Highlights
- The highest Aflatoxin M1 (AFM1) incidence was detected for yogurt samples (93.8%) with an average of 35.1±40.4 ng/kg.
- Upper bound estimated daily intake of AFM1 for high consumption population was 0.456 ng/kg body weight (bw)/day.
- This study revealed a potential risk for the population of North Macedonia exposed to AFM1.

Highlights
- Mycotoxins levels in 5 out of 55 samples were above the European Union (EU) limit.
- The highest co-occurrence of mycotoxins was found between aflatoxin B1 and ochratoxin A.
- Aspergillus flavus and A. niger were the most toxigenic species identified.
- This study alarms us about the hygienic risk raised by Tunisian consumers.

Highlights
- Aflatoxin M1 (AFM1) was detected in 4 (9.5%) of Ultra High Temperature (UHT) milk samples.
- The concentration range of AFM1 was 2.8-7.4 ng/L in the UHT milk samples.
- None of the positive samples had AFM1 levels exceeding the maximum permissible limit (50 ng/L).
- AFM1 seems to be no serious public health problem in Sharjah, United Arab Emirates.

Highlights
- Artemisia dracunculus (tarragon) Essential Oil (EO) showed significant antifungal potential.
- Main fragments of tarragon EO were beta-cis-ocimene, estragole, and beta-trans-ocimene.
- Growth inhibitory activity of tarragon EO enhanced when was encapsulated as nanoemulsion.
