Facing South Florida: The Business Of Lobster
MIAMI (CBSMiami) — In an upscale portion of Hong Kong, the Boat Dweller Restaurant is renowned for its live seafood. Tanks showcase the freshest offerings from around the world – but few items on the menu are likely to capture a diner’s attention or have the appeal of the Florida Spiny Lobster.
With one of the fastest growing economies, and an exploding middle class that extends onto the mainland, the Chinese have developed a taste for the better things in life ‘ and Florida lobster is surely one of them.
For the lobster, this was the culmination of a 9,000 mile journey ‘ a journey that in recent years has transformed the commercial fishing industry in Florida. Before the Chinese started buying their lobsters, the fishermen of the Florida Keys were getting just $3 a pound for their catch with almost all of it being sold in local restaurants.
Boat captains from Key West to Miami were struggling to survive. At $3 a pound commercial fishermen were losing money ‘ they claimed to need $4 just to break even.
But by 2010 and 2011, the Chinese had planted their flag in the Keys, driving up the price to as high as $24 a pound.

Deposition of Bacteria and Bacterial Spores by Bathroom Hot Air Hand Dryers – Applied and Environmental Microbiology
Hot air hand dryers in multiple men’s and women’s bathrooms in 3 basic science research areas in an academic health center were screened for their deposition on plates of: i) total bacteria, some of which were identified; and ii) a kanamycin resistant Bacillus subtilis strain, PS533, spores of which are produced in large amounts in one basic science research laboratory. Plates exposed to hand dryer air for 30 seconds averaged 18-60 colonies/plate but interior hand dryer nozzle surfaces had minimal bacterial levels, plates exposed to bathroom air for 2 minutes with hand dryers off averaged ‘1 colony, and plates exposed to bathroom air moved by a small fan for 20 minutes had averages of 15 and 12 colonies/plate in two buildings tested. Retrofitting hand dryers with HEPA filters reduced bacterial deposition by hand dryers ‘4-fold, and potential human pathogens were recovered from plates exposed to hand dryer air whether or not a HEPA filter was present, and from bathroom air moved by a small fan. Spore-forming colonies, identified as B. subtilis PS533 averaged ‘2.5-5% of bacteria deposited by hand dryers throughout basic research areas examined regardless of distance from the spore forming laboratory, and these were almost certainly deposited as spores. Comparable results were obtained when bathroom air was sampled for spores. These results indicate that many kinds of bacteria, including potential pathogens and spores, can be deposited on hands exposed to bathroom hand dryers, and that spores could be dispersed throughout buildings and deposited on hands by hand dryers.
Importance While there is evidence that bathroom hand dryers can disperse bacteria from hands or deposit bacteria on surfaces, including recently washed hands, there is less information on: i) the organisms dispersed by hand dryers; ii) if hand dryers provide a reservoir of bacteria or simply blow large amounts of bacterially contaminated air; and iii) if bacterial spores are deposited on surfaces by hand dryers. Consequently, this study has implications for the control of opportunistic bacterial pathogens and spores in public environments including healthcare settings. Within a large building, potentially pathogenic bacteria including bacterial spores may travel between rooms, and subsequent bacterial/spore deposition by hand dryers is a possible mechanism for spread of infectious bacteria including spores of potential pathogens if present.

Restroom Hand Dryers Suck Up Feces Particles and Spray Them All Over Your Hands
Washing your hands is one of the easiest ways to stop the spread of germs, right? Well, your office hand dryer might actually be spreading fecal bacteria’onto your hands and throughout your building.
Scientists comparing normal bathroom air to that blasted from hand dryer nozzles have found far more bacterial colonies develop in samples exposed to the’latter. The results were published this month in the journal Applied and Environmental Microbiology.
‘Bacteria in bathrooms will come from feces, which can be aerosolized a bit when toilets, especially lidless toilets, are flushed,’ study author Peter Setlow told Newsweek. The simple movement of lots of people in and out of the bathroom, shedding microbes from their skin, he said, adds to the messy picture.
Hand dryers suck up bathroom air and spew it out at speed. So, in the brief moments your hands rest below the nozzle, they’ll be exposed to far more air than usual’and far’more bacteria.
In the study, researchers searched 36 bathrooms at the University of Connecticut School of Medicine for a harmless, lab-engineered strain of bacteria Bacillus subtilis called PS533. Unlike other types of B. subtilis often’found in soil, this strain is only’found in laboratory environments.
