Pepperidge Farm is voluntarily recalling four varieties of Goldfish Crackers because of fears they could potentially have salmonella. The company, owned by Campbell Soup, on Monday took the action after one of its ingredient suppliers notified it that whey powder used in a seasoning may be contaminated.

‘Pepperidge Farm initiated an investigation and, out of an abundance of caution, is voluntarily recalling four varieties of Goldfish crackers,’ the company said in a statement posted to its website. The Goldfish recall covers Flavor Blasted Xtra Cheddar, Flavor Blasted Sour Cream & Onion, Goldfish Baked with Whole Grain Xtra Cheddar and Goldfish Mix Xtra Cheddar + Pretzel.
