to become contaminated. The CDC has recommended that consumers not eat any recalled chia products.

The FDA is currently investigating Evergreen Fresh Sprouts, LLC of Idaho, which it believes is the source of the E. coli outbreak. During its investigation the FDA discovered that two employees scooped mung bean sprouts with scratched and chipped tennis rackets that had frayed plastic and sponge-type handles from the harvester. The employees then used them to harvest alfalfa a day later. Another employ was found to have used a pitch with corroded metal and rough welds to move mung bean sprouts into plastic tubs.

Other states where chia seed products were linked to an outbreak of salmonella infections are Colorado, New York and Washington and Arizona. The CDC recommends that anyone who has purchased any of the recalled items to either throw them out or return the to the retailer where they were purchased.
