Bioniche Life Sciences Inc. (BNC) Release: Most Effective Strategy for Managing E. coli O157:H7 in Beef is a Combination of a Pre-Harvest Intervention and Several Processing Interventions

In their study, the three researchers developed a stochastic, quantitative risk assessment model to evaluate the public health risks associated with consumption of ground beef and beef cuts contaminated with Escherichia coli (E. coli) O157:H7 in Canada. The researchers evaluated the relative effects of pre-harvest and processing interventions on public health risks, comparing the baseline risks from consumption of beef products.

The research included findings from critical systematic review and meta-analysis of published literature, and 20 different intervention scenarios were assessed. The pre-harvest interventions that were assessed included probiotics, an SRP vaccine, and a Type III protein vaccine. Production/processing interventions that were analyzed included hot water wash, steam pasteurization, acid spray chill, dry-aged chill, and water spray chill. The researchers concluded that the most effective strategy for E. coli O157:H7 management includes a pre-harvest intervention and several processing interventions: "Specifically, application of Type III secreted protein vaccination along with a suite of processing interventions provided the greatest relative reduction in risks." The Company's Econiche^TM vaccine is a Type III protein vaccine.

The findings from this study support the Company's ongoing efforts to gain widespread uptake of cattle vaccination with Econiche^TM.

Econiche^TM Regulatory/Market Update

Since October, 2008, the Company has had a full license for its cattle vaccine against E. coli O157 - Econiche^TM - in Canada. In the intervening period, there has been limited uptake by Canadian cattle producers. Those who have adopted the technology have been small producers who have a branded beef product and are concerned about the negative impact of an E. coli outbreak on their brand, and those producers/farmers whose cattle have infected humans with E. coli O157. Outbreaks and recalls associated with E. coli O157 infection and contamination continue to occur on a regular basis, so this public health threat remains a grave concern.

In February, 2008, the Company was advised by the United States Department of Agriculture (USDA) that Econiche^TM was eligible for a conditional license once certain conditions were met. Since that time, the Company has been in regular dialogue with USDA officials about this license.

Most recently, the USDA's Center for Veterinary Biologics issued updated guidance regarding the licensing of vaccines as pre-harvest food safety interventions. Company representatives look forward to discussing this new guidance with the USDA, to collaboratively reach consensus on the path to vaccine licensing in the U.S.

About E. coli O157

Ruminants, primarily cattle, are considered to be the primary carriers of E. coli O157. This bacterium can cause severe illness and can even be fatal when ingested by humans from contaminated meat, vegetables, other food products, or water. Human exposure and infection with E. coli O157 can result in serious health consequences, including abdominal pain and severe bloody diarrhea. In severe cases, kidney damage can occur and progress to serious complications and even death. Lingering, long-term medical conditions can persist in individuals exposed to the bacterium. These include post-infectious irritable bowel syndrome (PI-IBS), reduced kidney function, diabetes, hypertension and reactive arthritis.

An estimated 100,000 cases of human infection with the E. coli O157 organism are reported each year in North America. Two to seven per cent of those people develop haemolytic uremic syndrome (HUS), a disease characterized by kidney failure. Five percent of HUS patients die, many of them children and senior citizens, whose kidneys are more sensitive to damage. Among the many outbreaks recorded, a 1996 Japanese outbreak made more than 9,000 people sick while the Walkerton, Ontario outbreak in 2000 sickened 2,500. A late April E. coli outbreak in New Brunswick has sickened up to 27 residents, many of whom ate at a Jungle Jim's restaurant.
