A class action lawsuit says Safeway failed to notify its regular customers about a Salmonella recall, even though it had the tools to do so through its Safeway Club Card program.

But Safeway says it’s not always possible to reach shoppers via its loyalty program, although it says it attempts to do so in other ways.

Filing the complaint in California are two Safeway shoppers, Dee Hensley-Maclean of Montana and Jennifer Rosen of San Francisco, with the assistance of the Center for Science in the Public Interest (CSPI).

Hensley-Maclean said she bought peanut butter crackers and Nutter Butter sandwich cookies that had been recalled because of Salmonella contamination. Rosen said she bought Salmonella-contaminated eggs.
