PC, Production lot code.
Numbers in the ‘Percent of each PC in overall total’ column represent the PC-specific proportion of the overall total volume (100%) of grower R/ranch R/lot R romaine or romaine-containing lettuce products processed and shipped by producer A from 2 to 6 June 2013.
Numbers in each row represent the proportion of the various product types out of the total volume for each PC (i.e. denominator = volume represented as percent in the corresponding ‘Percent of each PC in overall total’ column).
Texas and Arkansas both received production code T (PC-T) product which contained romaine lettuce not originating from grower R/ranch R/lot R (9% of all PC-T product in approximate equal volume in both states). However, this product did share the same production line and shift and potentially shared pre-processing wash water thus potential for cross-contamination existed.
