Tracing of Selected Viral, Bacterial, and Parasitic Agents on Vegetables and Herbs Originating from Farms and Markets

Original language description

Fresh vegetables and herbs are usually prepared and eaten raw without cooking or heating, which leads to a high risk of foodborne infection. The aim of the present study was to assess the contamination of raw vegetables, herbs, and the environment of food chains. Vegetable and herb samples originating both from the Czech Republic as well as from other countries were examined. The work was focused on the detection of commonly found, but also less frequently monitored foodborne pathogens, including viruses of the genus Norovirus (NoVs), hepatitis A virus (HAV), Listeria monocytogenes and Cronobacter spp. bacteria, and the parasites Cryptosporidium spp. and Giardia intestinalis. All samples were analyzed using individual RT-qPCR/qPCR assays; bacterial pathogens were also simultaneously detected using culture methods. The prevalence of the studied microorganisms in 623 samples ranged from 0.6% to 44.3% for individual pathogens. None of the samples were positive for the presence of HAV. Analysis of 157 environmental samples from 12 farms revealed the presence of NoVs in the environment of four farms. NoVs were detected in water samples as well as on the hands and gloves of workers. Escherichia coli was detected in all farms in the environmental samples and in eight farms in water samples. However, no sample of water exceeded the level of 100 CFU/mL for E. coli. None of the samples of water were positive for the presence of the studied parasites. Vegetables and herbs available from Czech markets andfarms may pose a certain risk of foodborne disease, especially in the case of NoVs and parasites.
