Readers ask: How Does The Use Of Antibiotics In Livestock Contaminate The Water?

How do antibiotics affect livestock?

The benefits of antibiotics in animal feed include increasing efficiency and growth rate, treating clinically sick animals and preventing or reducing the incidence of infectious disease.

What is a consequence of the use of antibiotics in agriculture?

Antibiotic resistance that arises in animal husbandry affects such zoonotic pathogens as Salmonellaserovars and Campylobacterspp., both of which are associated with diarrheal diseases, and human and animal commensals such as Escherichia coli and enterococci.

Why is it a bad idea to use antibiotics in the food of farm animals?

Using antibiotics to promote animal growth or reduce feed requirements is a bad idea. Widespread use of these drugs induces microbial resistance, making the antibiotics ineffective against human disease.

What are the disadvantages of feeding livestock antibiotics?

Widespread antibiotic use has led to multidrug-resistant pathogens. A joint National Research Council/Institute of Medicine panel has concluded that antibiotic-resistant human diseases have “clearly occurred” due to bacteria from antibiotic-treated livestock.

Do antibiotics in animals affect humans?

Using antibiotics in animals may raise the risk of transmitting drug-resistant bacteria to humans either by direct infection or by transferring “resistance genes from agriculture into human pathogens,” researchers caution.

What are the side effects of antibiotics?

Is chicken with antibiotics bad?

A. It’s not the antibiotics that are harmful; it’s the resistant bacteria created by their use in poultry. People who ingest these bacteria can develop infections that are resistant — that is, they won’t respond — to the antibiotics doctors commonly use to treat them.

Does eating animals treated with antibiotics affect human resistance?

Bottom Line: There is no clear-cut link between antibiotic use in animals and resistant bacteria infections in humans. The risk to human health is likely to be small, since adequate cooking destroys bacteria in food.

What antibiotics are used on farm animals?

Approximately 70 percent of the volume of antibiotics used in animals are ionophores and tetracyclines. Ionophores aren’t used in human medicine, and tetracyclines, although listed as an antibiotic important to human medicine, only have a 4 percent human usage rate.

How do antibiotics promote growth in animals?

Antibiotics increase the efficiency of animal growth by inhibiting the growth of microbes in the gastrointestinal tract which triggers immune responses in the host (Gaskins et al., 2002).

What are some alternatives to treating livestock with antibiotics?

The classes of antibiotic alternatives that are available to increase animal productivity and help poultry and pigs perform to their genetic potential under existing commercial conditions include probiotics, organic acids, phytogenics, prebiotics, synbiotics, enzymes, antimicrobial peptides, hyperimmune egg antibodies,
