The shuttering of three projects is expected to hinder vital research at a time when consumers are increasingly worried about the safety of the food supply.

The Trump administration is shuttering research projects key to the federal government’s fight against cyclospora, the foodborne parasite sickening thousands of Americans this summer.

Two of the three projects that represent nearly all of the Agriculture Department’s study of the parasite were defunded by Congress earlier this year, according to the agency. The third is slated to move from Maryland to Iowa this fall as part of a sweeping USDA reorganization. Even though that project still has money, every scientist working on the parasite has declined to relocate, according to three people familiar with the plans and documents shared with POLITICO, granted anonymity to discuss personnel issues.

The hollowing-out of all three projects, which has not been previously reported, is expected to hinder vital food safety research at a time when Americans are increasingly worried that they can’t trust the food supply.
