Effects of intensity and processing time of 254 nm UV irradiation on Listeria monocytogenes, Escherichia coli O157: H7, and Salmonella Typhimurium were investigated. Intensities measured at 5.08, 10.1, 15.2, and 20.3 cm from the light source were 1,000, 500, 250, and 150 μW/cm2, respectively. Intensities of 250 or 500 μW/cm2 reduced all suspended pathogen cells in peptone water about 5 log cycles after 2 min and completely inactivated L. monocytogenes and E. coli O157:H7 after 3 min by reductions of 8.39 and 8.64 log cycles, respectively. Intensities of 250 or 500 μW/cm2 also reduced (P ≤ 0.05) the tested pathogens inoculated on stainless steel (SS) chips, and E. coli O157:H7 was completely destroyed at 500 μW/cm2 for 3 min. After UV treatment for 3 min at 500 μW/cm2, all selected pathogens on chicken meat with or without skin showed reduction ranges from 0.36 to 1.28 log cycles. Results demonstrated that UV irradiation could effectively decrease pathogens in peptone water and on SS but that it was less effective on chicken meat.

Abstract Escherichia coli O157 related foodborne illnesses continue to be one of the most important global public health problems in the world. This study aims to determine E. coli O157 prevalence in 375 chicken meat parts and giblets. The samples were collected randomly from several supermarkets and butchers in Diyarbakir, a city in southeast Turkey. They were analyzed and confirmed using the immunomagnetic separation (IMS), Vitek® 2 microbial identification system and polymerase chain reaction (PCR) method. This study also aims to detect the presence of fliCH7, eaeA, stx1, stx2 and hlyA genes by using PCR. The overall E. coli O157 prevalence in chicken meat parts and giblets was 1.3%. All of the E. coli O157 isolates carried rfbEO157 and eaeA genes; but not any fliCH7 and hlyA genes. The E. coli O157 isolates obtained from drumstick and breast meat carried either stx1 or stx2 genes, which were related to important virulence factors of the disease.

A total of 143 samples of meat were examined in this study, theserepresents 67 samples of locally minced meat, 31 samples of importedminced meat and 45 samples of imported chicken meat. The samples werecollected from different areas of Baghdad city during the period fromJanuary till May 2006.Detection, isolation an enumeration of E.coli 0157:H7 were carried out.The result revealed that there was a significant difference (P < 0.05) in theisolation percentage and the microbial counts of E.coli 0157:H7 whencomparing the three types of meat. The highest prevalence were found in thelocally minced meat (80% ; 1.6 x 107 cfu/g) Followed by the importedminced meat (65% ;5.9x106cfu/g) and finally chicken meat(56%; 2.7 x 106 cfu/g).

Mutagenic Effects

Abstract The main bactericidal components of cold atmospheric plasma (CAP) are thought to be reactive oxygen and nitrogen species (RONS) and UV radiation, both of which have the capacity to cause DNA damage and mutations. Here, the mutagenic effects of CAP on Escherichia coli were assessed in comparison to X- and UV-irradiation. DNA damage and mutagenesis were screened for using a diffusion-based DNA fragmentation assay and modified Ames test respectively. Mutant colonies obtained from the latter were quantitated and sequenced. CAP was found to elicit a similar mutation spectrum to X-irradiation, that did not resemble that for UV implying that CAP produced RONS are more likely the mutagenic component of CAP. CAP treatment was also shown to promote resistance to the antibiotic ciprofloxacin. Our data suggest that CAP treatment has mutagenic effects that may have important phenotypic consequences.

Exposure To Cold

To evaluate the effect of sub-lethal exposure to cold atmospheric plasma (CAP) on their antibiotic resistance, Methicillin Resistant Staphylococcus aureus, S. epidermidis, Pseudomonas aeruginosa, Escherichia coli, Streptococcus mutans, and Candida albicans were exposed in vitro to a commercially available CAP. This antimicrobial CAP inhibited growth but changed survivors’ antibiotic resistance.
