This sort of thing is premature fear mongering to sell clicks.

A useful summary:

- Some people have gotten sick. There is no indication as to why or how. Likely possibilities include:

  - circumstantial/no causation

  - contamination of the batch (biological or chemical)

  - allergic reaction to an ingredient (happening 'now' could be a result of accumulation) 

- This was all from the same batch (per current evidence)

- This batch has been recalled and they are trying to figure out what went wrong. (the thing we expect any food manufacturer to do when something like this happens)

I expect Soylent is an interesting exercise in people finding out they have allergies they did not know about, but I am going to wait and see before I hunting for spare pitchforks.
