The Salmonella spp. were traced by using selective cultivation
on XLD agar, as it has a shiny black centre in the colony (Fig. 3d).
In the control conditions, Salmonella spp. was at the level of
2–3 logCFU/g during 7 days of storage. On the first day, the
Salmonella spp. growth was 2 logCFU/g for the sample treated
with 0.2% OligoC, whereas it is found to be not detected for the
sample treated with 0.4% OligoCS. After 2 days of storage, the
Salmonella spp. growth in the sample containing 0.2% OligoCS
was not observed. The result reconfirmed the efficacy of OligoCS
on Salmonella spp. inhibition as previously observed in vitro.
