Food safety is now front and center in the public's mind following the recent peanut scare.

Clark is a Costco Wholesale member and was recently alerted by the warehouse club that a box of Clif Bars he purchased had been recalled. Some people say there's a creep-out factor to Costco knowing everything that every member ever bought, but in this case, it was a very good thing.

Yet what if you bought a recalled product anonymously at a supermarket?

Grocery retailer Kroger is experimenting with a checkout-based solution at its Ralphs and Food for Less locations across the country.

If a recalled item is scanned, the register will actually block the sale and issue an audible warning, according to The Los Angeles Times.

There is some pushback in the industry over this issue. Retailers see it as just one more thing to deal with in their chain of responsibility.

But you have a right to have a safe food supply, especially if you have children. Clark hopes the sheer pressure of market share will prompt other chains to follow Kroger's lead.
