Kroger customers may be in for more spam -- but not the kind found on grocery store shelves.
The grocery chain said a database with customer names and e-mails that is operated by a third-party was breached earlier this week.
The database contains the names and email addresses of customers who have provided the information to Kroger, the company said in an e-mail to customers.
Kroger said no other personal information or credit card information was compromised.
But the company said customers may notice an increase in spam email.
Kroger said the security breach affects customers in regions across the country but not all customers.
