PURE Bioscience Provides Update: Expanding Use of PURE Control® Antimicrobial in Produce Processing; Expanding Use of PURE® Hard Surface Disinfectant

February 28, 2018

SAN DIEGO (Feb. 28 - 2018) – PURE Bioscience, Inc. (OTCQB: PURE), creator of the patented non-toxic silver dihydrogen citrate (SDC) antimicrobial, provided an update on the expanded use of FDA approved PURE Control® antimicrobial for application directly onto produce during processing and the expanded use of PURE Hard Surface disinfectant.


PURE Control - Produce Update

The first customer for PURE Control, Taylor Farms, is North America’s largest supplier of salads, fresh-cut vegetables and healthy fresh foods. It serves leading customers in the foodservice, retail produce, and retail deli segments of the fresh business.

  • In the fall of 2017, Taylor Farms began a pilot test applying PURE Control as an added intervention step on one processing line in its Salinas, CA, plant to eliminate pathogens causing foodborne illness, including E. coli, Listeria, and Salmonella.
  • The processor conducted extensive use validation studies (including efficacy and organoleptic), on the way to evaluating the use of PURE Control in its US processing plant network. 
  • Processors typically seek a 1 log reduction* in pathogens from an intervention or processing aid. Testing at produce processors, including Taylor Farms, consistently exceeded expectations, indicating pathogen reductions averaging 3 logs – or 99.9%.
  • Earlier this month, Taylor Farms expanded its use of PURE Control to a second line in the first plant, initiated installation on multiple lines in a second plant in Salinas, CA, and developed plans to expand to a third plant in calendar Q2. These plants supply produce to leading foodservice chains as well as to retailers.

A growing number of produce processors continue to be in various stages of testing PURE Control, and testing results to date have been positive. These processors supply fresh and/or frozen produce. The sales cycle for PURE Control for each customer will continue to involve varying amounts of validation and optimization testing by those customers.

The Company estimates that sales of PURE Control to the average produce processing plant can generate approximately $1 million in annual sales per plant/year.

Expanding Use - PURE Hard Surface

Food Transport

  • As previously announced, PURE’s new truck sanitization solution (using PURE® Hard Surface disinfectant) is being rolled out by one of the largest foodservice distribution companies.
  • Several other large food transport companies are in various stages of testing.


  • Beginning early in calendar Q2, use of PURE Hard Surface will be rolled out by a blue chip national casual dining chain.


  • In addition to PURE Control, Taylor Farms has been PURE’s leading adopter of PURE Hard Surface for environmental and surface disinfection in its processing plants, and is currently using it in a growing majority of its 14 plant network. Within each plant, additional applications are being added regularly (including the Company’s food transport sanitization solution).
  • The Company continues to on board additional food processing/manufacturing plants (most recently two household name national brands) while expanding applications within its customer portfolio of 70+ food processors.

Hank R. Lambert, CEO of PURE said, “While slower than first anticipated, the validation that comes from industry leading Taylor Farms expanding the use of PURE Control gives us confidence that our revenue growth will accelerate. We believe this is the start of our meaningful penetration into the $300+ million US produce processing aids market.

“In addition, because of Taylor Farms preeminence, we believe its validation of PURE Control will encourage others in the produce processing industry to move more quickly.

“We are also encouraged by the growing momentum for PURE Hard Surface among food transport companies, food processors and restaurant chains,” concluded Lambert.
