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.
Although originally thought to kill bacteria by attacking multiple cellular targets, triclosan was recently shown to target a specific bacterial fatty acid biosynthetic enzyme, enoyl-[acyl-carrier protein] reductase, in Gram-negative and Gram-positive bacteria, as well as in the Mycobacteria.riclosan is the active ingredient in a multitude of health care and consumer products with germicidal properties, which have flooded the market in recent years in response to the public's fear of communicable bacteria.
