McDonald's overseas plan to stop using antibiotic chicken in the US has not been announced yet
in March 4th local time, McDonald's announced that it would stop using antibiotics - containing chicken in 1.4 thousand stores in the United States, and McDonald's will also provide milk from cows not injected with recombinant bovine growth hormone (rbST). At present, this policy is only implemented in the United States, and other regions, including China, have not yet been announced.
, however, McDonald's announced a "global strategy for the management of antibiotics in edible animals" earlier this week, which pointed out that the use of antibiotics in animal breeding will be restricted and used globally (limited to the types of antibiotics that have a major impact on human health and health. " ). In addition, the strategy also includes detailed guidance and specifications for the use of antibiotics by suppliers.
McDonald's said that over the next two years, farms in the upstream of the US chicken supply chain will strictly enforce the policy to limit the use of antibiotics. For individual sick poultry, the provisions of McDonald's do not limit their use of antibiotics, but the individuals after use will be excluded from the scope of McDonald's procurement.
but the above policy also shows that farms will continue to use antibiotics called ionophores for poultry to ensure the healthy growth of poultry. The antibiotic will not be used in humans, so it will not affect human health.

why should we restrict the use of antibiotics in poultry growth?
first, antibiotics are produced by microorganisms (including bacteria, fungi, actinomycetes) or higher animals and plants in the life process, with a class of secondary metabolites with disease resistant or other activity, which can interfere with other living cell developmental functions. In a simple way, it's germicidal.
next, the bacteria that cause your illness are divided into "sensitive strains" and "resistant strains". After the use of the corresponding antibiotics, most of the sensitive strains will be killed, but a few of the resistant strains will survive. Because resistant strains have genes that resist this antibiotic.
the popular explanation, if the process is repeated many times, that is, the antibiotic is used every time, and the resistance to antibiotic genes will be inherited, causing a substantial increase in the proportion of resistant strains. Then, the effect of antibiotics on the disease will be smaller and smaller until there is no effect.
and the use of antibiotics in the growth of poultry, although it will prevent them from being ill, but the antibiotics used are not completely metabolized, and some of the antibiotics will remain in poultry.
when we eat poultry as food, the remaining antibiotics will be deposited in our body and gradually develop resistance. In this case, the next time we really want to use this antibiotic, the effect will be greatly reduced due to the influence of drug resistance.
