Getting product reject is one of the worse case that might happen. Well, it cannot be helped. Even after all the careful and strict practices, substandard products can only be minimized but not avoided.
If the product under reject status simply does not comform to specifications and no threat to human health. Then, it can be brought back to plant for reprocessing. It is the routine. There is additional processing and transportation cost, but at least, the product is recovered.
It is the case when produce is still in facility or distributed in local. However, it is a completely different story when it is exported abroad. Seminar resource persons often told, when Japan found the imported product is substandard, the whole shipment will be immediately dump to sea. No negotiation and without prior notice. You have just lost a hefty amount of cash. Need to work extra hard to recover.
New.abs-cbn.com posted on March 26, 2016. About 34.78 tons substandard bananas where destroyed and dumped to landfill in Shenzen City, China. Poor bananas, gone as compost.
Why it was declared as substandard? Test samples was found to have excessive pesticide residue, carbendazim. No exact value was reported. Maybe not all babanas were substandard, but testing batch majority is not industry practice. If one sample is found bad, the whole cargo will be considered bad. It is like a white bond paper with dot on middle. Not every part is dirty but a single dot makes it unclean as a whole.
Carbendazim is a fungicide with many recorded recored health effects. Listing them all here will create a wall of text even I don’t want to read. The maximum pesticide residue limit (MPRL) is 0.1 to 0.7 mg/kg. Use in some countries is unlawful.
The shipment amounted to 33 thoudand USD or a little more than 1.5 million pesos. That was a lot of cost to recover.
