According to Reuters report on July 24th local time, a roundworm outbreak in the United States is affecting nine states. Michigan has been the most severely affected state, with over 8,100 confirmed cases.
Although the Centers for Disease Control and Prevention issued a health warning regarding cyclosporiasis on July 14, two weeks prior to Michigan reporting an exceptionally large outbreak of this parasitic disease, the state’s health department now lacks the resources to handle the growing number of cases due to federal government cuts in funding, delayed information from federal agencies, and limited communication channels.
According to health officials in Michigan and local authorities, state and county health departments are currently only able to temporarily assign personnel and recruit volunteers in order to try to identify potential sources of infection beyond packaged lettuce during this outbreak.
The report indicates that Michigan's current difficult situation in epidemic prevention clearly shows that without the support of federal resources during past public health emergencies, it will be very difficult for states to prevent the rapid spread of foodborne infectious diseases in advance.
In 2025, after the Trump administration canceled approximately $12 billion in special pandemic subsidies for states, Michigan reduced the number of dedicated infectious disease workers by 23, and the total number of county-level health care positions was cut by 123.
Michigan's Chief Medical Officer, Bagdasariyan, said: "We had to transfer dozens of staff from areas such as hepatitis C prevention and control, and gun violence prevention internships to support the epidemic prevention efforts."
Several former CDC officials and food safety experts stated that the cuts to federal agencies have significantly increased the difficulty of handling the pandemic. The Trump administration's decision to cut the budget of the U.S. Agency for International Development by $40 million has directly eliminated a special fund that was originally intended to support the CDC’s parasitology laboratories. Former senior CDC officials added that the large number of staff who left the agency last year and the subsequent streamlining of positions have also severely weakened the agency's ability to handle public health emergencies.
The US Food and Drug Administration stated that it is working in collaboration with the U.S. Centers for Disease Control and Prevention and public health departments in several states to investigate infections related to lettuce imported from Mexico. Previous investigations have shown that infected cases were found in Indiana, Kentucky, Michigan, Ohio, and West Virginia. Recent investigations have revealed that the number of affected states has increased to nine, with four new states being Illinois, Kansas, Oklahoma, and Pennsylvania.
Circulatezoonosis is an intestinal infection disease caused by various tiny Circulatezoa parasites, which can be contracted through contaminated food or water. Infected individuals may be asymptomatic or may experience symptoms such as watery diarrhea, frequent bowel movements, stomach pain, and nausea. If not treated promptly, the condition can last from several days to months and may recur. Generally, this disease is not life-threatening.
