The Public Health Agency of Canada estimates that roughly one in eight Canadians (or four million people) get sick each year due to domestically acquired foodborne diseases. This is estimated to cost the Canadian economy more than $2 billion per year. A common source of domestic infections is poorly handled and contaminated foods materials, and bacterial pathogens such as Salmonella enterica, Clostridium perfringens, Escherichia coli and Listeria monocytogenes account for approximately 90% of these illnesses. Therefore, there is a pressing need to develop nontoxic and effective disinfectant agents that can be safely used in kitchens across Canada. EastGate Pharmaceuticals recognizes the importance of reducing the exposure of these pathogens and aims to design natural consumer products that will limit their spread. Recently, they have developed a nano-delivery-based line of antimicrobial hand sanitizers and fruit and vegetable washing solutions derived from natural, non-toxic ingredients. The initial formulations of these antimicrobials have demonstrated limited activities against common foodborne bacterial pathogens. By collaborating with Dr. Khursigara at the University of Guelph, EastGate aims to improve the nano-delivery mechanism of their natural antimicrobials to enhance their antibacterial activities. Dr. Khursigara's team will use existing antimicrobial testing guidelines that have been established by Health Canada and Public Health Ontario to assess the efficacy of the novel antimicrobial formulations against these bacterial pathogens. EastGate Pharmaceuticals will use this information to develop better antimicrobial formulations and nano-delivery mechanisms that could potentially be adapted to safely deliver other types of drugs in the human body.

加拿大公共卫生局估计，由于国内获得的食源性疾病，每年大约有八分之一的加拿大人（或四百万）生病。据估计，这将使加拿大经济损失超过20亿加元。家庭感染的一种常见来源是处理较差和受污染的食物材料，细菌病原体，例如沙门氏菌肠，灌注梭状芽胞杆菌，大肠杆菌和单核细胞增生李斯特氏菌，约占这些疾病的90％。因此，迫切需要开发无毒和有效的消毒剂，这些消毒剂可以安全地用于加拿大的厨房。 Eastgate Pharmaceuticals认识到减少这些病原体暴露的重要性，并旨在设计自然消费产品，以限制其蔓延。最近，他们开发了一种基于纳米递送的抗菌洗手液和水果和蔬菜洗涤液，这些系列源自天然，无毒成分。这些抗菌剂的初始配方表明，针对普通食源性细菌病原体的活性有限。 Eastgate与圭尔夫大学的Khursigara博士合作，旨在改善其天然抗菌药物的纳米分娩机制，以增强其抗菌活动。 Khursigara博士的团队将使用加拿大卫生部和安大略省公共卫生制定的现有抗菌测试指南来评估新型抗菌剂配方对这些细菌病原体的功效。 Eastgate Pharmaceuticals将使用此信息来开发更好的抗菌剂配方和纳米递送机制，这些机制有可能适应人体中的其他类型的药物。
