“…The incidence of antibiotic leftover in food of animal origin above the maximum residue limits (MRLs) is considered globally by different public health authorities as being illegal (13)(14)(15). Consequently, persistence of antibiotic residues in food of animal origin have been studied by different researchers in numerous countries (7,(16)(17)(18)(19)(20)(21)(22)(23)(24). The consumption of red meat containing antibiotic residues could lead to direct toxicity, hypersensitivity; which characterized by extent of reactions ranging from mild skin rashes to lifethreatening anaphylaxis, disturbance of the normal GIT microbiota, bone marrow desolation, teratogenic and mutagenesis effects.…”

The incidence of antibiotic residues in meat is considered a serious hazard to public health. This work was conducted to survey the incidence of antibiotics residues among lambs' meats and mutton in Erbil city. The effect of thermal processing on residues was also addressed. From July to December 2018, a total of 280 samples were collected from butcher shops in Erbil city and analyzed microbiologically in plates pre-inoculated with Bacillus subtilis by direct and extraction methods. The overall incidence of antibiotics residues was 10.4% and 13.2% according to direct and extraction methods respectively. The highest incidence rate was detected in December 22.2%. We found that thermal processing, cooking for 45 minutes leads to the conversion of antibiotic residues into completely inactive residues against the bactericidal bacteria. In conclusion, the presence of antibiotic residue among sheep meats in the city of Erbil is high and their persistence is easily eliminated by cooking

“…A low level of dieldrin was reported by Darko and Acquaah (2008) in cow’s milk in Ghana was 1.32 ng/g. A higher level was reported by Nasef et al (2019) , who found that dieldrin was detected in 10% and 6.66% of examined raw milk with a mean value of 147 and 163 ng/g, respectively, in distract “A” and “B” in Alexandria city. In Giza, Egypt, a study by Ahmed and Zaki (2009) indicated that the prevalence of dieldrin in raw milk was 55.5%, with a mean value of 2,966 ng/g.…”

“…The lower level of DDT in raw milk was recorded by Sharma et al (2007) in bovine milk collected from India was 36.7 ng/g with an incidence of 97%; Darko and Acquaah (2008) in cow’s milk in Ghana was 12.53 ng/g; Ismail and Elkassas (2016) in buffalo milk in Egypt was 22.6 ng/g. At the same time, a higher level was reported by Nasef et al (2019) in raw milk collected from three districts (A–C) in Alexandria provinces 217, 251, and 306 ng/g with lower incidence rates of 10%, 6.66%, and 10%, respectively.…”

“…OC pesticides, especially dichlorodiphenyltrichloroethane (DDT) and hexachlorocyclohexane (HCHs), together with the cyclodienes such as aldrin, dieldrin, chlordane, and heptachlor were found in milk and dairy products during the last decades, and they were mentioned in different studies ( Tsiplakou et al , 2010 ; Aslam et al , 2013 ; Nasef et al , 2019 ). DDT was one of the most widely used organochloride pesticides because it could kill various insects, was inexpensive to produce, and had no odor ( Lallas, 2001 ).…”

Background: For decades, the use of organochlorine (OC) pesticides has had a detrimental effect on the environment and human health. Contamination of soil, water, and air has also resulted in contaminated milk. Aim: The purpose of this study was to investigate if any OC residues dichlorodiphenyltrichloroethane (DDT, Dieldrin, Endrin, and Lindane) were present in raw bovine milk from West Delta, Egypt. Methods: 200 fresh raw cow milk samples (500 ml of each sample) collected from three different governorates, west Delta, Egypt, for determination of OC pesticides residues using gas chromatography with an Agilent 6890A model gas chromatograph equipped with a 63Ni microelectron capture detector. Results: The obtained results revealed that åDDT, dieldrin, endrin, and lindane were detected in Alexandria, Behera, and Matrouh at incidence levels (22.7%, 30.7%, and 10%), (20%, 20%, and 16%), (9.33%, 13.3%, and 16%), and (12%, 10.7%, and 14%) with mean values of 232.2 ± 163.6, 156.4 ± 134.6 and 100.4 ± 85.9; 91.3 ± 61.2, 95.3 ± 59.8 and 57.6 ± 3.33; 15.7± 3.86, 15.1 ± 3.96 and 20.1 ± 7.33; 33.7 ± 10.6, 36.9 ± 5.51 and 52.2 ± 21.8 ng/g fat, respectively. El-Behera was the most contaminated province with an incidence level of 53.3% with a mean value of 136.8 ± 128.0 ng/g fat, followed by Alexandria at 44% with a mean value of 173.7 ± 155.5 ng/g fat, and finally, Matrouh 40% with a mean value of 74.5 ± 56.5 ng/g fat. Conclusion: This research demonstrated that milk samples contain varying levels of OC pesticide residues, which can be hazardous to consumer health. Therefore, to safeguard consumers, especially children, and the elderly, OC pesticide residues in milk must be closely monitored.

“…Milk is an ideal fluid for dissolving environmental organic pollutants such as pesticide residues because most of them have lipophilic properties. Thus, milk is used as an indicator for determining the persistence of organic pollutants 12 . Their presence in dairy products occurs mostly due to the feeding of contaminated fodder, feedstuff and water to dairy cattle 13 .…”

The aim of this study was to investigate and trace the biodegradation products of the pesticide malathion in a comparative manner by two different lactobacilli strains; L. casei (NRRL1922) and L. acidophilus (NRRL 23431). The two strains were cultivated separately into skimmed milk supplemented with 5 ng/ml malathion. After incubation under the appropriate conditions, randomized samples were taken at intervals 24, 48, 72 and 120 hours along with control samples and analyzed for the presence of malathion and its degradation products by the GC-MS spectrometry; As well as, analyzed to record the level of phosphatase enzyme which suggested to be involved in the biodegradation process. The results showed a high ability of the two tested strains to degrade malathion with a superiority of L. acidophilus (NRRL 23431) over L. casei (NRRL 1922). The level of phosphatase enzyme was elevated in both strains in the presence of malathion and decreased gradually upon the depletion of malathion from the sample, which reflects the role of the phosphatase enzyme in the biodegradation process.
