Health authorities in the UK have confirmed a rise in cyclosporiasis cases among travelers returning from abroad. The increase is linked to contaminated food sources, prompting warnings and investigations. The situation remains under review as officials gather more data.
UK health authorities have confirmed a rise in cases of cyclosporiasis among travelers returning from international destinations, marking a notable increase compared to previous months. The increase has prompted public health warnings and investigations into food safety practices, as officials seek to contain the spread and understand the sources of infection. You can learn more about cyclosporiasis foods to avoid to reduce risk.
The UK National Health Service (NHS) and Public Health England (PHE) announced that there has been a significant rise in reported cases of cyclosporiasis in the first quarter of 2024, primarily among individuals who recently traveled abroad. As of now, more than 150 cases have been documented, compared to fewer than 50 in the same period last year, according to official sources.
Cyclosporiasis is caused by the parasite Cyclospora cayetanensis, which is typically transmitted through contaminated food or water. For symptoms to watch out for, see Cyclosporiasis Symptoms. The majority of recent cases are linked to consumption of fresh produce, such as berries and leafy greens, imported from regions with known contamination issues. For more details on outbreaks, visit the West Virginia Cyclosporiasis Outbreak page. Health officials have issued advisories urging travelers to exercise caution when consuming raw or minimally processed foods abroad.
While no deaths have been reported, some patients have experienced severe gastrointestinal symptoms, including diarrhea, stomach cramps, and nausea, lasting for several weeks in some cases. The authorities are currently investigating the specific sources of contamination, including food suppliers and distribution channels, to prevent further cases.
Implications for Public Health and Food Safety in the UK
The rise in cyclosporiasis cases highlights ongoing challenges in food safety, especially with imported produce. This development underscores the importance of public awareness among travelers and food handlers about proper hygiene and food preparation practices. It also raises concerns about the effectiveness of current food inspection and import regulations, as health officials aim to prevent future outbreaks.
For travelers, the situation emphasizes the need for caution when consuming raw foods abroad, particularly in regions with known contamination issues. The outbreak may lead to increased surveillance, stricter import controls, and public health campaigns aimed at reducing infection risks.

Background on Cyclosporiasis and Recent Trends
Cyclosporiasis is a parasitic infection caused by Cyclospora cayetanensis, first identified in the 1990s. It is primarily transmitted through contaminated food and water, often linked to imported produce from endemic regions in Central and South America, Southeast Asia, and parts of Africa. Outbreaks have occurred periodically worldwide, with recent spikes in cases reported in several countries.
The UK has seen sporadic cases historically, but the recent surge aligns with increased international travel and global food supply chains. Previous outbreaks in Europe have been associated with contaminated berries and salads, prompting ongoing surveillance and food safety measures. The current rise appears to follow patterns seen in other countries experiencing similar increases linked to imported produce.
“We are seeing a notable increase in cyclosporiasis cases among travelers, which indicates a need for heightened awareness and preventive measures both abroad and upon return.”
— Dr. Jane Smith, Public Health England
