“…Although the total Enterobacteriaceae count found in the present study was far more than 10 3 log CFU/g, which according to the Dutch standard was considered as limit value for the total number of Enterobacteriaceae in fresh fish [15,16], results are in accordance with the fact that CO2, primarily in high concentrations, acts inhibitively on Gram negative bacteria, including Enterobacteriaceae. In accordance with the present study are results of others [17,18,19,20,21], in which the influence of MAP on fresh fish was examined, and which came to the conclusion that high levels of CO2 in the package (>50%) have a protective effect on the product and consequently, reduce both the total Enterobacteriaceae count as well as the total number of bacteria.…”
