World Antibiotic Awareness Week (WAAW) is an annual World Health Organization campaign held in November which aims to increase awareness of global antibiotic resistance and to encourage best practices among the general public, health workers and policy makers to avoid the further emergence and spread of antibiotic resistance. In chicken farms and during antibiotic-free poultry breeding, chickens are used without antibiotics; and all stages of chicken rearing -from hatchery to the end of the production period- are under supervision of nutrition specialists and veterinarians. Eggs produced by such chickens are called antibiotic-free eggs. In order to achieve sustainable public health and put emphasis on using healthy and antibiotic-free foods, Saleh Kashmar’s Zarrin Tokhm farm uses processed, healthy, and non-antibiotic feed for its laying chickens. Currently Zarrin Tokhm farm is one of the most advanced and modern egg production units in Iran, packing and providing eggs produced in its laying hens, each with a capacity of 80,000 pieces per period.
