The startup trying to usher in the future of food has upset quite a few stomachs.

Soylent, the Silicon Valley meal replacement startup, has recalled a newly launched product due to dozens of reports from customers suffering from "intense" and "violent" bouts of emesis and diarrhea.

In a blog post, Soylent announced it has halted all sales of its Soylent Bar, a 250-calorie snack bar made with soy protein and algae flour, in response to reports of its customers getting sick after eating the product. The Soylent Bar was released in August and started shipping to customers in September. Customers started reporting negative experiences during the first week of September. The company also advises customers to throw away any remaining Food Bars.

"It has recently come to our attention that a small number of our customers have experienced gastrointestinal issues after consuming Soylent Bars," Soylent writes on its blog. "As a precautionary measure, we are halting all Soylent Bar purchases and shipments and are advising our customers to discard any remaining bars in their possession."

Soylent, in the blog post, explains how it is taking the complaints "extremely seriously" and has "no greater priority than the quality and safety of our products." The company, founded by Rob Rhinehart, says it has started investigating to pinpoint the exact cause of the violent reactions some people have experienced after eating the bar.

"So far we have not yet identified one [cause] and this issue does not appear to affect our other drinks and powder," writes Soylent.

Soylent has not responded to requests for comment.

The company says it will refund customers who bought the bar.

On Soylent's user forum, a customer who goes by the handle is "jteach," described his experience from three weeks ago:

"Last Friday, I ate one for breakfast and about an hour later began to feel nauseous. I had to run to the bathroom to vomit and then vomited once more and had awful diarrhea. I also assumed that it was a virus. This morning, I had about 1/3 of a bar and had an even more violent reaction. I vomited a total of seven times and had several runs of the runs."

The food bar's ingredients are not allergen-free, not organic, not gluten-free and does contain soy. The list of full ingredients is rather lengthy and contains genetically-modified organisms. It's main ingredients include: Soy Protein Isolate, Corn Syrup, Oat Flour, Canola Oil, Clycerine, Whole Algae Flour, Isomaltulose, Isomaltooligosaccharide Fiber, Oatmeal.

If you come across a Soylent Bar, the company suggests not to eat it. Stay tuned for updates.
