“…15,17 Levels of various trace metals, including copper (Cu), nickel (Ni), lead (Pb), iron (Fe), manganese (Mn), chromium (Cr), and cadmium (Cd) were determined in commercially available pet foods in Turkey, and found to be within acceptable limits. 7 Nitrates and nitrites are routinely added during the meat curing process for canned products to enhance flavor and color and to prevent spoilage and the growth of toxigenic microorganisms, especially Clostridium botulinum. 4 There have been several reports of mycotoxin outbreaks in pets resulting from the consumption of contaminated commercial foods.…”

An investigation of selected chemical contaminants in commercial pet foods in Egypt

Abstract. Our study aimed to identify the levels of various contaminants in both wet and dry commercial pet foods in Egypt. A total of 20 local and imported pet food products (3 samples each) were screened for heavy metals by atomic absorption spectroscopy, for mycotoxins by enzyme-linked immunosorbent assay, and for nitrate and nitrite levels by nitrate-nitrite spectrophotometry. Cat food, on average, had greater concentrations of the metals cadmium, chromium, lead, and tin than dog food. Of the investigated metals, only tin concentration exceeded the safe level compared with the standards of the National Research Council and the European Commission for the dog and cat. According to the guidelines of the Association of American Feed Control Officials for canned pet foods, the nitrate and nitrite contents of examined foods greatly exceeded the recommended level. No total aflatoxins were detected in the surveyed samples. None of the samples analyzed had levels above international limits established by the Food and Agriculture Organization (FAO) of the United Nations for ochratoxin, and only 1 sample exceeded the level for aflatoxin B1. Of the 20 samples analyzed for zearalenone, 4 samples had higher levels than the FAO maximum tolerable levels. These results indicate that pet foods marketed in Egypt, especially cat foods, occasionally contain contaminants that could result in adverse effects in pets.

“…7 One gram of the sample was transferred to a clean screw-capped glass bottle and digested with 8 mL of digesting solution (65% HNO 3 and 30% H 2 O 2 , 3:1). The mixture was heated to 150°C until complete solubilization, which was followed by the addition of 5 mL of distilled water to each sample and remixing.…”

“…As previously demonstrated, some commercially available dry foods for cats and dogs tend to have a lowered Fe content compared to corresponding wet products (Duran 2010). Importantly, the bioavailability of Fe in pet food is often low, particularly in forms of oxide or carbonate (NRC 2006).…”

Iron (Fe) represents a highly essential element for various biological processes. In spite of this very little is known as regards its status in mammalian reproductive tissues and factors that may potentially influence it. At the same time, there is an ongoing debate as to whether analyses of the Fe content in hair can provide reliable information on its tissue burden. Therefore, the aim of the present study was to investigate the content of Fe in the testicular and uterine tissues, and hair of the domestic cat (Felis catus) and how this content relates to an animal's age, weight, physical activity, inhabited environment and diet. The median Fe content in the feline reproductive tissues amounted to 50.8 ppm and in hair to 180.2 ppm. As found, free-ranging cats were characterized by a significantly higher Fe content in reproductive tissues, particularly in the uterus. Age, weight and physical activity had no effect on determined Fe levels. The type of commercial diet (wet, dry or combined) given to household cats also had no influence upon Fe status in hair and tissue although males fed exclusively on dry food had a lower Fe testis :Fe hair ratio. Hair Fe level was positively correlated with that found in the reproductive tissues (Rs=0.30). This study extends the body of information on Fe distribution in felines, demonstrates the difference between free-ranging and household cats and provides evidence that Fe hair status may, at least partially, reflect the status of this element in the feline reproductive system.

“…The accurate and sensitive determinations of trace elements are the important part of analytical chemistry studies. [2][3][4] Flame atomic absorption spectrometry (FAAS) is relatively simple and available technique in many laboratories for heavy metal determination. [5][6][7][8][9][10] Because of the large amount of organic substances in the samples, digestion or ashing is required prior to analysis and the low concentrations of the measured elements demand well-organized [11].…”

In this work, Flame Atomic Absorption Spectrometry (FAAS) was applied for the determination of Cu, Fe, Mg, Mn, Ni, and Zn in twenty -four hair samples. The samples were collected covering different ages and gender. The samples are divided as, seventeen samples from people which assumed to be environmentally healthy (control) and seven samples from different worker's people such as Iron worker, Cement worker and Duco worker (exposed). Samples were brought into solution using HNO 3 and H 2 O 2 . In three example samples the molecular structure of the human hair was studied using Fourier Transformer Infrared Spectrometer (FTIR) in the range of 200-4000 cm -1 .The contamination of the sample was discussed for different samples.
