The Georgia Department of Agriculture (GDA) Laboratories protect consumers by ensuring their food, fuel, seed, and feed meet the highest quality standards.


  • Laboratory Program

    Together with GDA's licensing and inspection programs, the GDA Labs protect consumers by ensuring their food, fuel, seed, and feed meet the highest quality standards.

    We support regulatory actions by testing seed, feed, fuel, fertilizer, food, dairy products and pesticides, and calibrating devices that measure weight and volume.

  • Our Labs

    Microbiology Lab

    The Microbiology Lab helps ensure the safety of Georgia’s food supply. The lab tests for foodborne pathogens such as Salmonella spp., Listeria monocytogenes, and E. coli, and reviews for other contaminants from insects and rodents, aflatoxin, and staph enterotoxin. The lab also tests pet foods for contaminants.

    All these tests are part of a food surveillance program that ensures the safety of Georgia’s food supply, from retail ready-to-eat foods to food manufacturing facilities.

    The lab also aids federal Food Safety initiatives with USDA and FDA involving tests for food, feed, milk, and meat products.

    State Seed Lab

    The State Seed Laboratory tests seed for Georgia and surrounding states to ensure quality and consistency. If you want seed samples tested.  See details on the next tab.

    We’re a regulatory agency but we also test certified seed and farmer’s seed. All major agricultural crops, vegetable seeds, and grass seeds can be tested at our lab. We conduct purity testing, germination testing, vigor testing, noxious weed exams. Special testing is offered upon request.

    Feed Lab

    The Feed lab tests pet foods and livestock feeds to verify the guaranteed analysis on the label, ensuring that the nutritional needs of animals are met and their diets are safe and balanced.

    Fertilizer Lab

    The Fertilizer lab tests commercial and consumer fertilizers to verify the nutrient content meets the products’ stated guarantees. Ingredients need to be reported accurately to ensure crop health and productivity.

    State Fuel Oil Lab

    The State Fuel Oil lab helps keep Georgia moving. Fuel impacts all aspects of life – agriculture, transportation, and other vital activities would suffer if its quality isn’t safeguarded. The Lab protects fuel and other petroleum products for purity, performance, octane rating and other quality standards. The Lab also tests kerosene and antifreeze as they’re vital to life in the winter.

    State Weights & Measures Lab

    The State Weights & Measures lab makes sure that all food scales, transportation scales, weights used for commerce, and volume provers are properly calibrated. Georgians deserve to get the full measure of every pound and gallon they pay for.

    For weight measurements, the lab conducts precision and tolerance calibration testing. Its other duties include volumetric testing of metal provers, length testing for steel tapes and rigid rulers, strength testing for weight carts, overseeing Georgia’s grain moisture testing program, and inspecting the lottery balls once each month for the Georgia Lottery Commission.

    Pesticide Lab

    The Pesticide laboratory ensures that the food produced and consumed in Georgia is safe to eat. The lab tests food, complaint samples, and pesticide products, and it polices state pesticide laws. The lab plays an integral role in the Food Safety Division’s food surveillance program.
