Consumers need to obtain this information from producers or social networks, trust in the information,and consequently assess perceived risks, especially when food scandals are exposed to the media. In this study, we introduce the social embeddedness theory to understand how consumers’ social activities affect their risk perceptions on traceable food. Specifically, we investigate how risk perceptions are predicted by the interpersonal relationships, organizational level and social-level relationships. Results show that the interpersonal relationships were associated with lower levels of risk perceptions, while organizational and social relationships impacted consumer’s risk perceptions at middle and higher levels,respectively. Results also show that the "ripple effect" extended to effect of risk events with negative information, however,did not exist for the group exposed to positive information. Potential food safety implications have been proposed to identify for effective risk mitigation under media coverages.展开更多

On the basis of literature research,this paper designs the corresponding questionnaire for empirical analysis. With the college students as the object of study,this paper explores the differences in perceived genetically modified food risk by the college students with different majors,as well as the differences in the information processing mode adopted by the college students with different majors,and the differences in the perceived risk after adopting different information processing mode. The results show that there are significant differences in the perceived genetically modified food risk among the college students with different majors,the economics students have the highest average perceived risk; there are also significant differences in the information processing mode adopted by the college students with different majors,and the perceived risk is different when using the heuristic information processing mode.展开更多

Methods Twenty species were collected from the Zhoushan Archipelago, China. Concentrations of n-3 long-chain polyunsaturated fatty acids, methyl mercury （MeHg）, and dioxin-like compounds （DLCs） in the samples were analyzed for benefit risk assessment based on BRAFO-tiered approach. Results Based on the BRAFO-tiered approach, reference scenario （no intake） and alternative scenario （intake of specific species of 200 g/week） were determined. The exposure to MeHg/DLCs via alternative scenario of all studied species did not exceed provisional tolerable weekly/monthly intake. However, the adult population with high DLCs exposure in China would significantly exceed the upper limit of DLCs via an additional alternative scenario of some species such as Auxis thazard. The results of deterministic computation showed that alternative scenario of all studied species generated clear net beneficial effects on death prevention and child IQ gain. Conclusion The alternative scenario of all studied species could be recommended to population with average DLCs exposure, and the reference scenario of species with relatively high DLCs concentration could be recommended to population exposed to high DLCs.展开更多

Sulfites as food additives are overused or abused in many food categories. When the MPL in GB 2760-2011 was used as sulfites content in food, the intake of sulfites in most surveyed populations was lower than the acceptable daily intake （ADI）. Excess intake of sulfites was found in all the surveyed groups when a high percentile of sulfites in food was intaken. Moreover, children aged 1-6 years are at a high risk to intake excess sulfites. The primary cause for the excess intake of sulfites in Chinese people is the overuse and abuse of sulfites by the food industry. The current MPL of sulfites in GB 2760-2011 protects the health of most populations.展开更多

Food pattern was observed and blood pressure was measured with an automatic electronic sphygromanometer. The diet in Guangzhou seems more refined, fresher and offers more variety than that in the other areas in China. Both systolic and diastolic blood pressure have risen in the period of socioeco-nomic development. Food intake habits are changing in Guangdong, China, with a trend toward an unhealthy diet which increases the risk of cardiovascular disease.展开更多

Evaluating ecological and human health risks of heavy metals levels in sampled food crops harvested near two abandoned Lead-Zinc mining sites at Logo Benue State is crucial. <i>Abelmoschus esculentus</i>, <i>Carica papaya</i>, <i>Manihot esculenta</i>, and <i>Zea mays</i> were sampled, prepared, and analyzed for four heavy metals using the Atomic Absorption Spectrophotometric method. The mean data from the analysis of variance was subjected to ecological and health risk models. Pb means value ranged from <i>Carica papaya</i> Peel 0.46 ± 0.011 mg/kg to 1.30 ± 0.01 mg/kg in <i>Zea mays</i> seed. Zn was highest in <i>Carica papaya</i> flesh 0.50 ± 0.01 mg/kg, and lowest in <i>Manihot esculenta</i> peels and its flesh 0.12 ± 0.000 mg/kg. Hg and Cd were below detectable levels. <i>Zea mays</i> <i>seeds</i> (1.001) had the highest Pd bioaccumulation factor. BAF of zinc and ecological indices were <1. Daily Intake of Metals were all <1, however, Hazard Quotient (HQ) of Pb was ≥1 in <i>Manihot esculenta</i> flesh 1.143 and Zea mays at 1714. Cancer Risks were within permissible range (10<sup>-4</sup> - 10<sup>-6</sup>). Health Risk result indicates communities around the mining area may be at risk of lead poisoning therefore due to high contamination of samples, routine checks on heavy metals especially lead is recommended to prevent excessive bioaccumulation in the body.展开更多

Dietary intake of PAHs for 2862 participants was subsequently estimated by a survey in Taiyuan. Results from these 24 samples were compared with a raw food study in Taiyuan in 2008. Three main sources of dietary PAHs are vegetables, wheat flour and fruits, the sum of which contributes 75.95% of PAHs in dietary food. Compared to the estimated value in raw food, much more B[a]Peq （benzo[a]pyrene equivalents） were detected in food samples collected in the duplicate-diet study in Taiyuan （60.75 ng/day）. The cooking process may introduce more B[a]Peq into food, and the relative contribution of 16 PAHs in the diet would be changed during the cooking procedure.展开更多

In this context, food safety can become a greater concern for a variety of reasons. The purpose of this article is to review the international experiences and lessons regarding food safety management, regulation, and consumer behavior, with the goal of identifying how to improve food safety in middle income countries such as China. International experience in addressing food safety provides two general kinds of lessons. First, a middle-income country such as China needs to develop the capacity to carry out risk analysis in order to better focus public resources on the most important risks. Second, it will be important to leverage market incentives so as to make the best use of limited public capacity to enforce standards. Inter- national experiences show that food safety management is feasible where market incentives exist, and that public-private partnerships can support the process of improving food safety management. Market incentives require effective consumer or buyer demand, mechanisms to identify and reward quality, and supply chain coordination. Public efforts can be targeted to supporting these market developments for the risks that are the greatest burden to public health.展开更多

Then taking organic milk as an example,the factors affecting the customers' buy willingness to pay for organic milk were analyzed by binary logit model and the willingness to pay was also calculated. The results show that the consumers' food safety risk perception degree is high,and the awareness about organic food is low. The consumers' age,level of education,whether the family has children below 12 years old,whether the family has a man( woman) older than 60years,health situation self-evaluation,organic food cognition and food safety risk perception have significant effect on customers' willingness to pay organic food. According to the calculation,the consumers were willing to pay a price premium of 60% for organic milk above ordinary milk.展开更多
