“…The temperature of the milk decreased in all seasons, and the bacterial count during the summer was higher compared to the rainy and winter seasons (5,812 log10 CFU ml -1 , 5,743 log10 CFU ml -1 , and 5,713 log10 CFU ml -1 , respectively). In a study where evaluated the microbiological quality of milk at different stages of the dairy value chain from the farm to the factory to identify contaminating microorganisms were evaluated, reported similar results; the findings related the loss of quality in the centers of production with an average coliform count of 7.1 x 10^4 CFU ml -1 (Islam et al, 2018). Recommending greater attention in conservation during transport since at this stage, the proliferation of microorganisms can increase rapidly (Bonfoh et al, 2003).…”

Introduction. The production and commercialization of raw milk in Nariño, Colombia, follows microbiological and compositional standards on which payment for quality is made. However, quality can be affected during its transport after milking. Objective. To describe the microbiological and compositional quality of raw milk in the highland tropic. Materials and methods. The study was carried out in seven municipalities in the department of Nariño, Colombia, during the rainy season between February and July of 2017. Two milk samples from the same milk can were collected, one after milking (farm; n = 10), and the second at the collection point (tank; n = 10). In each sample, the following variables were evaluated: height above the sea level of the collection site, aerobic mesophilic count (CFU), total coliform count (COL), milk temperature, fat (FAT), protein (PC) and total solids (TS). Results. The temperature of the milk was higher on the farm compared to the tank (30±0.68 vs. 23±0.87 °C, respectively). The aerobic mesophilic count was higher in the tank vs. farm (116,470 vs. 41,388 CFU ml-1, respectively). The temperature of the milk was negatively correlated with the distance and the transport time of the milk (-0.86 and -0.84, respectively). The compositional quality of the milk was not affected by transport conditions. Conclusion. In the high tropic conditions, the microbiological quality of raw milk was negatively affected by the increase in the aerobic mesophilic counts.

“…Not surprisingly, in an emerging economy like Bangladesh, when consumers buy LM they are exposed to potential risks and hazards. This phenomenon is more concretely illustrated in a recent finding by the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR, B), an international health research organization located in Dhaka, Bangladesh, that more than 75% of all pasteurized milk available on the local market is unsafe for direct consumption [51]. Unfortunately, for general consumers, assessing the risk associated with food is difficult through their normal judgement and discretion, and for this reason a consumer has often to rely on various information sources such as the media, institutions or vendors, etc.…”

Until today, inadequate food supply, malnutrition, food adulteration, etc., are still the key concern in developing economies. In order to address these issues of food security crisis, and to stimulate a sustainable supply of liquid milk (LM), a consumer behavior model was created, in which consumers’ perceived knowledge, trust and risk were the major catalysts. To shed light on this context, the study examined the effect of consumers’ perceived knowledge (PK) on their perceived risk (PR) and trust (in information sources and in the product). Further, the influence of consumers’ perceived knowledge, risk, and trust on their attitude and purchase intention (PI) were investigated via an exclusive survey design. The survey was conducted in the urban area of Dhaka and Chittagong, Bangladesh. The sample of 712 households was selected randomly and interviewed using a structured questionnaire. The data were analyzed employing descriptive statistics, exploratory factor analysis, confirmatory factor analysis, and structural equation modelling. The results show that during a food security crisis, consumers’ perceived knowledge amplifies their perceived risk and their trust in information sources (ISs). During such a period, their perceived knowledge does not induce purchase intention but trust in ISs does. Again, consumers’ perceived risk leads to reduced trust in products, and hence in LM, but not reduced trust in ISs. Moreover, a paradoxical influence was found, where consumers’ perceived risks had no significant effect on the PI, meaning that they underestimate the risk of purchasing LM. The results also show that when explaining the purchase intention of LM, the effect of ‘trust in ISs’ was higher than that of their perceived ‘trust in the product (LM)’ and perceived knowledge.

“…On the other hand, demand for liquid milk, according to the different reports in the literature, is affected negatively because the availability of pure and safe liquid milk (LM) from a reliable source is low in developing countries like Bangladesh [ 12 ]. Research shows that although households are less price sensitive in purchasing functional foods, in this case, quality and safe LM, they cannot avail themselves of their desired milk [ 13 ], since almost all of the milk samples, both raw and processed (both pasteurized and Ultra High Temperature (UHT)), are adulterated in many different ways, such as mixing water, cane sugar, powdered milk, starch, formalin or sodium bicarbonate [ 14 ], and are highly contaminated with fecal organisms [ 15 ]. Furthermore, since marketers have been supplying adulterated milk to meet the excess demand, regrettably, consumers are confused and they have less scope to believe that this LM is safe and fresh.…”

“…Additionally, the need for nutritional and quality food puts stress on vendors to supply unadulterated food [ 27 ], since to reach our genetic potential we have to drink milk regularly [ 34 ]. However, almost all sampled fresh milk traded on the Bangladeshi local market is adulterated [ 15 ]. One study has revealed that Asian consumers are health conscious when they reconsider drinking wine [ 35 ].…”

This study is based on the influence of consumers’ health consciousness (HC), perceived knowledge (PK) and beliefs affecting the attitude and purchase intent (PI) of the consumers. The outcome of this study is obtained through an exclusive survey conducted on a randomly selected sample of 712 households who purchase liquid milk (LM) in the cities of Dhaka and Chittagong in Bangladesh. A structured questionnaire is used to interview these participants to obtain data which are analysed employing descriptive statistics, Confirmatory Factor Analysis, and Structural Equation Modelling. The results of the analyses corroborate that consumers’ health consciousness has a positive impact on perceived knowledge, belief, and attitude, but not on purchase intent. In addition, belief affects both the attitude and PI positively. Although consumers’ perceived knowledge is too low to constitute their attitude towards LM, it has a positive, significant impact on the PI. The results also reveal that more than a third of the respondents consume LM several times per month, followed by more than a quarter of the sampled respondents who consume LM several times per week, and these consumption patterns have a positive and significant influence on the PI. Moreover, the monthly income of the family, age, and labelling preference are significantly correlated with PI.
