Occurrence of aflatoxin M 1 in yogurt of five countries in west Asia region: A systematic review and meta‐analysis

Abstract

Despite the considerable importance of dairy consumption, aflatoxin‐M1 (AFM1) contamination can pose potential health threats for these products. In the present study, we systematically reviewed and conducted a meta‐analysis on the AFM1 contamination in yogurt samples of West Asia region. In the present study, electronic databases including PubMed, Scopus, and web of Science were comprehensively searched for papers published from April 2006 to February 2020 in English language. Of a total of 356 articles found in the initial search, 25 studies were included in our meta‐analysis. All eligible studies were attributed to five out of the 20 west Asian countries. The mean AFM1 concentration in yogurt samples (in ng/kg) was as following: Turkey 137.76 (95%CI: 61.48, 214.04), Lebanon 86.70 (95%CI: 0.00, 217.72), Pakistan 38.43 (95%CI: 9.05, 67.80), Qatar 31.30 (95%CI: 27.5, 35.14), and Iran 28.24 (95%CI: 23.11, 33.36). According to our results, aflatoxin contamination levels in 32.25% of Lebanese, 31.25% of Turkish, 20.95% of Pakistani, 8.27% of Iranian and 0% of Qatari yogurt samples exceeded the European upper limit (i.e., 50 ng/kg). The hazard index (HI) for AFM1 exposure via yogurt consumption was in acceptable range for included countries except for Turkey and Lebanon.

Maternal pre-pregnancy diet and prenatal depression: the mediating role of pre-pregnancy weight status and prenatal inflammation

“…Regarding the association between DII and inflammation, our findings agreed with recent evidence that DII was associated with elevated CRP levels in non-pregnant populations (90,91) . However, DII scores calculated based on dietary data from both pre-pregnancy and prenatal periods (weighted means), was not associated with early-pregnancy inflammatory biomarkers in an ethnically diverse cohort (92) .…”

Aflatoxin‐M1 contamination in cheese of six countries in the West Asia region: A systematic review and meta‐analysis

“…2019; Mohammadi et al . 2021), most were carried out on milk samples. The results of the present meta‐analysis showed that the total concentration of AFM1 in cheese samples from Qatar (197.74 ng/kg), Turkey (142.02 ng/kg), Iran (124.95 ng/kg), Pakistan (122.56 ng/kg), Kuwait (73.65 ng/kg) and Lebanon (63.98 ng/kg) did not exceed the limit recommended (i.e.…”

The role of slope as an environmental variable in plant biodiversity change in Aegean rangelands by SHE analysis: The case of Çakmar rangeland

“…These rangelands are vital for animal husbandry in the eastern Anatolia region due to the challenging topography and short growing season (Koç et al, 2021). Additionally, the use of commercial feeds for animal farming is common throughout Türkiye, impacting the utilization of rangelands (Mohammadi et al, 2021).Environmental variables are also under the influence of this situation. One of the most important of these environmental variables is slope.…”
