This study evaluated and revealed the consumption hazards of cattle liver infected with Fasciola spp. and revealed its effects on the serum estimation of liver enzyme (ALT) on experimental rats. A total of42 Wister albino rats were classified into 7 groups. Four groups were fed on raw and cooked cattle liver with various intensity of Fasciola spp. infection. Two groups were fed on raw and cooked normal cattle liver (positive control), and one group served as negative control. Histopathology of the rats' liver revealed hydropic degeneration, congestion with dilatation of the central vein and sinusoids and focal areas of necrosis. The intestine samples showed degenerative changes and necrobiosis of the villar epithelium with inflammatory cell infiltration. Moreover, a slight increase was noticed in the liver enzyme ALT which is known to be an important marker of liver destruction.

The residual concentration of pesticides and heavy metals (arsenic, mercury, selenium, lead, cadmium, and aluminum) was measured in the soil and the cattle egret (Bubulcus ibis) liver from two localities at Sharkia Governorate, Egypt. The pesticide residues have taken the following pattern: chlorpyrifos > metalaxyl > piperonyl butoxide > thiophanate-methyl, in the soil. The residual concentration of pesticides was greater in the soil at Kafr El-Ashraf village (agricultural site) than at El-Qanayat city (garbage site) during the summer season of 2021 compared with the winter season of 2022.

Mass ivermectin (IVM) treatment of livestock (MITL) is under consideration as a malaria control tool as IVM-treated livestock are lethal to blood-feeding Anopheles mosquitoes. MITL is routinely used as a prophylaxis in livestock to reduce the burden and transmission of helminth infections. Recently, there has been a shift in the veterinary IVM market in Southeast Asia wherein nearly all standard IVM formulations are now co-formulated with clorsulon (CLO).
