CHICAGO (STNG) - A tapeworm almost 10-feet long passed through a man after he ate at a  high-end seafood restaurant, according to a lawsuit filed Monday.

Anthony Franz is suing the parent company of Shaw’s Crab House for causing him to become “violently ill” after eating allegedly undercooked salmon at the River North neighborhood restaurant.

The suit, filed Monday in Cook County Circuit Court, claims Franz ate periodically at Shaw’s at 21 E. Hubbard St. between May and August 2006.

For several days, Franz became violently ill and eventually passed a nine-foot long tapeworm, the suit said. (File photo)

A suburban doctor he visited in late August said he got the tapeworm from eating undercooked fish.

Franz started eating at the restaurant as part of a healthier diet, the suit said.

He claims in the two-count suit that the restaurant failed to supervise employees in safe food handling and allowed customers to eat food that was not safe to consume.

The suit, which seeks in excess of $50,000 in damages, is against Just B. Claws, Inc.
