Abstract
Campylobacter is considered to be one of the major pathogens responsible for food poisoning that occurs particularly after consuming the incorrectly stored or improperly thermally treated poultry meat. Thus, research studies are intensified that are targeted at searching for disinfection techniques, which are environmentally safe and effectively eliminate that pathogen. The Department of Food Quality at the Institute of Agricultural and Food Biotechnology in Łódź undertook research the objective of which was to determine the effectiveness of environmentally friendly disinfection with the use of ozone and ultraviolet irradiation to inactivate Campylobacter sp. inoculated on agar plates, and, then, in poultry meat. It was proved that the two disinfecting agents caused the counts of Campylobacter spp. to decrease. When applying the method with agar plates, the reduction degree of bacteria was above 2 log cfu /ml regardless of the strain and sanitising agent. After 30 minutes of sterilizing the poultry meat, the reduction degree of bacteria therein ranged from 0.19 log cfu / ml as for the strain of UV irradiated C. coli ATCC 43478 to 1.16 log cfu /ml as for the ozone-treated C. jejuni (the authors’ own strain). Depending on the disinfecting agent: ozone or UV light, the mean degree of reduction was, respectively: 1.0 and 0.3 log cfu/ml UV. Considering the results obtained, it would not be recommended to apply only one of the disinfection methods tested to the initial cleansing process of poultry. However, the use of ozonation and UV irradiation together with other decontamination techniques could increase the effectiveness of sanitisation and improve the microbiological safety of poultry meat; therefore, it is advisable to continue the research in this field.
