WASHINGTON -(Dow Jones)- The U.S. Food and Drug Administration has asked a variety of food companies to recall more than 30 products, from vegetable dips to soups, that contain a commonly used food additive that has tested positive for salmonella.

The FDA said no injuries have been reported related to the recall. Products being recalled include pre-packaged foods made by Earth Island, tortilla soup mix made by Homemade Gourmet and chicken soup base made by Castella Imports.

The FDA said these products contain a flavor-enhancing ingredient called hydrolyzed vegetable protein, or HVP, that is used in commercially processed foods. The FDA said the HVP came from one company, Basic Food Flavors Inc. of Las Vegas.
