Food safety is about everyone’s health. Through risk assessment and early warning of food safety, food-related safety issues can be identified as early as possible and take timely precautions. However, the detection data of food safety are complex and non-linear, so it is necessary to find the relationship and hierarchical representation of factors affecting food safety. This paper presents an improved entropy weight based on Hasse diagram technology (HDT) method to analyze the influencing factors of food safety. The entropy weight method was used to calculate the weight of each factor index, and the relationship matrix was obtained. Then, the data of infant milk powder in China were analyzed hierarchically by the HDT method. Thus, we can obtain the multi-level structure that affects food safety. It provides an effective basis for early warning of food safety, can help government regulators to strengthen management, and urge enterprises to produce food safely.

AbstractWe surveyed shoppers at a food cooperative in New York state to measure the relationship between organic produce purchases and attitudes related to pesticide use in agriculture, food costs, and other factors affecting produce buying. Two-fifths of the co-op shoppers surveyed usually or almost always purchased organically grown produce, and one-third were somewhat or very likely to pay 100 percent more than conventional produce for residue-free produce. Those who usually or almost always purchased organic produce were less concerned than other shoppers about price when they shop for produce, had higher levels of concern about food safety, and were less concerned about insects and surface blemishes on produce. There was no relationship between income and frequency of organic purchases. Most shoppers were concerned about pesticide residues in produce, but a high level of concern appeared necessary to affect the frequency of organic purchases. In their support of organic agriculture, respondents ranked environmental protection higher than consumer protection. Educators should emphasize both the environmental and food safety benefits of organic farming to consumers.

Suffolk Sheep

At a time of high public awareness of food safety issues, particularly with respect to transmissable encephalopathies, and a government policy to eradicate scrapie, there is increasing pressure for breeders to select for scrapie resistance in sheep. Genetic variation has been identified at the PrP locus that confers differing degrees of susceptibility to scrapie. In the Suffolk breed this variation is confined to amino acid variations at codon 171, resulting in two alleles R and Q. Animals with the genotype RR and RQ show a greater degree of resistance to scrapie than animals with genotype QQ (Hunter, Moore, Hosie, Dingwall and Greig, 1997).Genotyping of pedigree animals has now become routine for many breeders and RR animals are favoured. It is, however, unknown whether there is a relationship between PrP genotype and performance traits. The objective of this study was to analyse the relationship between PrP genotype at codon 171 and the performance traits included in the Lean Index (Simm and Dingwall, 1989), which is used for selection in the Suffolk breed.

Emotion Type

Social media is gradually building an online information environment regarding health. This environment is filled with many types of users’ emotions regarding food safety, especially negative emotions that can easily cause panic or anger among the population. However, the mechanisms of how it affects users’ emotions have not been fully studied. Therefore, from the perspective of communication and social psychology, this study uses the content analysis method to analyze factors affecting social media users’ emotions regarding food safety issues. In total, 371 tweet samples of genetically modified food security in Sina Weibo (similar to Twitter) were encoded, measured, and analyzed. The major findings are as follows: (1) Tweet account type, tweet topic, and emotion object were all significantly related to emotion type. Tweet depth and objectivity were both positively affected by emotion type, and objectivity had a greater impact. (2) Account type, tweet topic, and emotion object were all significantly related to emotion intensity. When the depths were the same, emotion intensity became stronger with the decrease in objectivity. (3) Account type, tweet topic, emotion object, and emotion type were all significantly related to a user’s emotion communication capacity. Tweet depth, objectivity, and user’s emotion intensity were positively correlated with emotion communication capacity. Positive emotions had stronger communication capacities than negative ones, which is not consistent with previous studies. These findings help us to understand both theoretically and practically the changes and dissemination of user’s emotions in a food safety and health information environment.

PurposeThis study aims to focus on the food industry and empirically examine the mediating role of consumers’ perceived food safety on the relationship between a company’s service recovery and customer loyalty. In addition, consumers’ demographic characteristics and their influences on the relationship between perceived food safety and customer loyalty are determined.Design/methodology/approachA survey was carried out through a structured questionnaire which was administered to the public. Using a small intercept interview, a random sample of 836 usable questionnaires was collected in Greece. Exploratory and confirmatory factor analyses were applied to validate the proposed constructs. The causal relationships among constructs were examined using structural equation modeling.FindingsAccording to the findings, consumers’ perceived food safety partially mediates the effect of a company’s service recovery on customer loyalty. The socio-demographic profile of consumers (gender, marital and parenthood status) also significantly influences the underlying factors of product and the loyalty attributes.Practical implicationsThis study enriches the existing literature of food safety by examining the distinct role that consumers’ perceptions play in forming loyalty, highlighting the importance of companies’ recovery efforts. The results obtained from this analysis offer a better understanding of consumer behavior toward food safety – encouraging and supporting food companies to successfully design their marketing strategies. Food safety issues also have become increasingly important in international trade, which makes it essential to understand consumer perceptions and behavior toward food safety.Originality/valueThis study fills the identified literature gap and contributes to the literature, as no previous study has examined the proposed relationships in the food sector, taking into consideration food safety issues.

Gut Microbiota Composition

Ensuring microbial food safety has always been a challenge at every stages along the food chain. Meanwhile, healthier community lifestyle demands natural antimicrobial agents to alleviate the increasing use of chemical preservatives to address microbial contamination. Antimicrobial resistance issue has also elevated the effort to search for an alternative way to antibiotics. Bacteriophage (phage) is currently being assessed for its potency as biocontrol agent to enhance food safety and as a tool for therapeutic purpose. Prior to phage application, safety assessment must be conducted in which includes several considerations: from the discovery, toxicological aspects to the impact of phage ingestion on the gut microbiota. The gut microbiota which consist of variety of microorganisms inside the human gastrointestinal tract, cohabitate to each other. Phage is naturally present as one of microorganisms in the human gut and dynamically interacted with other microbial communities. Phage application to foods and food-contact surfaces may leave a residue and cause the phages to be ingested, which in result may alter the gut microbiota composition. Many findings have examined the relationship between gut microbiota and human health, and so is the factors affecting their modulation. This review aimed to discuss several points of view from published research papers related to the challenge of phage administration into the human gut.

Macroeconomic Indicator

Subject. The working time of workers at any stage of economic development is a value reflecting the level of labor productivity. Any progress in productivity contributes to changes in the volume of labor costs and the number of employed. Depending on the relationship between the total volume of labor costs and the number of employed, the duration of working time per one worker may change (it may increase, decrease, or remain unchanged). Objectives. The study aims to confirm the importance of such a macroeconomic indicator as the number of employed in varying working hours. Methods. The study rests on the comparative analysis of countries with developed economies based on some indicators like dynamics of the working time fund, dynamics of the number of employed, average number of hours worked during the year per employee, etc. The analyzed timespan is 25 years (from 1991 to 2016). Results. The comparative analysis revealed that in the non-production sphere and the economy as a whole the macroeconomic determinants correlate so that the length of working time per worker reduces. When considering the analysis results for the manufacturing sector, no single trend was identified. Conclusions. One of the key factors affecting the change in working hours is the number of employed. The relationship between the working time fund and the number of employed directly determines the dynamics of working time per worker.
