Ionophores look different to other scientists, too

Several organizations have drawn the line distinguishing ionophores from  other types of antibiotics.

The Natural Resources Defense Council, a non-profit, environmental advocacy  group, acknowledged the difference in an issue brief, “Pharming Chickens:  It’s time for the poultry industry to demonstrate antibiotic stewardship.”

The article asserted that the widespread use of antibiotics in poultry production  was breeding drug-resistant bacteria that threaten human health, but in an  endnote, added: “There has been little indication to date that the use of  ionophores [to treat coccidiosis in animals] promotes resistance to antibiotics  important to human medicine.”

A section on antimicrobial feed additives in The Merck Veterinary Manual —  the veterinary edition of the prestigious Merck Manual long used as a reference  by medical doctors — states that “ionophores…do not have any link or possible  effect on antimicrobial resistance to therapeutic antibiotics in either people or  food animals; to group all antimicrobials together for debate about the risk to  therapeutic antibiotics is ill advised and overly simplistic.”

Ionophores are not listed by FDA nor WHO as medically important to  human medicine.1,2
