Meal replacement sludge company Soylent prides itself on the artificiality of its ingredients — no milk products or perishable components to worry about while you free yourself from the tyranny of actual food. That's why Soylent, which has struggled to gain confidence from consumers after reports last year that some were sickened by its products, is issuing a voluntary recall of its Soylent 1.8 powder over the potential presence of milk, which is not listed as an ingredient in Soylent. According to the FDA announcement, no illnesses have been reported in connection with the problem.

"This voluntary recall is immediately being initiated after it was discovered that the milk-containing product was handled adjacent to the production lines for Soylent 1.8 powder," the company writes. "Subsequent investigation indicated that the potential cross-contact was caused by a temporary breakdown in our 3rd party manufacturer’s production and packaging processes."

In addition to upsetting the stomachs of lactose intolerant customers, the presence of undeclared milk product in Soylent could also upset the sensibilities of vegan consumers.

In October 2016, some Soylent customers posted horror stories detailing the diarrhetic effects of their Soylent bars. After suspending sales of the bars, which also reportedly caused extreme nausea and vomiting, Soylent blamed its algal flour supplier. At around the same time, the company also recalled its central powder product after similar reports. The flour supplier, in turn, denied its product, made from lab-grown algae, was to blame.

As Soylent consumers on their dedicated Reddit page have been through the ringer before, this time, many expressed confidence in the fact that the company issued the current recall. "Mixed feelings about this," writes one user. "Doesn't look good on their manufacturing quality. But at least they didn't try to hide a mistake."
