“…A serial dilution of the vegetable and river water samples was made by transferring 1 mL of suspension and adding it to the tube containing 9 mL of sterilized peptone water. 31 , 33 Then, the Total Bacterial Count (TBC) and Total Coliform (TC) were determined by spreading 0.1 mL of suspension and spreading it onto sterile Petri dishes containing sterile Plate Count Agar (Oxoid, UK) and MacConkey agar (Oxoid, UK), respectively. The plates were incubated at 37℃ for 24 hours.…”

background: Cultivation of vegetables using untreated wastewater is a common phenomenon in many drought-prone areas of the world. Consumption of such microbiologically unsafe vegetable increase the risk of food-borne diseases. As a result, evaluating the effect of wastewater irrigation on the microbiological quality of vegetables would be beneficial to consumers’ health. method: A total of 192 vegetable samples (lettuce, cabbage, carrot, and tomato) and 64 irrigation water samples were collected and analyzed for total bacteria and coliform count using a standardized protocol over a 4 month period. One-way analysis of variance and Pearson correlation coefficient was used to analyze the data. Statistical significance was defined at a P-value of less than 0.05. result: Carrots were the least polluted vegetable, according to the study, while cabbage had the highest contamination levels. The mean bacterial count among the vegetables differs significantly ( P < 0.05). The fecal coliform counts of the irrigation wastewater exceed the international wastewater irrigation standards. The mean microbial count between vegetables and water samples showed a significant positive relationship ( P < 0.05). All of the analyzed vegetable samples were of borderline microbial quality for fecal coliform bacteria. conclusion: Irrigation wastewater has a low microbiological quality, which significantly contributes to the contamination of vegetables grown on it. recommendation: Measures should be taken to improve the microbial quality of wastewater as well as the quality of vegetables grown in order to protect consumers’ health from food-borne diseases.

The demand for organic products has increased with the increase in individuals’ education and income levels, their sensitivity to the qualityof the products, and their willingness to pay higher prices for natural and quality products. Confidence in organic products, caring aboutthe health effects of organic products, and the ease of accessing them are among the factors that increase their consumption. Organicproducts are also perceived as natural products in Turkey. The awareness of questioning the certificates and logos of purchased organicproducts has not yet been formed. Those who do not know the legislation, such as the organic logo requirement, perceive all kinds ofnatural products obtained from rural areas as organic. In this study, 477 questionnaires from households were obtained in Bursa, the4th largest city in Turkey. The study aimed to reveal organic milk and dairy products (OMDP) consumption perceptions, consumption status,and reasons for preference by participants’ income level. Consumers’ awareness and perceptions of OMDP, their OMDP consumptionstatus, and the relationship between OMDP consumption and income level. The study also inquired whether consumers would be willingto pay more for OMDP and whether this willingness to pay was affected by income levels. Middle-income consumers consumed the mostorganic milk—consumers with high income purchased OMDP the least. However, in case of increased product awareness, half of thehigh-income consumers were willing to pay 30% more for OMDP. This research is a reliable, empirical field study to reveal Turkish OMDPconsumers’ characteristics and contribute to the literature.

“…Even though raw milk is considered as relatively free from contaminants when it leaves the udder, it is highly prone to the invasion of various exogenous pathogenic bacteria [ 22 , 26 , 27 , 36 , 37 ]. It has been reported between 2006 and 2012 that twenty outbreaks of illness have been associated with the consumption of raw milk in New Zealand [ 27 ].…”

Background Raw milk may contain pathogenic microorganism that can sometimes fatally affect the health of consumers. However, risks related to raw milk consumption in Southwest Ethiopia are not well studied. The aim of this study was to evaluate the presence of five target pathogenic bacteria including Escherichia coli O157:H7, Salmonella enterica Typhimurium, Staphylococcus aureus, Listeria monocytogenes, and Campylobacter jejuni in raw milk and to assess exposure associated with the consumption of raw milk. Method A cross-sectional study was carried out between November 2019 and June 2020 to in Jimma zone, Southwest Ethiopia. Laboratory analysis was conducted on milk samples collected from Seven Woreda towns, including, Agaro, Yebu, Sekoru, Serbo, Shebe, Seka, Sheki and Jimma town administration. Semi-structured interview questions were administered to collect data on the amount and frequency of consumption. Descriptive statistics were used to summarize laboratory results and questionnaire survey data. Result Among 150 total raw milk samples, about 61.3% were found contaminated by one or more types of pathogens along the dairy value chain. The highest and the least bacterial counts recorded were 4.88 log10cfu/ml and 3.45 log10cfu/ml from E. coli and L. monocytogenes respectively. The mean concentrations of pathogens demonstrated significant statistical difference (p < 0.05) using 95% confidence interval where the prevalence percentage of isolates increased as the milk was transported from farms to the retail outlets. Except for C. jejuni; all other pathogens were detected in the range of unsatisfactory level of milk microbiological quality along the chain. The estimated mean annual risk of acquiring intoxication of E. coli across retailer outlets is 100% whereas salmonellosis, S. aureus intoxication, and listeriosis are 84%, 65% and 63% respectively. Conclusion The study highlights the significant health risks associated with the consumption of raw milk due to its unacceptable microbiological quality. The traditional production and consumption patterns of raw milk are the primary reasons for the high annual probability of infection. Therefore, regular monitoring and implementation of hazard identification and critical control point principles are necessary from raw milk production to retail points to ensure the safety of consumers.
