Early findings from researchers in Spain has found organic produce can be contaminated with a range of bacteria.
The study suggests that amoebas that live on organic leafy vegetables can shelter human pathogens like Pseudomonas, Salmonella, and Helicobacter.
Details are based on a poster presentation at the European Congress of Clinical Microbiology and Infectious Diseases (ECCMID) in Lisbon, Portugal, from April 23 to 26. All abstracts were peer reviewed by a congress committee. There is no paper yet, but the research has been submitted to a medical journal for publication.
However, other scientists warned that while conclusions are interesting, the fact that data has not yet been peer reviewed means they cannot be put into context.
