No financial or clinical information was affected in January when "certain patients' names and email addresses were improperly shared" between Kroger's postal prescription service and its grocery business, the company said March 10.
The first and last names of patients who created accounts between July 2014 and Jan. 13, 2023, as well as their email addresses were used to create a Kroger grocery account.
"Kroger has not received any indication that the information was misused because of this incident," the company said. "However, as a general best practice, customers are encouraged to remain vigilant and monitor their accounts for any suspicious activity, and to report any suspected incidents of fraud to their financial institutions."
Kroger said it became aware of the issue Jan. 10 and has since updated the mail-order pharmacy's website to address the problem.
