For ground chicken and ground turkey, Salmonella was reduced by 1.1 and 0.9 log CFU/g, respectively. |

PAA was found to be an effective antimicrobial agent, not only in reducing the number of pathogens in ground chicken, but also in postchill water. Treating chicken skin with PAA prior to inclusion in ground chicken can be an effective intervention strategy to lessen contamination in a ground chicken meat product. |

Both concentrations of PAA (0.07 or 0.1%) provided a 1.5-log reduction on Salmonella and Campylobacter. Chlorine at 0.003% and ASC at 0.07% were the least effective antimicrobials, providing less than 1-log reduction for both pathogens, which did not differ from the reduction provided by a water rinse alone. Results from this study indicated that using PAA and CPC in a postchill decontamination tank are effective treatments for reducing Salmonella and Campylobacter on chicken parts, with minimal effects on product quality. |

Interestingly, the addition of chitosan had a significant inhibitory effect on E. coli at 4 C and S. enterica at 10 C as compared with the control (inoculated samples) resulting in dramatic reductions in E. coli (2 log) and S. enterica (5 log) cell counts on day 21. Of all the treatments examined, citrus extract in combination with chitosan showed an additive inhibitory effect against both pathogens, reducing E. coli and S. enterica populations, by approximately 2.7 or 4.5 and 2.2 or 5.6 log cfu/g, respectively, at 4 and 10 C on day 21 of storage. |

Results of the second study showed that there was an interaction (P < 0.05) between antimicrobial type and storage time. Efficacy against Salmonella at 0 h increased in the order CPC < SSS < PAA; however, after 24 h of aerobic storage, pathogen counts of SSS- and PAA-treated wings did not differ (P > 0.05). Overall, the results indicated that SSS applied at pH 1.1 for 20 s was an effective antimicrobial intervention to reduce Salmonella contamination on chicken wings. |

In addition, 30 mg/L of sAEW was as effective as 60 mg/L of AEW in the reduction of microorganism counts. These findings indicate that sAEW may be a promising substitute for traditional sodium hypochlorite in the decontamination of chicken carcasses during slaughter, which may also help poultry companies minimize production costs in carcass decontamination. |

At concentration of 1.24%, the total plate cont was reduced 2.4 log cycles. High acid concentrations were more effective than lower concentrations. Maximum reduction due to lactic acid was at 4.25% concentration, which may result in tissue discoloration. Chlorine: There was no significant difference between different pressures and concentrations. This study found relatively low reductions of less than 1 log. TSP: Maximum reduction was 1.8 (total plate count) and 1.7 (coliform count) log cycles. Did not affect Salmonella spp. Suggests that TSP is not effective in poultry at these concentrations and pressures AvGard: Maximum reduction of 2.3 (total plate count) and 1.3 (coliform count) log cycles. Efficacy was not significant at any pressure and concentration combination. May effect levels of Salmonella spp. more than total bacterial load, but there was no distinct pattern of efficacy. AvGard does not appear to be highly effective in poultry carcasses at levels in this study. |

The results with regard to long-term freezing for 52 weeks revealed C. jejuni reductions of ca. 4 and 0.5 log10 CFU/g on wings held at -20 and -86°C, respectively. C. jejuni reductions of 0.5 log10 CFU/g for wings held at -80 degrees C, 0.8 log10 CFU/g for wings held at -120 degrees C, 0.6 log10 CFU/g for wings held at -160 degrees C, and 2.4 log10 CFU/g for wings held at -196 degrees C. The superchilling of wings to quickly cool meat to -3.3 degrees C (internal temperature) can substantially reduce C. jejuni populations at -196 degrees C when the wings are submerged in liquid nitrogen, but not at -80 to -160 degrees C when the wings are treated with vapor-state liquid nitrogen. |

Treating water heavily contaminated with chicken feces with 3% levulinic acid plus 2% SDS reduced Salmonella populations by > 7 log CFU/ml within 20 s. The use of levulinic acid plus SDS as a wash solution may have practical application for killing foodborne enteric pathogens on fresh produce and uncooked poultry. |

Interest in reduction of Campylobacter jejuni. | Treatment Concentraptions: Tartaric acid: 2% Lactic acid: 2.5% Formic acid: 2% Trisodium phosphate: 10% Caprylic acid sodium salt: 5% Capric acid sodium salt: 5% Grapefruit seed extract: 1.6% Chlorhexidine diacetate salt hydrate: 1% Cetylpyridinium chloride: 0.5% Benzalkonium chloride: 1% Chemical Treatment: Chemical solutions were kept at room temperature. Samples were dipped in treatment for 15 sec, 1 min, 5 min or 15 min. Some samples were dipped then stored for 24 hours at 5°C before quantification. | i) Treatment of skin samples for 1 min using tartaric acid (2%) and caprylic acid sodium salt (5%) were not statistically different from sterile water. ii) Statistically larger reductions (1.57 to 3.81 log) were caused by formic acid (2%), lactic acid (2.5%), trisodium phosphate (10%), capric acid sodium salt (5%), grapefruit seed extract (1.6%), and chlorhexidine diacetate salt hydrate (1%). iii)The most effective compounds were cetylpyridinium chloride (0.5%) and benzalkonium chloride (1%) However, when these treated samples were stored for 24 h at 5 C, cetylpyridinium chloride, benzalkonium chloride, and grapefruit seed extract were less effective. iv) treatment time for 15 min resulted in higher effectiveness of trisodium phosphate and formic acid. |
