I agree that it makes sense to punish the poisoners. I am confused about why, presumably, not-poisoners are murdering other not-poisoners.

They keep saying it's safe. I think nobody's actually died, maybe that's all they mean by that.

There's confusion about whether the food is in fact poisoned?

Of course it is, it just won't outright kill you.

What does it do, then?

It's unclean. Some people are refusing to eat rather than eat the poisoned food and other people are eating it but getting sick. Some people seem okay but even they don't like it.

Do you know what makes some people get sick while others don't?

No.

Do you know what specifically was done to the food?

I told you, the reds are touching it.

And are they putting foreign substances in it? Failing to take some steps that are ordinarily taken in food preservation?

...maybe? I don't know. They're touching it.

I am trying to figure out the mechanism by which their touching it leads to people getting sick.

I'm surprised more people aren't, I keep expecting to.

Can you put me in touch with someone with relevant medical expertise, maybe?

I'm not supposed to have this thing.

People are dying. 

So will I, I'm really not supposed to have it.

...I am confused about how that would cause you to die. 

The enemy's jamming the radio and if they notice I unjammed it to talk to aliens they'll hit us harder than they have been, official word is let them jam, so it's sorta kinda treason.

Okay. What percentage of people who eat the poisoned food have gotten sick? How sick have they gotten, what kinds of things are they experiencing?

I don't know a percentage. Maybe ten percent. They're throwing up or shaky or weepy or itchy.

And it's not known what's causing this?

I told you they're letting reds touch the food! They're picking it and milling it and packing it and putting it on trucks!

- wait, is the claim that even if they don't put any substances in the food, or change food preparation procedures in some way, people will get sick as a consequence of their having touched it at all?
