An alert RFR recently discovered a container of cubed animal shortening in the middle of a pallet of vegetable shortening. Upon investigation it was determined that there was a fault in the electric eye on the packaging line of the manufacturing facility, and the animal shortening was directed to the wrong pallet. While this particular situation was immediately corrected, RFR's should carefully check pallets to the best of their ability. Obviously, it would be unreasonable to expect a company to break down the entire pallet for inspection, and one incident does not establish a Halachic basis to require such manner of inspection. Nonetheless, a good RFR takes pre-emptive action to avoid even unlikely situations. It is therefore recommended that in the course of inspections, RFR's spot check visible containers within each pallet, particularly when the pallet contains products with high levels of kosher sensitivity.
