Reduction of S. Typhimurium viability following exposure to solutions of 2.5% sodium acetate (SA), sodium lactate (SL), and sodium propionate (SP) at pH 4 relative to the control treatment (dH₂O, pH 4) at the four temperatures indicated. Error bars indicate standard deviations. Each of the experimental factors temperature and organic acid contributed significantly to the reduction of S. Typhimurium (P ≤ 0.05). Letters above the bars represent statistically significant differences within each temperature.
