Throughout these past decades, climate change has featured among one of the most complex global issues. Characterized by worldwide alterations in weather patterns, along with a concomitant increase in the temperature of the Earth, climate change will undoubtedly have significant effects on food security and food safety. Climate change engenders climate variability, which are significant variations in weather variables and in their frequency.

Bottled tea beverages (BTB) are popular for the benefits to human health and convenience. Because Chlorpyrifos (CP) is commonly used as a biomarker for exposure as well as a pesticide in the field, it is important to determine the dynamics of CP dissipation in BTB in order to better perform risk assessments.

Edible insects are a novel food in most countries; their popularity is growing because of their high protein/low fat content, ease of cultivation, and small environmental impact. To our knowledge, this is the first report that addresses both microbiological and chemical hazards in edible insects. Samples were collected from retail stores or purchase through e-commerce. A total of 51 samples of dried whole insects or insect powders were tested for generic Escherichia coli ( E.

The aim of the present study was to evaluate the contamination levels of some classes of persistent organic pollutants (POPs) in free-range hen eggs and to estimate the related human dietary exposure in a Site of National Interest (SNI), characterized by a serious state of environmental pollution (Bussi sul Tirino area, central Italy).

The increase in fat-related diseases and chemical hazards produced during the frying process poses a major threat to human health. Coating has been used as a practical method to reduce the oil content and chemical hazard of fried foods. Methyl cellulose (MC) and soy protein isolate (SPI) were used as coating materials to pretreat Chinese fried dough cake (CFDC) before frying.

Aquatic products are favored by people all over the world, but the potential quality and safety issues cannot be ignored. In order to determine the risk of veterinary drug residues in aquatic products in the Yangtze River Delta, this paper used the Geographic Information System (GIS) method to analyze Chinese veterinary drugs in aquatic products in Shanghai, Jiangsu, Zhejiang, and Anhui (Yangtze River Delta Urban Agglomerations) from 2017 to 2019.

Mining is one of the major sources of heavy metals in most developing countries and this has become a major health concern to the populace due to the possibility of food contamination with these heavy metals.

A study was conducted to evaluate the efficacy of seven decontamination processes in reducing the pesticide mixture load of six insecticides (quinalphos, profenophos, ethion, lambda- cyhalothrin, imidacloprid and acetamiprid) from chilli alongwith one control treatment where the pesticide residues were extracted without following any decontamination procedure.

The inhibition kinetics of glutathione (GSH) and quercetin on Acrylamide (AA) formation in the low-moisture Maillard systems were investigated at 180 °C. The inhibition rates in an equal-molar asparagine/glucose (Asn/Glc) system was higher than those in asparagine/fructose (Asn/Fru) system, and the maximum inhibition rates for AA were 57.75% with GSH of 10 -2 mol L -1 and 51.38% with quercetin of 10 -1 mol L -1 .

The occurrence, concentrations and variables associated with tetracycline, polyether ionophore and anthelmintic residues in the livers of chickens sold in the informal market in South Africa were determined. An ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS) was used to simultaneously analyze for four tetracyclines, five polyether ionophores and six anthelmintic residues.
