Lynne R. Ostfeld has an interest in agricultural work through both participation with family members in the management of several family farms, as well as representing clients regarding contracts and contract law, export/import issues, customs law, and distribution networks. She has a satellite office in the farming community in Peoria Co., Illinois.

She was Adjunct Professor of international agri-business law at The John Marshall Law School, and is an active member of The Chicago Farmers, as well as of the agricultural law committees of the ABA and ISBA. She is also a member of the American Agricultural Law Association.

In September 2001, she spoke to a group of French farmer representatives (Euralis) in Chicago about issues of concern for the American farmer, whether it be the continuation of the family farm, the dilemma of choosing between GMO and non GMO seeds, landlord-tenant lease issues in the U. S., and environmental issues. In June 2002, she helped the French Economic Mission in Chicago and The Chicago Farmers organize a tour and discussion for French officials interested in agricultural issues. The topics included the 2002 Farm Bill, alternative farming, and GMO crops, among other things. In 2004, at the request of the French Consulate and Embassy, she organized a meeting for the French Minister of Agriculture, Hervé Gaymard, to discuss French agriculture policy, with the French Ambassador to the U.S., David Levitte, also in attendance. In 2007, she spoke at Les Entretiens de Summit (Paris, France) about exporting food from France into the United States. In 2008 and 2014 she spoke at the Illinois State Bar Association Agriculture Law Seminar on food safety issues and at the 2022 Bock Symposium on Contracts and International Supply Chains in a Time of Uncertainty.
