Unfortunately even fruit and vegetables aren't safe.
Syphilis and TB antibiotics are being used to combat disease on orange trees in Florida:
The E.P.A. has proposed allowing as much as 650,000 pounds of streptomycin to be sprayed on citrus crops each year. By comparison, Americans annually use 14,000 pounds of aminoglycosides, the class of antibiotics that includes streptomycin
In its decision to approve two drugs for orange and grapefruit trees, the E.P.A. largely ignored objections from the C.D.C. and the F.D.A., which fear that expanding their use in cash crops could fuel antibiotic resistance in humans.
scientists are especially worried that the drugs will cause pathogenic bacteria in the soil to become resistant to the compounds and then find their way to people through groundwater or contaminated food.[1]
Several lawmakers wrote to the EPA last month to urge a rethink of the policy given legitimate scientific concerns around the issue of antimicrobial resistance. To quote the letter:
Antibiotics are life-saving medicines and, except in extraordinary circumstances, should only be used to treat specific illnesses in people and animals," the lawmakers wrote. "EPA's assessments appear to ignore scientific evidence, violate the principle of judicious antibiotic use, and could create unnecessary harm to human health by authorizing an unprecedented amount of medically important antibiotics to be used for plant agriculture.[2]
