The control of mastitis is currently reliant on antibiotic utilization. Nevertheless antibiotics overuse and use without
criteria leads to the development of resistant strains with negative consequences both in animal and public health.
Essential oils (EOs) are classified as GRAS (generally recognized as safe), are provided with antimicrobial
properties and no resistance has been reported after use.
The aim of this study was to evaluate the antimicrobial activity of EOs of aromatic herbs, growing wild in Alentejo
region and widely used in Mediterranean food, against microorganisms isolated from ovine mastitic milk
