“…Findings related to Ras cheese were in agreement with Amer and Ibrahim [35] and Aiad and Abo Ei-Makarem [11] who found that the mean AFM 1 value in the examined Ras cheese was 56.048±6.29 ng/kg; while higher than Hosny et al [37], Ahmed et al [22], and Younis et al [38] who reported that the examined samples of Ras cheese were contaminated with AFM 1 with a mean value of 15 ng/kg. The results were lower than those cited by Nassib et al [39] and Abdel All et al [40].…”

Background and Aim: Aflatoxin M1 (AFM1) is a major fungal metabolite found in milk coming from aflatoxin B1 (AFB1) contaminated rations and is subsequently present in milk-based products demonstrating a serious public health hazard. This study aimed to investigate the levels of AFM1 and AFB1 in milk and some dairy products consumed widely by infants and children. Materials and Methods: This study investigated the incidence of AFM1 in 105 samples of processed cheese, Ras cheese, and raw milk (35 of each) retailed in the Egyptian markets. The degree of sensitivity and accuracy was evaluated using the enzyme-linked immunosorbent assay (ELISA) method followed by the estimation of the positive samples using the high-performance liquid chromatography (HPLC) with fluorescence detection. Mold count was determined in the examined samples by investigating AFB1 content using HPLC. Results: AFM1 was found in all investigated Ras cheese, raw milk, and 82.86% of the processed cheese samples with mean values of 51.05±6.19, 40.27±3.996, and 10.77±1.39 ng/kg, respectively. Moreover, there was statistically no significant difference between AFM1 levels in the core and crust parts of the tested Ras cheese. AFM1 contaminated Ras cheese and raw milk samples were 48.57% and 25.71%, which exceeded the European and Egyptian tolerance levels. Results showed an acceptable correlation between ELISA and HPLC methods with no significant difference (p>0.05). Alternatively, none of the examined samples proved to be contaminated with AFB1 despite the presence of mold with mean counts of 3.79±3.29, 4.39±4.34, and 4.84±4.29 log CFU/g in the examined processed cheese, Ras cheese, and raw milk samples, respectively. Conclusion: Therefore, it is urgent to regularly inspect the contamination of animal feeds with AFB1 and apply special measures and novel techniques to protect the feed and food from public health hazards.

“…Of these samples, 5 (33.3%) exceeded the Egyptian regulation limit for AFM1 (0 ng/L) while only 2 (13.3%) samples exceeded the European Commission regulation (50 ng/L) ( Table 2). Lower findings were obtained by Aiad and Aboelmakarem [16] while higher result by Hosny et al [17]. The present study revealed the contamination of the examined samples with AFM1 in milk and dairy products thus posing a potential risk to human health.…”

“…All the positive samples exceeded the Egyption regulation limit, while, 2 (13.3%) samples exceeded the European Commission regulation (Tables 1, 2). Higher result was reported by Hosny et al [17]. In another investigations, AFM1 was detected in cheese with the values 64, 64.8, 78 and 80% [22][23][24][25].…”

Aflatoxins (AFs) are toxic and carcinogenic metabolites produced by a variety of fungi. Aflatoxin M1 (AFM1) is the major carcinogenic type frequently found in milk and dairy products, thus posing a significant impact on human health. The current study was undertaken to examine milk and some dairy products for contamination with AFM1 in local markets, Sharkia Governorate, Egypt, as well as the effect of manufacture. A total of 75 samples (15, each) of raw milk, pasteurized milk, yoghurt, processed cheese and Domiati cheese were randomly collected. AFM1 was detected in 27 (36%) out of the examined samples in which the level of AFM1 exceeded the limits (0 ng/L, kg) allowed by Egyptian regulation but only 6 (8%) samples exceeded the limits (50 ng/L, kg) allowed by European Commission regulation. Levels of AFM1 contamination in the examined milk and dairy products with mean values of 35.68 ± 10.90, 45.83 ± 7.80, 7.57 ± 1.92, 24.53 ± 3.91 and 42 ± 4.93 ng/L, kg in raw milk, pasteurized milk, yoghurt, processed cheese and Domiati cheese, respectively, were detected. The level of AFM1 decreased after yoghurt manufactur, while, cheese manufacture showed concentration of AFM1in curd than those in cheese milk. During refrigeration storage of yoghurt, the mean AFM1 toxin decreased after one, two, three, seven days, respectively, then nearly similar level from seven days to fourteen days of storage. In conclusion, widespread presence of AFM1 in raw milk and some dairy products were considered to be possible hazards for public health especially children therefore, continuous monitoring of AFM1 level in commonly marketed raw milk and dairy products in Sharkia markets should be regularly done. Manufacture and storage had little effect on AFM1 content in milk and dairy products, therefore, new or modern technologies for detoxification of milk should be further studied.
