Daily Harvest identifies likely culprit behind hundreds of illnesses

Daily Harvest says investigators believe one ingredient is to blame for gastrointestinal issues that sickened hundreds of people and prompted the recall of the food company's French Lentil + Leek Crumbles in June. 

"At this time, we have identified tara flour as the cause of the issue," Rachel Drori, founder and CEO of the vegan meal-kit delivery service, said in a blog post. 

Made from the seeds of tara trees grown in Peru, tara flour surfaced as the likely cause after weeks of investigation by microbiologists, toxicologists and three labs, Drori said. Work continues with the unidentified flour producer and the Food and Drug Administration to figure out what specifically made customers ill, she added.
