Safety improvement of the open sun dried Egyptian Siwi dates using closed solar dryer.

Egyptian Siwi dates dried using the open sun drying is exposed to different contaminants. So, the current study aims to use the closed solar dryer to improve Siwi date safety. The impact of washing and closed solar drying on the levels of microbial load, aflatoxins and heavy metals in Egyptian Siwi dates (ESD), in comparison to traditional open sun drying methods were examined.

Potential health risk assessment for heavy metals in Tilapia fish of different spatiotemporal monitoring patterns in Kafr El-Shaikh and El-Faiyum Governorates of Egypt.

Heavy metal (HMs) levels were evaluated in aquacultured tilapia fish collected from two highly producing districts in Egypt (Kafr El-Sheikh and El-Faiyum Governorates) during two seasons (autumn 2021 and spring 2022). As well, health risk assessment of exposure to HMs in tilapia fish was studied. The results revealed that six HMs: As, Cu, Fe, Mn, Cr and Zn were predominant in fish samples of the first season (autumn 2021), while most of HMs were existed in samples of the second season.

Effect of replacing cottonseed meal with canola meal on growth performance, blood metabolites, thyroid function, and ruminal parameters of growing lambs.

The objective was to clarify the impact of replacing cottonseed meal with canola meal (CM) on growth performance, blood metabolites, thyroxin function, and ruminal parameters of growing lambs. Twenty-four growing Barki male lambs (4-5 months of age) were assigned randomly into four equal groups (6 lambs each). Four dietary treatments were the control group with 0% CM (CON) and three experimental groups where CM replaced 25% (CN), 50% (CN), and 75% (CN) of cottonseed meal.

Control of carbendazim toxicity using banana peel powder in rats.

Carbendazim (CBZ) is a steady benzimidazole fungicide broadly exploited in cultivation for pre- and post-harvest treatment to dominate microorganisms infection on several plants. CBZ causes toxic effects in the different tissues of rat via influencing biochemical and hematological factors causing histopathological alterations in the liver and kidney of rats. Banana peel (BP) makes up about 38% of the whole banana weight, BP is usually disposed of as waste that is considered as an environmental problem.
