raw food poisoning

  • FDA already has approved the use of electron beam technology as a pathogen intervention strategy to control the naturally occurring Vibrio vulnificus bacterial pathogen in shellfish.

      Good that it has already been approved by the FDA... step in the right direction
  • Praveen said she and the other researchers also chose the viral pathogens as opposed to bacterial as they were more difficult to treat and also require a host species.
  • if a serving size of 12 raw oysters were contaminated with approximately 100 hepatitis A and human noroviruses, an e-beam dose of 5 kGy (kilograys) would achieve a 91 percent reduction of hepatitis A infection risks and a 26 percent reduction of norovirus infection risks.

      Pretty significant except it still doesn't make me want to eat raw shellfish
  • how electron-beam pasteurization of raw oysters may reduce the possibility of food poisoning through virus.
  • results of this study will be published in the June
  • using a human norovirus surrogate called murine norovirus
  • uses commercial electricity
  • green technology because no chemicals are involved."

16,000 Dead Pigs In The Huangpu: Can You Still Drink Shanghai's Water? | Popular Science - 1 views

    The dead pigs are being thrown into the water, not dying from the water. After being dumped in, they are becoming toxic in the river and emitting poison into the water.  The city of Shanghai relies on the river for the all the drinkable water in the city.  City officials have no idea how toxic the river has become, since no studies were done prior to the findings.  More research showed that the pigs are being dumped into the river because of costs of discarding the dead animal. It is cheaper to dump it, even though it could be toxic to the whole city.  Makes you wonder - we eat dead animals. But, when dumped in drinking water, they become toxic.... Hmmm.....

  • "We've been baking this bread for 60 years, and we're pretty good at it, buddy," said Kenneth Alexander, an infectious disease expert at the University of Chicago.
  • "I continue to be amazed that people bring this issue up," said Paul Offit, a pediatrician and noted University of Pennsylvania vaccine researcher. "There have been six exhaustive studies (of a possible link between thimerosal and autism). ... They each came back with a definitive answer: No. Three other studies were done to see if thimerosal caused any signs of mercury poisoning. All three answered: No."

    Salmonella and Campylobacter are the leading causes of food borne illness. It is on the rise for resistant bacteria to be within food, so doctors can not treat the bacteria properly. Cleaning food is essential, but this not include uncooked meat because the bacteria in the juices could go into hidden places.

    Researchers use bacteria to deliver radiation to shrink pancreatic tumors in mice. This is really cool because I work with Listeria to form biofilms. It is known for causing food poisoning outbreaks from contaminating ready to eat deli meats or soft cheeses in food processing plants, so it is interesting to see a different take on this bacteria!

Discovery holds potential in destroying drug-resistant bacteria - 0 views

  • Dr. Montelaro and his colleagues found that a particular sequence of amino acids on the tail end of HIV allow the virus to "punch into" and infect cells. The team manufactured a synthetic and more efficient version of this sequence -- called engineered cationic antimicrobial peptides, or "eCAPs" -- that laboratory tests have shown to rapidly destroy bacteria that are otherwise resistant to most standard antibiotics.
  • Traditional antibiotics typically work by poisoning important metabolic processes after being taken up by the target bacteria, a process that may take hours, or days, to clear a bacterial infection. In contrast, the eCAPs are specifically attracted to the surface of target bacteria where they disrupt the bacterial membrane, causing death within seconds, or minutes.
  • eCAPs work well against biofilms

    very interesting...the same mechanism HIV uses to infect cells can be manufactured and used to destroy antibiotic-resistant bacteria

Disappearing Seagrass Protects Against Pathogens, Even Climate Change, Scientists Find ... - 0 views

  • Seagrass meadows, among the most endangered ecosystems on Earth, play an outsize role in the health of the oceans.
  • The plants also fight disease, it turns out. A team of scientists reported on Thursday that seagrasses can purge pathogens from the ocean that threaten humans and coral reefs alike.
  • But the meadows are vanishing at a rate of a football field every 30 minutes.
  • ...7 more annotations...
  • In one survey, they collected seawater and put it in petri dishes to see if colonies of disease-causing bacteria known as Enterococcus grew from the samples.
  • In a second search, the scientists grabbed fragments of DNA floating in seawater.
  • Water from the seagrass meadows had only half the level of this DNA, compared with water collected at other sites.
  • Reefs next to seagrass meadows, they found, were half as diseased as those without meadows.
  • Seagrass meadows can release so much oxygen that the surrounding water fizzes like champagne. That oxygen might be able to kill pathogens, Dr. Lamb realized. The plants also host fungi, which are known to producing bacteria-killing compounds.
  • Their research points to two main culprits. Eroded dirt washes into the Chesapeake, making the water cloudy. Seagrass get so little sunlight that the resulting dimming can be deadly.
  • Seagrass is also being pummeled by climate change. Warmer summer temperatures in Chesapeake Bay cause the plants to lose much of their oxygen through their leaves. With less oxygen to pump into their roots, they are poisoned by toxic sediments.
