Crew trainers are  responsible for training all new cre â¦ w members.hey work in drive thru presenting food, or they cook in grill. Some crew members also are cashiers on front counter or in the drive thru. Some crew members have a job cleanin â¦ g the front lobby as they call it. I know this because I work at a McDonalds.
Triclosan is toxic to aquatic bacteria at levels found in the environment. It is highly toxic to various types of algae and has the potential to affect the structure of algal communities, particularly immediately downstream of effluents from wastewater treatment facilities that treat household wastewaters.
Currently the only use for which triclosan has been shown to be effective is as an anti-gingivitis ingredient in toothpaste, said Kweder. These products often sell for slightly more than regular soaps, so consumers are paying a premium for something which may be no better, or even worse, than plain soap and water.
