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.
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.
