Multiply that one small company by however many are out there and the picture becomes somewhat frightening. If the Rashneesh caused food poisoning in the salad bars so many years back in The Dalles, Oregon, wouldn't it stand to reason the opportunity exists? How would anyone know if shipments were contaminated by any method until after people started to get sick, if then? Also consider that shipments may go to various stores in multiple cities. It is truly a vulnerable situation, unless we grow our own, and by previous posts, even that source can be contaminated by low flying aircraft.
Food service companies and food prep industry is a major concern...think of all the schools and corporations that use this.
Distribution centers also are a prime opportunity.
Re- truckers (ME) It sure did seem odd to me that the ME's all gravitated to this ONE company where the drivers are authorized to "certify the seals" after deliveries.
