Days after the snack food company Mondelez International recalled some of its Ritz cracker products after a whey powder supplier identified a potential salmonella risk, the company announced that two people had fallen ill after eating the crackers in question.

Kimberly Fontes, a Mondelez spokeswoman, said on Tuesday that the company was in contact with both of the people, who reported their illnesses after the recall was announced on Saturday.

Mondelez was one of several food companies to issue recalls based on potential contamination from whey powder provided by Associated Milk Producers Inc., a dairy company based in New Ulm, Minn.

On Monday, Flowers Foods recalled some of its swiss rolls and bread products, and on Tuesday, Pepperidge Farm announced a recall of several of its Goldfish cracker varieties in the United States. The companies were not aware of any related illnesses as of Tuesday, according to the United States Food and Drug Administration.
