Hershey and Mars have reportedly been hit with lawsuits linked to their alleged involvement in a price-fixing scheme in the US.

Three lawsuits have been served against Hershey, Mars and other confectionery makers, said the Associated Press on Saturday (5 January).

The legal action comes just weeks after the US Justice Department began an inquiry into how chocolate makers in the country set prices.

Last month, Canada's Competition Bureau served warrants on several major manufacturers, including Hershey and Mars, requiring them to surrender information on their pricing policies.

The lawsuits were filed in Harrisburg, Pennsylvania and Newark, New Jersey, AP said.

Officials at Hershey and Mars could not be reached for immediate comment.
