The patty production process entails a great deal of handling, and therefore hygiene in these products is a concern for public health given their association with enteric diseases (Karr, Maretzki, & Knabel, 1994).
Fig. 2 shows the microbial counts in raw burgers added with PFA.
The samples added with PFA showed lower counts of aerobic mesophilic bacteria and enterobacteria (p b 0.05) than the control samples with no statistically significant differences (p N 0.05) between the 2.5% and 5% PFA samples.
