The September issue “Editor's Roundup” (“Hormone ban marks 20 years,” page 4) reported that USDA's Food and Drug Administration pulled its approval for the use of enrofloxacin (Baytril) for treatment of bacterial infections in poultry. The article incorrectly stated the action was taken due to concerns about the development of antibiotic-resistant Salmonella being passed to humans through poultry products.

In actuality, the resistance concern is Campylobacter, not Salmonella. The story was correctly reported in a page-6 piece in the same issue, “Baytril use in poultry banned.”

The ruling, effective Sept. 12, was specific to poultry production and does not apply to other approved uses of enrofloxacin, a member of the fluoroquinolone class.

We apologize for the error and any confusion it may have caused.
