Here’s a look at some of this week’s product recall and safety announcements.

Mazda recalls nearly 80K vehicles to replace faulty air bags

Mazda is recalling nearly 80,000 cars and SUVs, some for a second time, to replace dangerous Takata air bag inflators.

The recall covers front passenger inflators on certain 2007 through 2009 and 2012 CX-7, CX-9 and Mazda 6 vehicles. The recalls vary by state and age of the vehicles.

Takata inflators can explode with too much force and hurl shrapnel into drivers and passengers. As many as 19 people have been killed and more than 180 hurt due to the problem.

The recall supersedes one issued in January that temporarily replaced older Takata inflators with the same parts. Ammonium nitrate used in the inflators can deteriorate over time. The company says newer inflators are safer. In the latest recall, dealers will install permanent replacement inflators that don’t use ammonium nitrate.

Lawsuit claims rodent was baked into Chick-fil-A sandwich

A woman in suburban Philadelphia is suing Chick-fil-A after she says she found a dead rodent in her sandwich.

Ellen Manfalouti filed suit in Bucks County Court, claiming that the tiny rodent was baked into the bottom bun of her chicken sandwich.

The 46-year-old tells The Philadelphia Inquirer that her co-worker picked up the sandwich at a Langhorne restaurant in November. The two started to eat when she “felt something funny” and thought the bun was burned.

Her co-worker says she knew it was a rodent because she saw the whiskers and tail. Manfalouti is seeking more than $50,000 for physical and psychological damages.

The fast-food chain says it won’t comment on litigation.

Government joins food fight over menu labeling requirements

The U.S. government has joined a food fight between New York City and a national group opposing new food labeling regulations for chain grocery and convenience stores.

The Department of Justice filed legal papers this week on behalf of the Food and Drug Administration, asking a judge to block the city from enforcing a law requiring some stores serving prepared foods to post calorie information where the foods are sold.

The National Association of Convenience Stores is challenging the rules in court, arguing that provisions of President Barack Obama’s health care bill called for national standards and that enforcement by local municipalities violates that law.
