The entire detection process of this method only took 5–6 h, demonstrating its high efficiency. The nested multiplex PCR system could be successfully applied to detect actual samples, and a 90% detection rate for those three pathogens in selected <i>C. morifolium</i> was achieved.

The study was conducted in Merawi town from February 2019 to May 2019. It included 16 workers from five avocado juice houses for hygienic practice assessments. A total of 30 avocado fruit juice samples were collected for laboratory analysis. The samples were immediately transported to Bahir Dar University, Microbiology Laboratory for microbial culture. The results of the study were analyzed using descriptive statistics such as frequency, percentage, mean, and standard deviation. One-way ANOVA was used to compare microbial mean counts.

All juice vendors (100% of participants) reported that they had not received food hygiene and safety training. About 81.25% of participants did not wear safety clothes during juice processing.
