Some manufacturers of commercial equipment for sanitizing produce have developed small-scale units suitable for consumer and foodservice use. Systems based on use of electrolyzed water are being marketed by Sterilox Technologies, Inc. (www.steriloxtechnologies.com) and Hoshizaki America, Inc. (www.hoshizakiamerica.com). Small-scale systems based on ozone are being marketed by Sterilion Ltd (www.performancesystems.com/medical.htm) and UltrOzone (UC Davis Postharvest Technology Center; 1-866-21-OZONE).
A number of commercial fruit and vegetable wash formulations intended for consumer use are being marketed, but little information is available about their performance in reducing microbial populations. Fit®, a produce wash produced by Procter & Gamble Co. and marketed for a number of years, did show some antimicrobial activity in addition to removing dirt, wax, and other residues [117,118], although no claims were made by the company that the consumer product had antimicrobial activity. They did make such a claim for a "Pro Line Fit'' intended for commercial rather than consumer use. Fit is now marketed by HealthPro Brands, Inc. (www.healthprobrands.com). JohnsonDi-versey markets a Hard Surface Sanitizer/Fruit & Vegetable Wash (Product 4444) claimed to have antimicrobial activity (www.jwp.com/jwp/ProdInfo.nsf/; click on foodservice, then sanitizers). Another product with documented antimicrobial activity is Pro-San®, previously marketed as Vegi-Clean® (www.microcideinc.com/prosan.htm). A product derived from oranges and other GRAS ingredients and claimed to have antibacterial properties is marketed under the name CitroBio for postharvest processing, use in retail misting systems, or as a produce wash for consumers (www.citrobio.com). Grapefruit seed extract (Citricidal®) is reputed to have antimicrobial properties (www.biochemresearch.com) and is being marketed as a consumer-use cleaner and disinfectant for fruits and vegetables (www.pureliquidgold.com). Other produce washes include: Veggie Wash® marketed by Beaumont Products (www.citrusmagic.com), Nature Clean Fruit & Veggie Wash (claimed to remove bacteria) (www.smallplanetinc.com, www.healthyhomeservices.ca, www.frankross.com), CleanGreens! (www.cleangreensinc.com), and Organi-clean (www.organiclean.com).
In addition to these commercial products, recipes for fruit and vegetable washes can be found on the internet. Typical examples include diluted 3% hydrogen peroxide (www.wellnesstoday.com), and vinegar and 3% hydrogen peroxide sprays applied individually to produce (http://myexecpc.com/ ^mjstouff/articles/vinegar.html). One source suggests use of 35% hydrogen peroxide around the house, a potentially dangerous recommendation; specific uses for produce treatment call for use of 3 or 5% solutions (http:// h2o2hydrogenperoxide.com/additrion.html).
