The U.S. government is recommending consumers to avoid eating peanut butter products such as cookies, crackers, cereal, candy and ice cream on risk they may be contaminated with salmonella.

The Centers for Disease Control and Prevention has reported six deaths in connection with the salmonella outbreak and 474 people infected in 43 states. Consequently an investigation is been made.

Some companies including Kellog and General Mills have voluntarily recalled some of its products made with peanut paste or butter from a plant from Peanut Corp. of America where the salmonella was found and began to spread.

Major-labeled peanut butter producers like Peter Pan, Jif and Smuckers have not been linked to the outbreak.
