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.
Its efficacy as an antimicrobial agent, the risk of antimicrobial resistance, and its possible role in disrupted hormonal development remain controversial. Additional research seeks to understand its potential effects on organisms and environmental health. Triclosan was developed in the 1960s. In September 2016, the FDA announced that effective September 2017, it would prohibit the sale of consumer antiseptic washes containing triclosan or 18 other ingredients marketed as antimicrobials due to FDA findings of the lack of efficacy in these products.
