Background: Chlorinated pesticides have been used in pest control for several decades in the world. These compounds are still applied in many regions, and their continuous usage has resulted in their bioaccumulation and residue in the food chain. These residues could transfer to food products and accumulate in fat tissues. Undoubtedly, the breast milk could be a significant biomarker for esti...

A cross-sectional study was conducted to detect the presence of Salmonella spp., Candida albicans, Aspergillus spp., and antimicrobial residues in raw milk (n = 120) and processed cow milk (n = 20) from smallholder dairy farms from three sites in Zimbabwe. Culture and isolation of Salmonella spp., C. albicans, and Aspergillus spp. were performed using selective media, while antimicrobial residu...

Three lactating Holstein cows (634 to 698 kg) were dosed, respectively, with 65.6 mg (44.5 microCi/mg), 131.2 mg (20.1 microCi/mg), or 8.4 mg (141.3 microCi/mg) of [14C]nitrofurazone by intramammary, intrauterine, or topical ocular administration. Intramammary and intrauterine treatments were single doses; ocular treatment was daily for 4 consecutive d (2.1 mg/d). Cows were slaughtered after 72...

Penicillin is one of the most commonly detected drug residues in tissues and milk, and is the antimicrobial for which information is most often sought through FARAD.

Allergies to cow’s milk are very common and can present as life-threatening anaphylaxis. Consequently, food labeling legislation mandates that foods containing milk residues, including casein and/or b-lactoglobulin, provide an indication of such on the product label. Because contamination with either component independent of the other can occur during food manufacturing, effective allergen mana...

The infusion of ozone into the inflamed quarter of cows with clinical mastitis was performed and the efficacy of ozone therapy was evaluated. Ozone was infused into the inflamed quarter via a teat canal using ozone gas generating equipment. Nineteen Holstein cows with acute clinical mastitis were divided into two groups: 15 cows treated with ozone therapy, and 4 cows treated with antibiotic the...

Therapeutic efficacy of mastitis can result in frustrating clinical outcomes, depending on the causative pathogen, the severity and duration of infection, and expectations of the dairy producer. In herds that have controlled contagious mastitis, costs incurred from clinical mastitis likely account for the largest proportion of total herd mastitis costs, and in some instances, a majority of thes...

Antibacterial drugs used in animal might result in deposition of residues in meat, milk and eggs. The presence of antimicrobial residues in animal-originated food is critical problem in many countries over the years. Because, drug residues might result in various health hazards, both actual incidence of reactions and potential hazards perceived by the public, the most countries assess residue o...
