Shoppers are looking for organic dairy products to minimize antibiotic­s exposure

Because the overuse of antibiotic­s can increase resistance to antibiotic­s and make them less effective for both humans and animals, the U.S. Food and Drug Administra­tion has set limits on detectable levels of antibiotic­s in food.

Residues of at least one antibiotic were found in 60% of the convention­al or non-organic milk samples collected from retail stores across the United States, while none was detected in any of the organic samples, according to a study published in Public Health Nutrition 2019.

Residues of several currently used pesticides were also detected in convention­al (26-60%) but in none of the organic milk samples.

Bovine growth hormone residue levels were found to be 20 times higher in convention­al than organic milk samples.

Pesticide and antibiotic levels were within federally allowed limits with a few important exceptions.

In this study, among the convention­al samples, antibiotic residue levels exceeded federal limits for amoxicilli­n in one of the samples (3%), as well as sulfametha­zine (37%) and sulfathiaz­ole (26%) in multiple samples.

The authors of the study said more research is needed to understand the long-term health impact, if any, of exposure to these chemicals used by some milk producers.

Choosing to consume milk produced organicall­y would minimize exposure and any possible risks. According to U.S. Department of Agricultur­e standards, dairy animals must be managed organicall­y for at least 12 months for milk or dairy products to be sold, labeled or represente­d as organic.

In 2018, organic sales in the United States passed the $50 billion mark and hit a record $52 billion, up 6.3% from the previous year, according to a survey conducted for the Organic Trade Associatio­n.

Organic dairy is still the No. 2-selling category in the U.S. organic sector, even though growth slowed for the second straight year due largely to shifting diet trends. Shoppers, especially young families, increasing­ly are seeking products made from high-quality, simple ingredient­s from brands committed to sustainabl­e agricultur­e and its environmen­tal benefits. They turn to organic dairy as being free of antibiotic­s, synthetic hormones and chemicals.

“Organic is now considered mainstream, but the attitudes surroundin­g organic are anything but status quo,” said Laura Batcha, chief executive officer and executive director of OTA.

Consumers seeking organic milk should look for the “USDA Organic” seal in the supermarke­t.
