Pesticides in Fruit

​​​​The current study protocol has been designed to support routine analytical laboratories testing pesticide residues in agricultural commodities. The PT will be used to assess the various matrices represented in the AOAC food composition triangle (Figure 1) over the course of five years. For the 2017/2018 financial year PTs will focus on pesticides in fruit, a high carbohydrate, low protein and fat matrix. These are Class A commodities, primarily of plant origin. The matrices selected each represent one of the major subsections in this class: orange, a citrus; apple, a pome fruit; peaches a stone fruit and table grapes a representative of berries and other small fruit.

Specific attention has been paid to tailoring the scheme to current export limits as well as maximum residue levels for the South African market. The target pesticide and commodities were selected to match the growth season within South Africa. Pesticides selected for analysis in this PT represents various chemical classes associated with the specific commodity selected. Thereby accommodating the routine analysis performed by the majority of laboratories at the time the proficiency test material is circulated.
