“We would bring it in and let them implement it as throughput,” Spinazzola said. “It’s very important for us to reduce our risk and to protect our whole supply chain. We’re trying to drive this throughout our system, not just in our lettuces and wash waters but through our tomatoes and other commodities. We applaud this continuous improvement.”

The USDA researchers wrote about SmartWash in a 2011 Journal of Food Science article.

(Correction: Because of a source’s error, this article originally incorrectly characterized U.S. Department of Agriculture researcher Yaguang Luo’s comments that the T128 SmartWash system improved the chlorine’s efficacy in preventing pathogen cross contamination.)

Just to understand, this is simly a system to prolong chlorine? Should we not be looking intio systems which are chlorine free for obvious reasons?

Chlorine Dioxide is the answer and is better and easier safer and will do more for safe food production in 20 yrs than chlorine has done in the last 100 yrs.

I agree with your comment Devlin, the SmartWash manufactures have simply taken an age old treatment method and made it marginally more effective. The recent Taylor Farms recall, which I'm assuming was treated with SmartWash, shows that chlorine, no matter how stable it is, is still highly susceptible to organic loading and pH fluctuations. Chemistries like Peracetic Acid, which is the most effective alternative to chlorine, are not affected by pH fluctuations and are immensely more stable in high organic loading. With any type of Chlorine being a known carcinogen, I applaud the companies out there who are promoting effective alternatives to chlorine, rather than trying to make old technology more effective. You hit the nail on the head with your comments Devlin, the industry should be embracing alternatives to chlorine like APC Technology (Activated Peroxygen Chemistry), which provides high efficacy against general coliforms as well as fungal and molds without the headaches and risk factors that are inherent in chlorine.nologies.
