Abstract Existing cleaning methods mainly focus on removing free‐state pesticides. However, mancozeb can bind to the wax layer of grapes, forming bound‐state residues that are difficult to remove. This study aims to develop an effective cleaning strategy to eliminate both free and bound mancozeb residues from grapes.

Various regulatory frameworks and multi‐residue screening methods reviewed since 2010 have been implemented to ensure consumer safety by controlling antimicrobial residues in milk. Antimicrobial residues in milk pose a significant risk to human health, prompting regulatory bodies to establish safety limits to protect consumers.

ABSTRACT To address the challenges posed by chemical methods for detecting pesticide residues in sorghum, such as complicated sample preparation and prolonged detection periods, this study presents a rapid and nondestructive detection approach based on hyperspectral imaging (HSI) technology. A group of sorghum without pesticide residues and three groups uniformly sprayed with pesticides were used in this study.

The Vaal River catchment drains the largest and most populated industrial and mining region in Southern Africa. Heron, ibis, cormorant, egrets, and darter eggs, representing three habitats and four feeding guilds, were collected at four locations in 2009/10 to identify hotspots and hazards associated with persistent organic pollutants (POPs).

Apple polyphenols (APs) have gained attention for their various bioactivities, while no studies on anti-liver fibrosis activity are reported. This study evaluated the protective effect of APs on liver fibrosis using LPS-treated activated HSC-T6 cells and alcohol-treated liver fibrosis (ALF) mice.

In swine production, using feed antibiotics as antimicrobial growth promotants has been reduced; thus, feed alternatives to manage gut health are required. Dietary fiber and similar carbohydrate structures such as resistant starch, oligosaccharides, and exopolysaccharides are nutritional tools that may enhance gut health in pigs.

Composting is a viable disposal option for livestock-mortalities and offal; however, is illegal in California due to the perceived risk of disease transfer, heavy metal and nutrient leaching into ground water. Objectives were to determine heavy metal and nutrient concentration in non- and livestock-mortality compost.

Abstract The article explores the science and practice of electrospinning, tracing its history and examining the factors that influence fiber morphology, including the solution composition, processing conditions, and environmental conditions. It offers a thorough examination of electrospinning fundamentals geared toward generating an appropriate platform for creating tailored nanofibers for sensing applications in the food industry.

Oyster shell has been studied as effective stabilizer for heavy metals that exist as cationic forms in soil-aqueous system, but its stabilization capacity for arsenic was very low because of its anionic existence forms. Layered double hydroxide (LDH) shows excellent oxyanion As fixation capacity in soil because of interlayer anion (or complex) exchange, but has relatively low fixation capabilities for other heavy metals.

Overview of metal study in rice. Summary Metal contamination in rice grains is a critical global issue, posing serious health risks and affecting food safety, especially in countries like Malaysia where rice is a staple food. This study aimed to assess the effectiveness of various cooking treatments, with a focus on parboiling before absorption cooking (PBA), in reducing metal contamination in Malaysian rice.

Background The AnticFast® Beta-lactams & Tetracyclines Combo Test Kit is a qualitative two-step (2 min + 5 min) rapid lateral flow assay to detect β-lactam (penicillins and cefalosporins) and tetracycline antibiotic residues in raw commingled cows’ milk.

The use of antibiotics in the livestock care can influence the starter culture activity. In particular, these compounds (β‐lactams and sulfonamides) did not affect the development of Streptococcus thermophilus and Lactobacillus helveticus but hampered the Lb. delbrueckii subsp. bulgaricus acidifying activity also after the withdrawal period. The antibiotic administration in dairy livestock is a current widespread practice.

Various chemicals present at different stages in the food supply chain can lead to the leaching of heavy metals. These metals can accumulate in the human body through the consumption of contaminated food. Consequently, it is necessary to validate an analytical technique for the quantification chemical that could contaminate food.

Bagega community is an artisanal mining community with a history of Pb poisoning. The community is served by a small lake as an important source of water for cattle watering, irrigation, washing, and fishing among other uses. The concentration of Cd, Cr, and Pb in soil and plants at the bank, surface water, sediment, and fish of the lake were analysed using Agilent 4210 MP-AES machine after microwave digestion using the Advanced Microwave Digestion System model (Ethos easy).
