Know How We ALL Knowingly or Unknowingly Consume Antibiotics and How it Effects Our Health
Billions of microbial cells live in the guts of humans and other animals. Research on these vast bacterial populations, called microbiomes, is just getting started, but scientists already know that some microbial boarders play a crucial role in breaking down nutrients in our diet. Some have also suspected that low-dose antibiotics, given to farm animals to make them grow bigger, could work by altering the gut microbiome.
To test this hypothesis, a team led by microbiologist Martin Blaser of the New York University School of Medicine in New York City added antibiotics to the drinking water of mice that had just been weaned. The medicine—either penicillin, vancomycin, a combination of the two, or chlortetracycline—was given at doses comparable to those approved by the U.S. Food and Drug Administration as growth promoters in farm animals. After 7 weeks, the group of mice on antibiotics had significantly more fat than a control group drinking plain water, the team reports online today in Nature. “This confirms what farmers have shown for 60 years, that low-dose antibiotics cause their animals to grow bigger,” Blaser says.

Now, Researchers at the University of Copenhagen, Denmark, and University College Cork, Ireland, found that antibiotic concentrations within limits set by US and European Union (EU) regulators are high enough to slow fermentation, the process that acidifies the sausages and helps destroy foodborne pathogens like Salmonella or E. coli.
“At low concentrations and at regulatory levels set by authorities, they could see that the lactic acid bacteria are more susceptible to the antibiotics than the pathogens are.
“Residual antibiotics in the meat can prevent or reduce fermentation by the lactic acid bacteria, but these concentrations do not effect survival or even multiplication of pathogens.”
Antibiotics used as growth promoters or to treat disease in livestock can eventually end up in meat, and regulators in the US and EU have set limits on the concentrations of antibiotics in meat for consumption by humans.
Researchers say that fermented sausages occasionally cause serious bacterial infections, but it’s never been understood why that might be….

Very important post, Dr. Karra
Here the sun is rising on the Atlantic Ocean a stunning view from my vacation place in Maine, woke up to read new posts and comment.
happy vacation period, Dr. Aviva.
How to inform the lay public of the importance of this issue?
