If you make software, and your customers lose data, time, or money because you sold them buggy software due to lack of testing, you'll probably be OK. You can iterate quickly and break things regularly as you improve the product, and your customers will put up with it.
But if you make food, and your customers get poisoned because you sold them poison due to lack of testing, you're going to get in trouble. Federal and state government agencies will want to have a serious chat with you and possibly will shut you down. You cannot iterate quickly and break things regularly to improve a food product; you cannot experiment with the health of your customers.
If poisoning from Soylent bars was due to lack of careful testing prior to releasing the bars to market, shame on the company.
