National Honey Bee Survey Wax Pesticide Sampling Report
Further sampling summary information can be found at the USDA APHIS National Honey Bee Survey Report page. This report lists the level of detection (LOD) and the prevalence (percentage that the pesticide occurred) in all samples taken across the country as part of wax sampling since 2017. For example, if the prevalence value for a pesticide is given as “10”, the pesticide was detected in 10% of all samples received. Finally, this table also provides the average and the range in ppb (parts per billion) of pesticides found in all of the samples.
Pesticide samples were collected from brood comb wax and processed at the USDA Agriculture Marketing Service (USDA-AMS). Sampling from bee bread was done from 2011 to 2017 and 2020 to 2023. Wax sampling occured from 2017 to 2020 and 2023 to present. Access the bee bread sampling report here.
