That's hardly amazing; I've known since I was a child that the main source of salmonella was eggs and possibly raw chicken. In fact, I'd have been hard-pressed to name another place you could get it.

If you look at the data [0] on food recalls and safety warnings in the United States, you'll see that the large majority of food-borne salmonella occurs not in meat or eggs but in fruits and vegetables, particularly in ground-hugging varieties like peanuts, lettuces, peppers, and bean sprouts.

This is almost always either because (a) the vegetables are fertilized with manure (organic vegetables, in particular, carry a higher risk of fecal contamination and associated diseases) or because (b) they're processed and packed in contaminated facilities. It is a self-fulfilling irony of the regulatory regime that vegetable-processing plants, which are more likely to be contaminated, are subject to less stringent safety standards than their meat- and poultry-processing counterparts.

Is possible/likely that that is (partially-) chicken manure?

If so, reducing/eradicating endemic chicken salmonella might also remove it from the manure.

It's a somewhat common concern with pet reptiles.

I knew a family who had a child very seriously ill with salmonella thanks to a pet turtle. The child survived, the turtle moved on.

Iguanas.

There was a salmonella outbreak linked to peanut butter just months ago. All of the peanut butter at Trader Joe's was recalled.

That's incorrect. Only specific variants of their peanut and almond butters were recalled. That particular manufacturer also provided their product to many other companies.

Not to state the obvious, but ...salmon?

The bacteria is named after Dr. Salmon, not related to the fish.

True, but you still can get it from salmon (http://www.huffingtonpost.com/2012/10/02/smoked-salmon-salmo...).
