Washington — Congress agreed this week to continue counting the tomato sauce on a slice of pizza as a serving of vegetables for federally-sponsored school lunches.

In doing so, it sided with one of biggest makers of frozen pizza for school lunches the Schwan Food Co. of Marshall, Minn., a frozen pizza giant with more than $3 billion a year in annual sales. The privately held company was at the heart of the lobbying battle in Washington over pizza and convinced several members of Minnesota’s congressional delegation to follow its lead.

Democratic U.S. Rep. Keith Ellison and Republican U.S. Rep. Erik Paulsen were the only Minnesota members of Congress to vote against the bills.

Schwan Food pizza brands include Red Baron, Freschetta and Tony’s Pizza. Besides the products it sells to consumers, Schwan’s does a big business selling frozen pizza to the federally-subsidized school lunch program.

A recent press release from the company boasts that it has a 70 percent market share in the pizza category of the $9.5 billion school food service industry.

So when the U.S. Department of Agriculture proposed new, stricter nutritional standards for school lunches earlier this year, it set off a massive lobbying campaign by Schwan and companies such as food giant ConAgra.
