A recent study conducted by scientists at the University of Kent has revealed the presence of cryptosporidium, a waterborne disease, in pre-washed vegetables being sold in Kent. Cryptosporidium, known to cause symptoms like diarrhea and sickness, was found in 17% of the samples analyzed.
The research, led by Dr. Anastasios Tsaousis from the university’s School of Biosciences, suggests a potential need to review sanitation methods employed by suppliers in the production chain. Dr. Tsaousis emphasized the importance of consumer awareness regarding proper vegetable storage and handwashing practices.
The pilot study, conducted between May and July 2023, examined 36 pre-washed vegetable bags containing a variety of produce. However, the study could not differentiate between ‘live and inert’ cryptosporidium particles.
Cryptosporidium, a parasite that can infect both humans and farm animals, typically manifests through symptoms such as diarrhea, vomiting, stomach pains, and fever. The parasite is commonly found in natural water sources like lakes, streams, rivers, and untreated drinking water.
While pre-washed vegetables undergo more extensive washing with chlorine disinfectants compared to unpackaged produce, cryptosporidium particles have shown resistance to chlorine disinfection. The research suggests that boiling water or filtration are more effective methods of removal.
Dr. Tsaousis recommended that suppliers consider enhancing hygiene measures throughout the harvesting, processing, packaging, transportation, and storage stages to mitigate the risk of contamination. Recent instances of cryptosporidium contamination in drinking water have led to precautionary measures such as boiling water advisories in affected areas.
Residents in Devon have been advised to boil their water following the detection of cryptosporidium in the water supply. Approximately 2,500 homes in Brixham remain under a boil water notice as a result of the outbreak.
As concerns around cryptosporidium contamination persist, it is crucial for both suppliers and consumers to prioritize hygiene practices and water safety to prevent the spread of this waterborne disease.
