A review paper published in the journal Foods describes a study that provides an overview of studies on minimally processed vegetables (MPVs), with a particular focus on the Brazilian market.
Data is presented on hygiene indicators and pathogenic microorganisms, especially Escherichia coli (the main indicator of fecal contamination), Salmonella spp., and Listeria monocytogenes, with prevalence rates ranging from 0.7 per cent to 100 per cent, 0.6 per cent to 26.7 per cent, and 0.2 per cent to 33.3 per cent respectively.
The article also discusses outbreaks of food-borne disease (food poisoning) associated with consumption of fresh vegetables in Brazil between 2000 and 2021. “Although there is no information about whether these vegetables were consumed as fresh vegetables or MPVs, the data highlights the need for control measures to guarantee products with quality and safety for consumers,” the authors write.
Regular consumption of vegetables plays an important role in human nutrition owing to the vitamins, minerals and fiber they contain. “More and more people want healthy food that can be prepared in a short time because of the hurry and stress of everyday life. This trend has led to rising global demand for MPVs."
"On the other hand, fresh vegetables and MPVs are frequently associated with food-borne diseases. The link is a matter of concern. MPVs are sanitized and disinfected, but studies show this process can be flawed, putting consumer health in danger. Rigorous controls are needed to avoid flaws and cross-contamination,” said Daniele Maffei, last author of the article.
