Salmonella contamination has been tracked to the machine that made the products.
The problem was first noted in the Trader Joe's Valencia Creamy Salted Peanut Butter brand and then expanded to all kinds of products like cookies, crackers and sauces made with the contaminated peanut butter.
No one has gotten sick from cookies and other snacks made with the peanut butter, but those products are also being pulled by Giant Foods, Stop N Shop, Whole Foods and Newman's Own Organics.
The Archer Farms brand of peanut butter sold at Target is also on the list.
Federal investigators traced the contamination back to the processing plant in New Mexico, which issued this statement:
"...nothing is more important to us than the health and safety of our customers....as a precautionary step, we have decided to voluntarily recall our almond butter, peanut butter and cashew butters, tahini and roasted blanched products.."
The Centers for Disease Control has so far confirmed 30 cases of salmonella poisoning in 19 states.
"Classic salmonella symptoms, nausea, vomiting, diarrhea, abdominal cramps. and these usually are self-limited, they go away anywhere between 4-7 days, but the symptoms can be worse," says Tanya Benenson, M.D.
Four people have had to be hospitalized, most of them children under 10.
