In that same experiment, in the presence of the raw meat
autochthonous bacterial flora, modified atmosphere and oregano EO,
L. monocytogenes concentration diminished below the detection limit
over the shelf-life (Tsigarida, Skandamis, & Nychas, 2000).
Our research
has demonstrated that antimicrobial effect of EO can still be detected
when using lower concentration (500 ppm)
