POSTHARVESTHANDLINGPostharvest Handling and Packing FacilitiesOnce produce has been harvested, care must be takento prevent either direct orcross contamination of the cropduring grading, washing,packing and shipping. Severalfoodborne illness outbreaks infruits and vegetables havebeen traced back to packingoperations. ImplementingGAPs and Good Manufacturing Practices (GMPs) duringpost harvest handling and packing can reduce microbial risks tofruits and vegetables. Adopting post harvest GAPs and GMPs arealso good for produce quality since most practices that reducegrowth of human microbial pathogens will also reduce post harvestdecay.Cool produce quickly after it has been harvested. Target pulptemperatures should optimize produce quality and ideally willminimize microbial growth. Maintaining this “cold chain” fromharvest to storage to shipping to retail display is essential to reducemicrobial (and plant) pathogen growth.Water used for washing, cooling, or icing produce must bepotable. Wash water and dump tanks can spread pathogens throughcross contamination. Disinfection of this water can reduce theserisks. Avoid cooling water bath temperatures that are more than10 F cooler than the produce pulp temperature, so that water is notdrawn into produce. This concern is highest for tomatoes, peppers,apples, potatoes, mangoes and cantaloupes.The produce handling facilities, packing areas and trucks usedfor shipping must be kept clean through scheduled washing andsanitizing programs. Produce waste should be properly disposed ofand runoff from produce fields should be prevented from enteringpacking areas. Birds, rodents, insects, and other pests should beexcluded from the packing areas.One of the most important practices to reduce post harvestmicrobial contamination of produce is worker education and training. Trained workers are important and valuable because they canidentify factors that increase fruit damage during packing such asrough handling and sharp edges on packing lines. Damaged or cutfruit can harbor pathogens and decay organisms. Effective trainingthat encourages good communication and worker participation is avaluable postharvest tool.Finally, keep records so that each package leaving the farm canbe traced to the field of origin and the date on which it was packed.Traceback information is essential for both third party auditing forfood safety as well as for inspectors in the event of a foodborneillness outbreak.Trained workers are important and valuable becausethey can identify factors that increase fruit damageduring packing such as sharp edges on packing lines.
