Norovirus contamination of oysters is the lead cause of non-bacterial gastroenteritis and a significant food safety concern for the oyster industry. Here, norovirus reduction from Pacific oysters (Crassostrea gigas), contaminated in the marine environment, was studied in laboratory depuration trials and in two commercial settings.

ABSTRACT

ABSTRACT Background Fruit and vegetable consumption has increased among masses due to their tremendous health benefits. However, recent studies have shown that contaminated products may serve as a vehicle for foodborne pathogens and harmful chemicals. Therefore, fresh vegetables must be decontaminated before consumption to ensure food safety.

In this study, a practical and excellent method was used to determine the famoxadone and cymoxanil via high-performance liquid chromatography equipped utilizing ultraviolet detector lamp (HPLC-UV) for investigating the dissipation behavior and residue distribution of famoxadone and cymoxanil in cucumber and soil ecosystem. The limit of quantification (LOQS) of famoxadone and cymoxanil in cucumber were 0.50, 1.00, 2.00 and 0.05, 0.50, 1.00 mg kg−1 in soil, respectively.

BACKGROUD To extend the storage time of postharvest cherry tomato, boscalid are often used. Pesticide residue has become an issue of food safety. This study was to investigate the spatial distribution of boscalid residue in cherry tomato fruits and to determine the effect of 24‐epibrassinolide (EBR) in promoting boscalid degradation. RESULTS Boscalid could quickly penetrate into cherry tomatoes, but mainly remained in the peel.

The uncontrolled use of pesticides on leafy vegetables has been frequently reported in recent years. The aim of this study was to evaluate the influence of pH, total acidity and various technological processes for the preparation of babenda on pesticide residues contained in leafy vegetable. The "babenda" is a Burkinabè dish consisting mainly of Hibiscus sabdariffa, Amaranthus hybridus and Cleome gynandra coarsely cut from steamed rice.

Due to high toxicity to mammals and hazard to the ecosystem, parathion has been banned or limited for use in many countries. It is essential to ensure food safety by parathion suspecting. On-site testing, as a critical component of the food chain safe system, plays a major role in the protection of food safety and human health.

Background Pyraclostrobin and picoxystrobin are two representative pesticides of strobilurins used to treat cucumber downy mildew, which have raised issues of food safety and human health. A new formulation containing these two compounds is being prepared for marketing in China.

ABSTRACT BACKGROUND Cyromazine and acetamiprid are widely applied as pesticides in agriculture, causing increasing concerns about their residues in crops. In this study, cyromazine, acetamiprid and their mixture were applied to cowpea to investigate their degradation dynamics and perform a dietary risk assessment.

BACKGROUND Increased awareness of consumers on food safety promotes the development of rapid and sensitive detection techniques for pesticide residues. In this study, a new type of rapid detection card for organophosphorus (OPs) and carbamates (CMs) pesticide residues was developed by electrospinning.
