The sample should be collected in such a manner that air bubbles are not entrapped. Semisolid s ples should be collected the same way. The collected samples should be refrigerated (blue ice, 4 C) for transport and analyzed within seven (7) days of collection (14 days with presery 6.5 Pesticide Residue Sampling 6.5.1 Concerning Re-entry and Worker Safety All samples should be from the plant foliage (leaf tissue) when pesticides are applied to the foliage. Sometimes areas other than the plant foliage may be in question, such as the dripline area surface soil and/or the 1 (leaf litter) under the trees. The sample should be large enough to fill a no "lunch bag" and be taken from several plantings. 6.5.2 Conerning Consumer Safety The edible portion of the plant or fruit should be collected. The sample should contain approximately one (1) pound of material taken from several plants. Usually six to eight whole plants or fruit pieces will make up a good sample. 6.6 Sample Handling Policy Proper sample containers, ple volumes, p eryatives, and holding times are essential to providing reliable data.
