Listeria is a common environmental microorganism and while certain strains can be pathogenic if present in sufficient number and are exposed to high risk populations, there has not been outbreaks from fresh leafy greens eaten as such. In this report, really only one of the sample organisms was deemed as pathogenic, but the level of organism present would not likely to be sufficient to cause an issue.
That said, the produce industry has been working to ensure the risk is minimized through basic GMPs and sanitation. However, more work is needed to improve risk reduction of this organism in food operations including fresh produce. More research is needed to better understand this organism in food operations as well as in retail operations.
