Similarly, in 2008, Nesbakken et al. reported 56.7% and 1.7% prevalence before and after blast freezing of the carcass [36]. Similarly, in 2003, Pearce et al. detected the prevalence rate of 33% in carcass prior to chilling and 0% in chilled carcass [18]. So, lack of chilling the carcass is identified as a risk factor for prevalence of campylobacters in dressed pork. The prevalence
rate in slaughter slab where contamination of carcass with intestinal content occurs sometimes was significantly higher compared to the slaughter slab where such contamination never occurred (p < 0.01). This is due to the fact that the intestinal content of pig is highly contaminated with Campylobacter[8, 19, 30]. So, contamination of carcass with intestinal content is another risk factor for prevalence find more of campylobacters in pork. The prevalence of Campylobacter spp. from slaughter slabs and retail shops where wooden chopping board (Achano) was not cleaned daily was significantly higher (p < 0.05) compared to those cleaning the chopping wood (Achano) daily. This shows that chopping wood used in slaughter slab could be potential source of Campylobacter contamination but samples from DMXAA clinical trial these equipments were not cultured for confirmation. So, further research is needed for confirmation. Lonafarnib in vitro Similarly significant difference (p < 0.05) in
the prevalence of Campylobacter spp. was observed between the pork meat shop that regularly cleaned the weighing machine and others that do not clean weighing machine regularly. So, slaughtering equipments are also risk factors for campylobacter contamination in pork. Oosterom et al. in 1985, ICMSF in 1998 and Pearce et al. in 2003 have also regarded slaughtering equipments as
important risk factors for cross contamination of campylobacter in pork [18, 35, 37]. The MAR index for the isolated campylobacters is very high in this research which is suggestive of public health hazard. All of the isolates are resistant to at least one of the most of commonly used antibiotics included in this study. More importantly, 28.6% of the isolated C. coli were resistant to six different antibiotics and 21.4% were resistant to seven different antibiotics used in the study. This implies severe dipyridamole threat to public health. Likewise, 41.7% of the isolated C. jejuni were resistant to seven different antibiotics used in the study. The reason behind this may be due to excessive use of antibiotics in pig for treatment as well as growth promoter. The other reason may be due to environmental cross-contamination through other risk factors such as contact with reservoirs like human. This shows that Nepalese people are constantly consuming multiple antibiotic resistant campylobacters in their diet through pork meat. Ery-Amp was the most common resistant pattern (85%) regardless of the species whereas, Thakur and Gebreyes reported ery-tet as most common resistant pattern (60.
