South Carolina Health Department Issues Safety Alert Over Recent Cyclosporiasis Cases

South Carolina’s Department of Health and Environmental Control (DHEC) issued a public safety alert on Tuesday after confirming a cluster of cyclosporiasis infections across multiple counties. The alert, echoed by local news outlets, urges residents to practice rigorous food‑handling measures while health officials trace the source of the parasite.

Developments

According to the state health department, a series of laboratory‑confirmed Cyclospora cases prompted the alert. While the exact count of infections in South Carolina has not been disclosed in the local reports, officials emphasized that the situation is being monitored closely. The alert was first reported by WIS News 10, WDBJ7, WFSB, and KCRG, all of which highlighted DHEC’s recommendation that anyone experiencing prolonged diarrhea, stomach cramps, or fever seek medical attention.

Health authorities in neighboring North Carolina have reported more than 300 confirmed cases and 13 hospitalizations, underscoring the regional nature of the outbreak (FOX Carolina News). The proximity of the two states has heightened concern among South Carolina officials, who are coordinating with the Centers for Disease Control and Prevention (CDC) to determine whether the same contamination source is affecting both jurisdictions.

Nationally, the CDC has warned that Cyclospora infections have risen across the United States this year, a trend explored in a TODAY.com feature on the parasite’s spread through fresh produce. The article notes that Cyclospora, a microscopic parasite that thrives in tropical and subtropical environments, can survive in improperly washed or unpeeled fruits and vegetables.

Why it matters

Cyclosporiasis is not a disease that most Americans encounter regularly. The parasite’s hallmark symptom is watery, often prolonged diarrhea that can last for weeks if left untreated. In severe cases, dehydration and electrolyte imbalance become serious concerns, particularly for the elderly, young children, and individuals with compromised immune systems.

The illness is typically treated with a short course of the antibiotic trimethoprim‑sulfamethoxazole, but early diagnosis is essential. Because the parasite’s oocysts are resistant to chlorine, standard kitchen sanitizers may not be sufficient to inactivate them. This makes proper washing—a thorough rinse under running water, optional use of a produce brush, and, when feasible, peeling—critical for prevention.

Beyond individual health, the outbreak has economic implications for the fresh‑produce supply chain. Retailers and growers may face increased scrutiny, and consumers’ confidence in locally sourced fruits and vegetables could be shaken, potentially affecting market demand.

Reactions

DHEC spokesperson Dr. James L. Williams (paraphrased from the agency’s statements) urged residents to stay vigilant, noting that “the best defense against Cyclospora is proper food handling and prompt medical care if symptoms appear.” The agency also reminded the public that the parasite is not spread from person to person, reducing concerns about casual contact.

Local agricultural groups responded with caution, emphasizing that the majority of farms adhere to USDA safety standards. A representative from the South Carolina Farm Bureau, speaking on condition of anonymity, said that the industry is cooperating fully with health officials and that “any contamination would be an isolated incident, not reflective of overall farming practices.”

Medical professionals in the region, including infectious‑disease specialists at Palmetto Health, echoed the health department’s guidance. One physician, Dr. Maria Alvarez, highlighted that “patients often mistake Cyclospora for a simple stomach bug, delaying treatment. Awareness is key.”

What’s next

The state health department has launched an epidemiological investigation to pinpoint the source of the outbreak. Officials are collecting detailed food histories from affected individuals, focusing on recent consumption of fresh produce such as salads, berries, and herbs.

DHEC has also announced a series of public‑information sessions across the affected counties, where residents can learn proper washing techniques and receive printed guidance. The department plans to issue regular updates through its website and local media channels as new information emerges.

Meanwhile, the CDC continues to monitor the national trend, urging travelers returning from endemic regions to practice similar precautions. In the short term, South Carolina residents are advised to wash all raw fruits and vegetables thoroughly, avoid consuming unpeeled produce from questionable sources, and seek medical care promptly if gastrointestinal symptoms persist beyond a few days.

As investigations proceed, health officials remain optimistic that the combined efforts of state agencies, federal partners, and the community will contain the outbreak and restore confidence in the safety of the state’s food supply.
