The recovery of nutrients from unconventional water such as domestic sewage is considered as a sustainable solution to environmental sanitation, personal hygiene, water, and food safety issues. Source separation of urine and the sequenced treatment techniques are the promising approaches to recover the resources from this unconventional water. However, in the storage of urine, urea is hydrolyzed under the action of urease, resulting in odor, precipitation and the loss of ammonia, which is a challenge to be overcome in the process of urine recycling. This review collates research related to urine stabilization, and aims to summarize the characteristics and applications of existing urine stabilization methods, such as acidification, alkalization, electrochemistry, inhibitors and etc. Overall, acidification and alkalization have higher dosage requirements and have an attentional impact on the environment; electrochemical technology is suitable for decentralized sanitation facilities, but the inhibition duration is short; inhibitors are the least effective and are usually used to regulate urease activities in soil environment rather than for urine stabilization. Choosing the appropriate approaches of urine stabilization should focus on the overall perspective of urine resource utilization, consider the separation method and recovery form, and combine it with the concentration technology.

Food safety issues caused by pesticide residue have exerted far-reaching impacts on human daily life, yet the available detection methods normally focus on surface residue rather than pesticide penetration to the internal area of foods. Herein, we demonstrated gold nanoparticle (AuNP)-immersed paper imprinting mass spectrometry imaging (MSI) for monitoring pesticide migration behaviors in various fruits and vegetables (i.e., apple, cucumber, pepper, plum, carrot, and strawberry). By manually stamping food tissues onto AuNP-immersed paper, this method affords the spatiotemporal visualization of insecticides and fungicides within fruits and vegetables, avoiding tedious and time-consuming sample preparation. Using the established MSI platform, we can track the migration of insecticides and fungicides into the inner region of foods. The results revealed that both the octanol-water partition coefficient of pesticides and water content of garden stuffs could influence the discrepancy in the migration speed of pesticides into food kernels. Taken together, this nanopaper imprinting MSI is poised to be a powerful tool because of its simplicity, rapidity, and easy operation, offering the potential to facilitate further applications in food analysis. Moreover, new perspectives are given to provide guidelines for the rational design of novel pesticide candidates, reducing the risk of food safety issues caused by pesticide residue.

Purpose – The purpose of this paper is to explore Chinese food safety issues by analysing select incidents within he Chinese agricultural marketing system. Design/methodology/approach – A marketing utility framework is utilized to discuss some of the major food safety incidents in China and potential solutions are explored. Findings – The paper finds that food safety issues arise from problems of asymmetric information which leads to the profit seeking behaviour of agents distorting rather than enhancing the creation of one of the four types or marketing utility (time, form, place and possession). Additionally, structural causes found within the Chinese food marketing system have contributed to the food safety problems. Research limitations/implications – This is not an empirical research with numerical data. Originality/value – This study is one of the first to address Chinese food safety problems from an agricultural marketing utility perspective. Key anecdotes are used to support the claims made in this study.

Phytosanitary Measures

With the formation of the World Trade Organization (WTO) in 1995, specific principles and rules were conceived. These rules, or Sanitary & Phytosanitary Measures (e.g., SPS Agreement), relate to three primary issues or concerns: food safety, animal health, and plant health. While still controversial, the WTO/SPS Agreement does provide for more detailed control of food safety concerns and for more standardization and harmonization regarding rules and regulations. This document is FSHN034, one of a series of the Food Science and Human Nutrition Department, Florida Cooperative Extension Service, IFAS, University of Florida.
