“…In our investigation, we identified Pb concentrations measuring 0.64 ± 0.14 mg/kg in chilled beef and 0.89 ± 0.21 mg/kg in frozen beef. Various studies have reported Pb concentrations in muscle, liver, and kidney samples of edible tissues from diverse animal species in various countries, ranging between 0.008 and 5.48 mg/kg ( Liu, 2003 ; Sedki et al , 2003 ; Alturiqi and Albedair, 2012 ; Alkmim Filho et al , 2014 ; Bazargani-Gilani et al , 2016 ; Hashemi, 2018 ), the levels observed in our beef samples align with or slightly exceed some of these reported values. In our findings, Cd concentrations were recorded at 0.02 ± 0.14 mg/kg in chilled beef and 0.02 ± 0.004 mg/kg in frozen beef, which are within permissible limits.…”

Background: The consumption of meat is a fundamental aspect of global diets, providing essential nutrients and proteins vital for human nutrition. However, ensuring the safety of meat products has become progressively challenging due to potential contamination by toxic heavy metals and pathogenic microorganisms. Aim: This study focuses on assessing the prevalence of Lead (Pb), Mercury (Hg), Arsenic (As), and Cadmium (Cd), in chilled and frozen meat in Sharkia Governorate, Egypt. Methods: A total of 30 samples, comprising 15 chilled and 15 frozen beef samples, were collected from various marketing stores in Sharkia. Analysis of toxic metals was conducted via atomic absorption spectrophotometer following wet digestion. Results: The average levels (mg/kg) in chilled meat samples were found to be 0.64 ± 0.14 for Pb, undetectable for Hg, 0.02 ± 0.14 for Cd, and 4.66 ± 0.57 for As. In frozen samples, the average concentrations were 0.89 ± 0.21 for Pb, 0.08 ± 0.03 for Hg, 0.02 ± 0.004 Cd, and 5.32 ± 0.59 for As. Generally, the levels of heavy metals in frozen meat samples were observed to be higher than chilled samples. Importantly, the levels of Pb were higher than maximum residual concentrations (MPL) in 53.3% of the chilled and 66.6% of the frozen, Cd levels in chilled and frozen were within the permissible concentrations in all samples, Hg was not identified in all the chilled and in 67% of frozen samples, and As levels were higher than the permissible levels in all samples chilled and frozen. The assessment of human health risk for adults revealed an estimated daily intake (EDI) value of beef meat below the threshold of the oral reference dose (RFD) for all analyzed metals except for As, where 46.7% of chilled samples and 60% of frozen samples exceeded the RFD. Furthermore, both the Hazard Quotient (THQ) for As and Hazard Index (HI) for all the analyzed metals were above 1 in 33.3% of chilled samples and 46.7% of frozen samples. Conclusion: This indicates the remarkable adverse effects on human health associated with the consumption of meat of elevated levels of heavy metals, emphasizing the need for stringent quality control measures within the food industry.

“…Methods for total As determination in meat have been developed in past years and consequently application studies began to be regularly performed in order to increase databases (Joint FAO/WHO Expert Committee on Food Additives (JECFA), ; Bilandžić et al ., ; Blanco‐Penedo et al ., ; Hassan et al ., ; Chen et al ., ; Lei et al ., ; Hwang et al ., ; Wang et al ., ; Alkmim Filho et al ., ; Ghosh et al ., ; Roggeman et al ., ; Bortey‐Sam et al ., ).…”

A nonchromatographic analytical procedure has been developed for the determination of arsenic in meat samples including the major toxic arsenic species arsenite, arsenate, monomethylarsonic acid (MMA) and dimetylarsinic acid (DMA). The method is based on the extraction of arsenic species in mild conditions, selective trivalent hydride formation and final determination by hydride generation atomic fluorescence spectroscopy (HG-AFS). Different extractant agents and two different procedures, microwave-assisted extraction (MAE) and ultrasound assisted extraction at room temperature, were evaluated for As species extraction. The method provided a limit of detection of 0.013 ng mL À1 and a mean relative standard deviation in actual samples of 0.3%. Data found for toxic As in meat samples varied from 0.42 ng g À1 in chicken muscle to 68 ng g À1 in pork liver. Percentage of toxic As respect to total As varied in the 9-46% range depending on the meat product.Determination of toxic arsenic in meat M.

“…Cattle might accidentally absorb lead-containing things from their environment, such as household, industrial, or agricultural trash, due to their natural curiosity, licking tendencies, and indiscriminate feeding habits. This can result in acute lead poisoning [37,43]. Acute lead toxicity in cattle and buffaloes, as well as subclinical toxicity in goats affecting essential trace mineral profiles, was caused by contamination of vegetation and pastures near secondary lead smelters (battery recycling units) and lead-zinc smelters [44,45].…”

Heavy Metals - Recent Advances

Heavy metals are metallic elements with a high density compared to water that are found in trace amounts in a variety of matrices. Mercury poisoning can cause brain damage, skin damage, and increase risk of cancer development. Mercury-poisoned animals cannot produce meat, liver, or kidneys fit for human consumption. Heavy metals can cause cell dysfunction and toxicity by attaching to protein sites and displacing the original metals from their native binding sites. Reducing input/output ratio of heavy metals in animals should be the main objective of effective solutions. Electro-remediation involves running an electric current through liquid manure to cause metal ions to precipitate on an electrode.
