Which Factors Drive Consumer Decisions during Milk Purchase? New Individuals’ Profiles Considering Fresh Pasteurized and UHT Treated Milk

The cow’s milk market is going through a critical period characterised by a continuous contraction in consumption as a consequence of the lack of competitiveness on the market of the conventional product (commodity) versus numerous specialties. This paper aimed to define the profiles of milk consumers in terms of individual preferences (assessed using the best-worst scaling methodology) and socio-demographic features. A survey was conducted in several stores of large-scale retail, convenience stores, and open-air markets distributed in north-west Italy to collect data from 1216 respondents. For milk shopper purchasing habits, two consumer groups were defined and compared in terms of preferences: the fresh pasteurized milk consumer (FPc) (56% of the total sample) and the ultra-high temperature treated milk consumer (UHTc) (35%). A series of two-ways multivariate analysis of variance (MANOVA) were conducted to assess the effect of individuals’ socio-demographic characteristics and the type of milk chosen on the consumer preferences, simultaneously. Significant differences in milk purchasing habits and preferences emerged when comparing the two consumer groups (UHTc and FPc). Empirical evidence of the study supported the starting hypothesis, suggesting the significance or relevance of the consumer socio-demographic characteristic, as well as their interaction effect with the type of milk on the level of importance given to the considered milk quality attributes. On the contrary, the gender results were not significant for the milk preferences definition. The assessment of consumer preferences, associated with the individuals’ socio-demographic characteristics could have important implications for outlining more effective marketing strategies based on a more targeted communication (i.e., related to the sustainability dimension of the local product, nutritional value and brand), leading the consumer back to the commodity rediscovery concerning individuals’ features and habits.

Media Control and Citizen-Critical Publics in Russia: Are Some “Pigs” More Equal Than Others?

Amid the intensification of state control over the digital domain in Russia, what types of online activism are tolerated or even endorsed by the government and why? While entities such as the Anti-Corruption Foundation exposing the state are silenced through various tactics such as content blocking and removal, labelling the foundation a “foreign agent,” and deeming it “extremist,” other formations of citizens using digital media to expose “offences” performed by fellow citizens are operating freely. This article focuses on a vigilante group targeting “unscrupulous” merchants (often ethnic minorities and labour migrants) for the alleged sale of expired produce—the Hrushi Protiv. Supported by the government, Hrushi Protiv participants survey grocery chain stores and open-air markets for expired produce, a practice that often escalates into violence, while the process is filmed and edited to be uploaded to YouTube. These videos constitute unique media products that entertain the audience, ensuring the longevity of punitive measures via public exposure and shaming. Relying on Litvinenko and Toepfl’s (2019) application of Toepfl’s (2020) “leadership-critical,” “policy-critical,” and “uncritical” publics theory in the context of Russia, this article proposes a new category to describe state-approved digital vigilantes—citizen-critical publics. A collaboration with such publics allows the state to demonstrate a façade of civil society activism amid its silencing; while state-approved participants gain financial rewards and fame. Through Foucauldian discourse analysis, the article reveals that vulnerable groups such as labour migrants and ethnic minorities could fall victim to the side effects of this collaboration.

Relational goods and direct purchase from farmers: estimating the value of the relationship between consumers and producers

Personal relationships can affect economic life, more importantly in alternative food networks. Estimating the value of enjoyment of the relational good produced by consumers’ personal relationship in direct sales from farmers is important to assess how much personal interactions can affect food purchases. We employ different stated preferences models to estimate from a consumer survey in open-air markets in four towns in Italy the value consumers buying directly from farmers attach to their particular choice of a specific vendor. Contingent on the chosen model, the average value of the personal relationship is 13.5-24.4% of their expenditure for fruits and vegetables.

Microbial load of edible termites (macroterme spp.) from collection to marketing in Serenje District, Central Zambia

Edible insects including termites form a suitable alternative for sustainable provision of animal protein to fight protein-energy malnutrition. It is as cardinal to study the food safety of edible termites as it is for any other food stuff. Twenty seven (27) samples were collected and analysed for total viable counts and Enterobacteriaceae. The microbial load was assessed using culture, microscopic and biochemical methods. The isolates identified in this study include Staphylococcus aureus, Escherichia coli, yeasts other than Candida albicans and Zygomycetes. Investigation of the total viable counts and Enterobacteriaceae of open air traded edible termites revealed loads higher than those recommended for minced meat 5.7 to 6.7 log10 cfu/g. The mean ranges were between 6.87 and 9.29 log10 cfu/g for total viable counts and 6.64 and 8.537 log10 cfu/g for Enterobacteriaceae. The presence of E. coli suggests faecal contamination of the sample along the value chain whereas S. aureus, yeasts other than C. albicans, and Zygomycetes indicate unhygienic handling of the food samples. Heat treatments can reduce the loads but may not be effective for enterotoxins and recontamination of the sample is possible. Poor hygiene and sanitation by handlers may contribute to contamination and recontamination of Edible termites. Food safety and hygiene education on processing and handling practices that reduce microbial loads at collection sites, transportation and display points are important especially since termites are sold as ready to eat foods in African open air Markets. Legislation on open defecation, use of toilets and promotion of hand washing hygiene can effectively reduce the risk of contamination with gastrointestinal microflora from faecal matter.

Antibiotic-resistant Gram-negative Bacteria in Urban Flies, and the Increased Risk Posed by Open-air Markets in Mexico City

Aims: Flies are known to spread antibiotic resistant bacteria (ARB), especially from farms to cities; but they may also play a role in the intra-urban dispersion of ARB, in conjunction with poor sanitary conditions. Here, we characterized gram-negative ARB isolated from urban flies (Lucilia and Sarcophaga spp.), and the co-relation with the periodic installation of two open-air markets in Mexico City. Methodology: Forty-two flies were individually captured, and 116 gram-negatives (68 of them Escherichia coli) were isolated from them. Resistance prevalence, and the presence of class 1 integrons was assessed. Results: The isolates were resistant to an average of 2.26 antibiotics (2.6 for E. coli), and 33% of E. coli isolates carried the intI1 gene. Thirteen percent of E. coli isolates produced extended-spectrum beta-lactamases (ESBL), all of them CTX-M, alone or, mostly, along TEM enzymes. Comparing data from market-free days vs. days when open-air markets were installed, the average number of resistance phenotypes per E. coli isolate went from 2.14 to 3.09; the number of resistance phenotypes per fly from 4.62 to 8.88; the average number of resistances per isolate per fly from 1.25 to 2.43; and the ESBL-producing carriage rate per fly from 0.08 to 0.38, respectively (P <.05). Other resistance parameters, were consistently higher among flies captured on market days, but differences were not significant. Conclusion: Urban flies in Mexico City carry a high number of gram-negative ARB; the presence of open-air markets significantly increase the risk of fly-mediated ARB spreading to the neighboring areas.

How Field Experiments in Economics Can Complement Psychological Research on Judgment Biases

This review summarizes results of field experiments examining individual behaviors across several market settings—from open-air markets to rideshare markets to tax-compliance markets—where people sort themselves into market roles wherein they make consequential decisions. Using three distinct examples from my own research on the endowment effect, left-digit bias, and omission bias, I showcase how field experiments can help researchers understand mediators, heterogeneity, and causal moderation involved in judgment biases in the field. In this manner, the review highlights that economic field experiments can serve an invaluable intellectual role alongside traditional laboratory research.

Does Retail Food Diversity in Urban Food Environments Influence Consumer Diets?

The food environment influences consumer diets in significant yet underexplored ways. In this study, we assess the way in which the Nairobi urban food environment—availability, accessibility, affordability, desirability, convenience and marketing—influences the dietary choices and quality of poor urban consumers, by combining market-level diversity scores (MLDS) with household and individual data collected from resource-poor (slum) neighbourhoods in Nairobi, Kenya. We find that urban-poor settings are characterized by a variety of food retail venues, including informal markets such as kiosks, mom-and-pop shops and tabletop vendors, as well as modern retail outlets such as supermarkets. Most of these food outlets predominantly sell unhealthy, highly-processed and energy-dense foods rather than nutritious foods such as vegetables, fruits and animal products. Our analyses show that supermarkets have the highest MLDS, yet they do not significantly influence the diets of resource-poor households. However, a high MLDS among informal retail outlets has a positive association with diet quality; conversely, open-air markets have a negative association. The nutritional status of urban-poor consumers can be improved by promoting the diversification of healthy, nutritious foods across traditional retail outlets and improving accessibility of the outlets to consumers.

Occurrence of Intestinal Parasites in Fruits and Vegetables from Markets of Northwest Mexico

Background: Fruits and vegetables are potential vehicle of transmission of intestinal parasites. The main aim of this study was to determine prevalence of intestinal parasitic contamination in fruits and vegetables sampled from Caborca region, Northwest Mexico. Methods: A total of 400 fruit and vegetable samples were collected from unregulated open-air markets and closed (i.e., regulated) markets in Caborca region of Northwest Mexico; including melon, peach, asparagus, and grapes. Faust, Kinyoun, and Enzyme- Linked Immunosorbent Assay (ELISA) techniques were used to detect and identify the genus and species of all parasites found in the examined samples. Data were statistically analyzed using STATA/SE (version 12.0). Results: An overall prevalence (45%) of parasitic contamination was found in the 400 fruit and vegetable samples. Endolimax nana (27.5%) and Entamoeba coli (17.5%) were the most common nonpathogenic parasites, while the most prevalent parasitic pathogens were Cryptosporidium spp. (11.7%), Cyclospora spp., (11.0%), and Blastocystis hominis (9.2%). Asparagus (31%) and grapes (38.9%) had significantly (p<0.05) higher percent- ages of overall and multiple parasitic contamination than melon (10.6%) and peaches (19.4%). The fresh produce from the open-air markets had significantly (p<0.05) higher overall parasitic contamination (53.5%) than those of the closed establishments (36.5%). Conclusion: The parasitic contamination in the fresh produce sold in the Northwest region of Mexico is a serious public health concern.

Wild food plants and fungi sold in the markets of Luang Prabang, Lao PDR

Background Open air markets hold an important position for ethnobiologists. In Southeast Asia, they are seriously understudied, in spite of their incredible biocultural diversity. In order to fill this gap we recorded plants and fungi sold in the open air markets of Luang Prabang, Lao PDR. Methods The markets were visited 38 times in four seasons: the dry season, early monsoon, mid-monsoon, and end-of-monsoon, at least 8 times per season. All items were photographed and voucher specimens were collected. Fungi were identified using DNA barcoding techniques. Results We recorded 110 species of wild edible plants and 54 species of fungi, including 49 wild-collected species. The sold plants included 86 species of green vegetables, 18 species of fruits and 3 species of flowers. Products from woody species constitute around half of all taxa sold. These include the young shoots of tree leaves, which are used for salads—an interesting feature of Lao cuisine. A large number of extremely rare Russula, with no reference sequences represented in databases or even species unknown to science is present on sale in the markets. Conclusions Luang Prabang markets are some of the richest in species of wild edible plants and fungi in Asia, and indeed in the whole world. It is worth pointing out the exceptionally long list of wild edible mushrooms which are sold in Luang Prabang (and probably elsewhere in Laos). We view the Morning Market of Luang Prabang as a cultural treasure that unites the traditions of eating a large number of living species with very diverse flora and fauna. Measures should be taken to strike a balance between local foraging traditions and nature conservation priorities.
