Ecolab announces its Tsunami 100 product is the only EPA-registered antimicrobial water additive to reduce pathogens in fruit & vegetable process waters

April 24, 2006 — /BUSINESS WIRE/ — ST. PAUL, Minn. — Ecolab Inc. today announced that its Tsunami 100 product was recently registered by the U.S. Environmental Protection Agency to reduce 99.9 percent of pathogens in process waters used to clean fruits and vegetables. It is the only EPA-registered antimicrobial water additive product on the market that can make such a claim.

Tsunami 100 works against the dangerous pathogens Escherichia coli O157:H7, Listeria monocytogenes and Salmonella enterica in fruit and vegetable processing waters. In addition, it provides control of spoilage and decay-causing non-public health organisms present on the surfaces of post-harvest, fresh-cut and processed fruits and vegetables so product spoilage is minimized and shelf life is enhanced.

“Health standards involved in fresh produce processing are becoming more and more stringent as consumption of fresh produce by health-conscious consumers rises to an all time high,” said John Tengwall, vice president of marketing for Ecolab’s Food & Beverage Division. “We’re proud to be leading the way in meeting the challenge these new standards pose to the fruit and vegetable processing industry by providing proven solutions like Tsunami 100 to help ensure that fresh produce is clean, fresh and delicious.”

Tsunami 100 has low reactivity with organics and soils in process wash waters, making it easier to maintain a consistent dosage for microbial control. It is a versatile product that can be successfully applied in all major processing steps, including multi-stage flumes, chill tanks, coolers and washing in fresh cut, post harvest and further processed facilities.

Tsunami 100 can be used on vegetables and fruits, both whole and cut, with no rinse required. Tsunami 100 is not for use as a hard surface food contact sanitizer.

With 2005 sales of $4.5 billion, Ecolab is the leading global developer and marketer of premium cleaning, sanitizing, pest elimination, maintenance and repair products and services for the hospitality, foodservice, healthcare and industrial markets. Ecolab shares are traded on the New York Stock Exchange under the symbol ECL.
