Purpose The purpose of this paper is to investigate the role of perceived food quality and consumer ethnocentrism and potential trade-offs between these two concepts in Russian consumers’ food purchase decisions after the implementation of the Russian import ban. Design/methodology/approach Survey data were collected via in-person interviews in the City of Perm, which is one of the largest and most industrial cities in Russia. A double-bounded dichotomous-choice contingent valuation model is utilized to estimate willingness to pay (WTP) and to analyze factors that affect consumers’ choice. Findings The results suggest that most respondents do not consider domestically produced cheese as a risky product in terms of food safety but simply of lower quality than imported cheese. However, the average respondent’s WTP discount for domestic cheese compared to imported cheese is 8 percent, which is relatively small. This corresponds to participants’ opinion that buying domestic cheese is the right thing to do since it supports Russian farmers and producers. The results indicate further that with increasing education and income levels, individuals are less likely to prefer domestically produced cheese for either economic or quality reasons. This effect is stronger for the quality preference. Research limitations/implications The results indicate that if the Russian government aims at expanding the domestic food market further, more attention needs to be paid to ensuring the quality of domestic food products in order to increase consumer acceptance and WTP. Originality/value This is the first study providing empirical evidence on Russian consumers’ attitudes and perceptions of domestically vs imported food products after the implementation of the Russian import ban, which can be considered as an external policy shock.

Listeria Species

Listeria monocytogenes is an important foodborne pathogen with high mortality. L. monocytogenes and five other Listeria species can frequently be found in the same sample. To identify Listeria isolates found in foods to the species level, two multiplex PCRs were designed. The PCR and conventional biochemical methods were compared for the identification of 456 Listeria isolates collected from routine food quality monitoring schemes between June 2004 and February 2006 and for 62 L. monocytogenes isolates from patients between 1999 and 2005. The results showed that the PCR and biochemical methods had 100% agreement in Listeria identification. The distribution of Listeria species from foods was as follows: L. monocytogenes, 50.4%; L. innocua, 33.8%; L. welshimeri, 14.9%; L. seeligeri, 0.7%; L. grayi, 0.2%; and L. ivanovii, 0.0%. Additional analyses were performed to identify the major serotypes (1/2a, 1/2b, 1/2c, and 4b) and the three lineages of L. monocytogenes isolates from foods and patients, with 1/2a (69.6%) and 1/2b (21.7%) dominating the food isolates and 1/2b (54.8%) and 4b (30.7%) dominating the patient isolates. The lineage results showed that isolates of 1/2a and 1/2c belonged to lineage II and that isolates of 1/2b and 4b belonged to lineage I. The multiplex PCRs for Listeria identification that have been established provide an accurate and rapid method for food quality control. This study has provided the basic knowledge of distribution of Listeria species and L. monocytogenes serotypes in Queensland, Australia, which is useful for epidemiological investigations of listeriosis.

The consumer acceptance of novel enhanced-quality products and their willingness to buy such products may be a crucial topic in the field of marketing. The aim of this study was to analyze the association between consumers’ perceptions of food quality and their acceptance of enhanced meat products and novel packaging. The study was conducted using the Computer-Assisted Personal Interview (CAPI) method in a random group of 1009 respondents, who were recruited as a representative sample based on data from the Polish National Identification Number database. The participants were asked about the most important quality determinants of food products of animal origin and about quality improvement methods and their acceptance of those methods. The quality determinants of animal-based food products were indicated as follows: origin, production technology, manufacturer, components and nutritional value, visual and sensory characteristics, expiry date, and cost. The quality improvement methods were clustered into groups that were associated with product enhancement and application of novel packaging, and the acceptance of those methods was also verified. Indicating specific quality determinants of animal-derived food products affects the consumer acceptance of product enhancement (p = 0.0264) and novel packaging as quality improvement methods (p = 0.0314). The understanding that enhancement is applied for the purpose of quality improvement did not influence the acceptance of products (p = 0.1582), whereas the knowledge that novel packaging is applied influenced the acceptance (p = 0.0044). The obtained results suggested that in the case of application of novel packaging, a higher level of knowledge may be a reason for consumer’s rejection of the resulting products, but the appearance and taste of products may contribute to the higher acceptance of novel packaging. Educating consumers may improve their acceptance of product enhancement, as concerns about the addition of food preservatives may lead them to reject enhanced products.

The exploitation of lipid membranes in biosensors has provided the ability to reconstitute a considerable part of their functionality to detect trace of food toxicants and environmental pollutants. Nanotechnology enabled sensor miniaturization and extended the range of biological moieties that could be immobilized within a lipid bilayer device. This chapter reviews recent progress in biosensor technologies based on lipid membranes suitable for environmental applications and food quality monitoring. Numerous biosensing applications are presented, putting emphasis on novel systems, new sensing techniques and nanotechnology-based transduction schemes. The range of analytes that can be currently detected include, insecticides, pesticides, herbicides, metals, toxins, antibiotics, microorganisms, hormones, dioxins, etc. Technology limitations and future prospects are discussed, focused on the evaluation/ validation and eventually commercialization of the proposed sensors.
