Sampling of imported product is randomly assigned by an automated import information system after the shipment has arrived in the United States and has been presented for import re-inspection. A sample is collected from a shipment and sent to FSIS labs for testing. Under routine verification sampling, the importer can voluntarily hold the product at the official import establishment pending Agency testing results.
Positive samples from imported products result in an intensified level of subsequent shipments from the foreign establishment. Under this intensified sampling, the next 15 shipments are tested and FSIS requires that the product be held during this period.See the updated reports at USDA FSIS Constituent Update News and Events.
