erving counter in three dining facilities at Ft. Bragg, NC during Sept to Dec 1989 following application of the 0.05% dust formulation to cracks and crevices at 32-45 mg total application(1). Abamectin was initially detected in the bread at 8.4 ppb, and was 3.6 and 3.3 ppb at 1 and 3 days posttreatment, respectively; abamectin was initially detected in the lettuce at 6.9 ppb and was 2.6 ppb at day 1(1). It is noted that no heating or air conditioning was used in the dining facilities during the study.
