U.S. food safety officials have stepped up an investigation into a Cyclospora outbreak related to lettuce, which has since expanded to nine states. The outbreak has spurred renewed worries about tracking produce in the supply chain.
Dozens of people have reportedly fallen ill. Cyclospora is a tiny pathogen that leads to an intestinal infection called cyclosporiasis. Most cases are not severely dangerous, but symptoms of the infection can persist in the gastrointestinal system for some time and need medical intervention. Cyclosporiasis is commonly linked to contaminated products like fresh vegetables and fruit before distribution, making it important to quickly determine the origin.
Health authorities say investigators may have linked the illnesses to lettuce eaten in the several locations. The miles of possible Salmonella-tainted greens being estimated, spance of nine. Epidemiologists are working hand-in-hand with food safety authorities to track down the market origins of the green import. The flea market includes tracing shipments from farms to wholesalers, restaurants and retail stores.
Infected persons with Cyclospora often have symptoms of diarrhea that can last for a couple of weeks, cramps in the stomach area nausea tiredness, inability to tolerate food and feeling bloated. They may also have a low fever. Symptoms can take a couple of days to appear after intake of the contaminated food. They can last for a couple of weeks if not treated.
Due to the nature of the symptoms, diagnostic testing, is usually required. CDC also stresses that the bug itself sets Cyclospora apart from many other bacteria causing foodborne illnesses. The parasite needs to spend a time period before it is mature enough to infect another host after being introduced into the environment, Because of this early direct transmission between people is viewed as rare. Instead, most cases can be tied back to tainted water or food, often raw vegetables.
This study demonstrates the difficulty in maintaining food safety at all levels of the food supply chain. Fresh leafy vegetables on common grocery shelves are most likely to have been harvested packaged transported, and distributed by many different people and companies before entering our homes.
If a fault is discovered, it may take some time to trace the origin of contamination and begin necessary corrective actions on the part of farmers distributors retailers, or government bodies. Health officials are conducting interviews with current patients to identify common foods exposures and sources.
Mapping of those findings may enable investigators to narrow down which lettuce is infected or contaminated, and determine if further displays or recalls should be issued. Food safety laboratories are testing samples for the parasite. Until the investigation is over, purchasers are advised to follow ordinary hygiene guidelines about food consumed. Washing properly under running water, keeping vegetables at home at recommended refrigerator temperatures and following recall notices for products under suspicion all do mitigate the effect of foodborne infection.
It has Still been said that washing “may not eradicate all evidence of this parasite since Cyclospora is able to cling tightly to leaf surfaces”. Health professionals should remain vigilant for patients presenting with persistent gastrointestinal symptoms Mainly if they have recently eaten raw salad or leaf vegetables. Prompt diagnosis will enable clinicians to treat the individual patient reducing illness duration.
