Firefighters' dirty drinking water, and "shift food"

The Missoula Technology and Development Center (MTDC) just published the 12th edition of the "Wildland Firefighter Health and Safety Report" written by Brian Sharkey (if you don't have the user name and password, go HERE):

Shift food...better than...?
Their research shows that when firefighters eat "small items" during the shift, every 1-2 hours, their total work output increased by 15-20%. Most of the firefighters preferred the shift food to the standard sack lunch. But, almost any food is better than the standard sack lunch, especially after eating the damn ham on Wonder Bread sandwiches for 2 weeks. How does the saying go? When trees burn pigs die?

Water bottles are filthy
Researchers found loads of nasty stuff in the water bottles and drinking systems of firefighters. They tested the bottles or systems of 15 firefighters and found that several of them had high concentrations of molds and yeasts. Legionella-like bacteria, which causes Legionnaires' disease, were detected in one water bottle and in one drinking tube.

The fatality rate from Legionnaires' disease has ranged from 5-30% according to Wikipedia. Legionellosis infection occurs after inhaling water droplets containing the bacteria. Pontiac fever is caused by the same bacterium, but produces a milder respiratory illness without pneumonia which resembles acute influenza.

The molds growing in the water systems could be causing allergic responses in some firefighters. But water purifier technology, chlorine dioxide tablets, was found to clean the systems very well. Aquamira and Camelbak sell these tablets. The Camelbak site has instructions about how to clean their products.

In 2005 there was an outbreak of Legionnaires' disease in Rapid City, South Dakota that resulted in one death and 19 hospitalized and was sourced to a small ornamental fountain in a popular Mexican restaurant. The mayor of the city was one of those hospitalized. The restaurant went out of business and was torn down.

OK, quit reading this blog....get off your butt and go clean your water bottles and Camelbak!
