Is RTFN recognized in the legal system

The Constitution of de the United States of America does not explicitly guarantee the right to adequate food.

The United States of America have signed the International Covenant on Economic, Social and Cultural Rights in 1977 but has not yet become a State party.

U.S. Deputy Representative to the UN Economic and Social Council, Terri Robl, explanation of position on right to food, 12-03-2014:

“Overall, we view the right to food as a desirable policy goal; it is our objective to achieve a world where everyone has adequate access to food. We do not, however, treat the right to food as an enforceable obligation.”
