The antimicrobial efficacy of carvacrol, trans-cinnamaldehyde, eugenol and thyme oil (0.5, 1, 2 and 5% v/v) was evaluated against Salmonella on turkey breast cutlets as 2 min dip treatments at 4°C. Carvacrol revealed maximum efficacy against Salmonella on turkey cutlets and was selected for 30s and 60s dip treatments at 4°C. Only 5% carvacrol was effective and exhibited 1.0 and 1.8 log CFU/g reduction of Salmonella with 30s and 60s dip treatments, respectively. However, carvacrol showed synergistic activity with carbon dioxide in modified atmosphere packaging (95% CO2/5% O2) against Salmonella and Campylobacter and caused 1.0-2.0 log CFU/g reductions with lower concentrations (0.25, 0.5 and 1.0%). This combination reduced the growth of lactic acid bacteria. In the third experiment, efficacy of lauric arginate (200 and 400ppm) against C. jejuni was tested on chicken breast fillets. Both these concentrations significantly reduced C. jejuni on chicken fillets (1.0-1.5 log CFU/g) at 4°C.
