“…According to Summers et al (1995), this disorder is not commonly described in cattle poisoned by lead; however, it is often reported in dogs poisoned by this element. This result also differs from the findings described by Traverso et al (2004) in cattle poisoned by lead. The histopathology of these previous cases showed neuronal necrosis, cerebrocortical malacia, gliosis and inclusion bodies in the convoluted tubules of the kidneys.…”

“…Lead poisoning is most commonly observed in calves up to six months of age, suggesting that this increased susceptibility of young cattle to lead poisoning is due to increased curiosity and behaviors such as licking foreign objects (Blakley 1984, Gava 2001. The neurological clinical signs presented by the calves, including depression, pushing the head against objects, blindness and death, and the absence of macroscopic findings were similar to cases of lead poisoning in cattle reported by Lemos et al (2004) and Traverso et al (2004).…”

“…Its importance as a toxic metal and environmental pollutant is gaining greater importance and represents a danger to both human and animal health. When lead-containing products are left in pastures or places that animals have access to, such as in waste sites, they can be accidentally consumed and cause intoxication (Traverso et al 2004). Lead poisoning in animals occurs primarily via the oral route, through the ingestion of lead-containing products and the ingestion of pastures and water contaminated by lead (Oskarsson et al 1992).…”

“…Among the animal species susceptible to lead poisoning, cattle are the main subjects of lead intoxication (Traverso et al 2004, Guagnini et al 2005, Marçal 2005); however, sheep (Liu 2003), goats (Gava 2001), horses (Palacios et al 2002), birds (Mazliah et al 1989) and small animals (Morgan 1994) may also experience lead intoxication. In Brazil, there have been several reported cases of lead poisoning in cattle in the state of Paraná, in dairy cows from farms neighboring a metal factory (Marçal 2005); in the state of Rio Grande do Sul, in animals kept in pastures contaminated by spilled contents of paint cans and in animals grazing in military artillery training fields (Traverso et al 2004, Guagnini et al 2005; in the state of Mato Grosso do Sul, in Nellore cattle kept in pastures near a car battery recycling facility (Lemos et al 2004); and in horses in the Vale da Paraíba, São Paulo state, on a farm close to an industrial lead processing and recovery facility (Mazzeo et al 1984).…”

Lead poisoning in cattle and chickens in the state of Pará, Brazil

The present study describes the occurrence of lead poisoning in cattle and chickens in Pará, Brazil. In a lot composed of 80 calves from a dairy herd, 10 animals became sick and nine died, but one animal recovered after being removed from the paddock. Upon inspection of this paddock, the presence of truck batteries used to store energy captured by solar panels was found. The clinical signs observed in calves included difficult breathing, nasal discharge, excessive salivation, corneal opacity, pushing of the head against objects and recumbency. The chickens had decreased oviposition and produced eggs with thin or malformed shells. The necropsy findings of the cattle, as well as the histopathological changes observed, were of little significance except for one animal that showed mild astrocytosis histopathology in the cerebral cortex. In one of the chickens, renal histopathology showed mild multifocal acute tubular necrosis. The mean lead concentrations in the livers and kidneys of the cattle were 93.91mg/kg and 209.76mg/kg, respectively, and the mean concentration detected in chicken livers was 105.02mg/kg. It was concluded that the source of lead poisoning in these calves and chickens were the truck battery plates, which were within reach of the animals.

Determination of Cd, Pb and Se in beef samples using aerosol dilution by ICP-MS

et al. 2021

View full text Add to dashboard Cite

An analytical method for sample preparation and subsequent determination of Cd, Pb and Se in beef using aerosol dilution by inductively coupled plasma-mass spectrometry was developed. The use of high matrix introduction technology allowed the introduction of a complex sample into the plasma with higher content of total dissolved solids a residual acidity of 4% and better tolerance to matrix effects. Trueness was verified by the analysis of two reference materials. At the 95% significance level, results were statistically equivalent to the certified or informed values. Analytical precision expressed as relative standard deviation was less than 9% in all cases. After validation, a total of 12 beef samples from Uruguay were analyzed. Obtained levels for Cd and Pb were far below the maximum limits established by international regulations in all samples. Also, results showed that beef from this region is a good source of Se in the range 0.120-0.870 mg kg −1 with an interesting contribution to the daily intake of this essential element.

The exposure of lead to body can be through inhalation, digestion and adsorption. Lead intoxication can lead to jejuna damages and increase protease activity due to reactive oxygen species (ROS) production. Apple peel extract contains flavonoids that can scavenge ROS. This research aims to investigate the effect of ethanolic extract of Rome Beauty apple peel to protease activity and jejuna histological feature of rat exposed to lead acetate. This research used 20 rats, that divided into 5 treatment groups, which were negative control group (healthy rat), positive control group (exposed to lead acetate 10 mg/rat/day for 14 days), and preventive therapy group (administrated the apple peels extract with doses of 28 mg/200 g BW, 56 mg/200g BW, 112mg/200g BW for 21 days and also lead acetate with 10mg/rat/day for 14 days on day 15th until 28th). Jejunal histological features was stained using HE stain which then observed using a microscope. Protease activity was measured by using spectrophotometric method. The data of protease activity was statistically analyzed using ANOVA, followed by Tukey test (α = 5%). The results showed that the administration of ethanolic extract of Rome Beauty apple peels at best dose of 112 mg/200 g BW can reduce protease activity and improve jejuna histopathology. The conclusion of this study was that apple peels extract of Rome Beauty can be used to prevent the increase of protease activity and the damage of rat jejuna exposed to lead acetate.
