First it was Soylent’s Food Bars that were making customers vomit, causing it to halt sales and shipments. Now, it’s the powder that is making a “handful of customers” extremely ill, prompting them to pull the product from shelves, according to a blog post on Thursday. Soylent says that “for the past several weeks, we have worked aggressively to uncover why people were having these negative experiences” and has failed to uncover any “food pathogens, toxins, or outside contamination.” Yet it has been able to isolate the problem to Powder 1.6, since customers who tried the earlier versions didn’t get sick.
Soylent says it is reformulating the bar and powder, sharing its findings with the Food and Drug Administration, and expects both products to be ready in the first quarter of 2017. So far, it hasn’t heard complaints about Soylent Drink or Coffiest.
