Antibiotic usage for disease prevention is permitted in all large poultry-producing countries. Antibiotics are applied for the treatment of intestinal infections such as colibacillosis, necrotic enteritis, and other diseases generally caused by Salmonella, E. coli, or Clostridium spp

Negative Effects

11.  Effects of drug residues in meat
 Drug hypersensitivity reaction
 Carcinogenic effect
 Mutagenic effect
 Teratogenic effect
 Disruption of Normal Intestinal Flora

12.  Reduce normal microbiota making the bird more
susceptible to pathogens
 Weaken the immune system, compromise liver function
and impair performance.
 Aminoglycosides and sulpphonamides can compromise
kidney function and impair mineral absorption
Negative effects contd.

13.  Only give antibiotics to animals under veterinary supervision.
 Not use antibiotics for growth promotion or to prevent
diseases in healthy animals.
 Vaccinate animals to reduce the need for antibiotics and use
alternatives to antibiotics when available.
 Promote and apply good practices at all steps of production
and processing of foods from animal and plant sources.
 Improve biosecurity on farms and prevent infections through
improved hygiene and animal welfare.
