Seattle Times on a medical mystery

Via the Seattle Times, this look at a pretty horrific recall from this summer: 

Kirsten Paulsen began 2022 wanting to eat healthier and incorporate more vegetables into her diet. She found Daily Harvest, a food delivery company that touts easy to prep, plant-based meals, and signed up for regular shipments of smoothies, vegetable bowls and vegan ingredients to add to other dishes.

In one shipment, the Bellevue resident received a bag of French lentil and leek crumbles, for customers to add protein to a lasagna or an empanada. She prepared them according to the company’s instructions and added them to a meal. Within a day, she recalled, she was sweating profusely, dry heaving on the floor, in pain she equated to worse than giving birth to her son.

Her husband took her to an emergency room, where she was told she had heightened levels of bilirubin that could indicate potential issues with her liver or bile duct, and she was severely dehydrated. The doctors weren’t sure what caused the symptoms...

...In July, Daily Harvest posted on its website that it had identified tara flour, a plant-based ingredient that’s high in protein, as the cause. The company launched an investigation, founder and CEO Rachel Drori wrote, and worked closely with the FDA, the Centers for Disease Control and Prevention, “as well as top doctors, microbiologists, toxicologists and three independent labs” to determine what caused the adverse effects. The crumbles were the first and only time tara flour was used by Daily Harvest, which has more than 140 items, Drori wrote.

Tara flour comes from the tara tree (which comes from South America). Seems to me that there's probably some kind of hepatotoxin that wasn't well-known that will ultimately be found, but we shall see...
