Dairy animals have always been one of the most studied
animal species in terms of animal welfare [1], Nonetheless,
there are important welfare issues that have yet to be re-
solved.,e purpose of this research was to determine the ex-
istence of infecting microorganisms and their antibiotic
resistance patterns in the dairy farm environment, which
could pose veterinary and public health risks by infecting
animals and contaminating milk, water, and feces with
antimicrobial-resistant avian strains as a result of poor
milking hygiene.,e most common disease-causing bacteria in the milk
are Mycobacterium bovis, Salmonella spp., Corynebac-
terium spp., Coxiella burnetii, Clostridium perfringens,
Brucella, Staphylococcus spp., Yersinia enterocolitica,
Campylobacter jejuni, Mycobacterium avium, Escher-
ichia coli, Listeria spp., and coliforms [4, 5], as Gram-
negative opportunistic environmental bacteria, have
been classified.During the
twentieth century, antibiotics significantly reduced
mortality associated with infectious diseases; however,
their widespread and repeated use in animal farming has
resulted in the emergence of bacterial multidrug resis-
tance (MDR); as a result, the presence of antibiotic-re-
sistant populations transforms infections that were once
treatable into potentially life-threatening events.Mastitis caused by E. coli is typically
sporadic, with symptoms ranging from mild to severe
and even fatal [6].Meal-borne infection, on the other hand, is caused by
ingesting viable pathogenic bacteria along with the food
[3].
