(CNN) - Four types of Duncan Hines cake mix have been recalled for possible salmonella contamination.
Conagra brands voluntarily issued the recall. The Food and Drug Administration says the DNA fingerprint found in the cake mix sample matched one linked to five cases of salmonella illnesses.
According to Conagra, several sick individuals told health investigators they consumed cake mix before their symptoms began. However, the company noted that some of the sick individuals could have eaten the mix raw rather than cooked.
The recalled cake mixes were distributed nationwide and to some international exporters. They are all 15.25 oz boxes of mix.
The recalled white cake mix has best if used by dates of March 7, 8, 9, 10, 12 and 13, 2019 and the UPC code 644209307500.
The recalled yellow cake mix has best if used by dates of March 9, 10, 12 and 13, 2019 and the UPC code 644209307494.
The recalled butter golden cake mix has best if used by dates of March 7, 8 and 9, 2019 and the UPC code 644209307593.
The recalled confetti cake mix has best if used by dates of March 12 and 13, 2019 and the UPC code 644209414550.
Retailers should no longer sell these recalled mixes and consumers who have recalled mixes should contact Duncan Hines or the store where the mix was purchased for a refund.
