I'm sick of working on a select agent. Sick I tell you!!!

According to the wictionary, a select agent is a pathogen or biological toxin which has been declared to have the potential to pose a severe threat to public health and safety.
According to the microbiologist xx dictionary, a select agent is a pathogen or biological toxin that, when studied, results in: (1) mass amounts of documentation, (2) paperwork, (3) endless training courses with the safety department, (4) finger printing, (5) inspections by people that were douche bags in a former life and (6) any other kind of treatment that makes a researcher feel like a criminal.
I am in a particularly foul mood about this because my lab just got a "surprise" inspection by the CDC on Wednesday (totally killed my Obama buzz). On the plus side, I did get to meet the biggest tool ever.
Don't get me wrong, I don't mind following the rules, filling out the paperwork or surprise CDC inspections. I know that they are just trying to keep people safe and ensure that we are abiding by the proper procedures. However, I do resent being treated like an idiot by some jack-ass that has never performed an experiment or worked in a lab. But, since he has memorized the latest bio safety bible he can walk around spouting out rules and regulations, crowing and strutting like he could not otherwise do. Grrrfuckingrrr.
During our first CDC inspection, one of them showed up wearing a skirt. A fucking skirt. Who wears a skirt to inspect a lab that requires long pants, closed toed shoes, full length lab coats, gloves and safety goggles to enter? Someone who doesn't have a clue about what they are doing, that's who. (Thankfully, these people weren't inspecting our BSL3.) We spent half the day wondering if it was some kind of test. It wasn't.
Anyway, just when I was getting over Wednesday's inspector douche, I came across this article in Scientific American: "Postal Anthrax Aftermath: Has Biodefense Spending Made Us Safer?"

The article pissed me off immediately with the following statements:
In the past six years, says Rutgers University microbiologist Richard Ebright, “the Bush administration has driven a 20- to 30-fold increase in the number of institutions and individuals with access to live, virulent bioweapons agents,” to about 400 institutions and 15,000 people. Every one of them, he claims, “is a potential source of an attack like the 2001 attack.” Even before the expansion, some 100 scientists had access to the anthrax strain Ivins managed. Moreover, huge growth “multiplies the chance of an accidental release,” argues Hillel Cohen, an epidemiologist at the Albert Einstein College of Medicine in New York City.
Newsflash, every single person on the planet has access to almost every select agent organism. If you can find a map of endemic regions, and you can buy a plane ticket, you too can have your very own select agent. Of course, you might get sick and die without the proper precautions, but you can still access it without breaking any rules. It's like these people forget that the organisms we work on occur in nature and aren't man-made.
Also, I fucking resent being referred to as a potential source of an attack. Not only do I not have a clue how to weaponize a select agent, neither does anyone I work with or have ever worked with. Furthermore, everyone in my lab is approved by the department of justice, so if the labs are full of terrorists, then who is really to blame? Hell, many of these labs are under such strict regulations that they are only allowed to hire people from certain countries.

What about this accidental release referred to in the article? Let me explain why this is highly unlikely.*
In a BSL3, the organisms are only handled in a biosafety cabinet (BSC) which is located within the biosafety lab. The BSC has a small opening along the bottom that a researcher can put their arms through. Cultures, stocks, etc. are only opened within the BSC, which has an upward airflow that is directed toward filters. The BSC and the filters are inspected on an annual basis, just like the biosafety lab itself.
Obviously, humans make mistakes, which is why many precautions are in place for incidents, such as spills, that might occur outside of the BSC. One of the most effective precautions is negative pressure. Since air is sucked into the lab, and not out, the organism will remain inside the lab, even if it is outside the BSC. The researchers are really the only ones at risk if such an event occurs. Negative pressure is so important that panels monitoring the air flow direction are located outside the BSL3 entrance and we check them before we enter. Also, specific procedures and protocols are in place that address spills and other accidents. These protocols are discussed to the point of insanity during the annual safety meetings.
Finally, I would be remiss if I did not mention that special protective clothing is worn within the BSL3 at all times. When we exit the lab, this gear does not leave with us, so if anything were on the outer clothing (which it should not be unless there was an accident of some kind) it does not leave the lab with us. These are just a few of the many precautions we take and it doesn't even include the security measures that are in place, but I think you get the idea.
Anyway, I could go on and on about this, but the blog post will never end. Besides, it's just a matter of time before another article comes out that pisses me off and causes another blog rant. :)

*Keep in mind that I am referring to a BSL3. A BSL4, which typically contain organisms that are more virulent, have many more levels of safety precautions. Also, precautions taken within a BSL3 will vary by organism. Some of the measures I mention are general safety precautions which typically serve as a starting point.

Watchdogs...ruff

I am not against government or agency watchdog-type groups. I think the majority of the time we are better off for them. Accountability is a strong motivator to do the "right thing." However, I think some of these groups could do more harm than good.

For example, the anti-vaccination groups.
I think these people mean well, but people that understand how vaccines work and can critically think about scientific data, know that what anti-vaccine pushers are saying doesn't really make any sense. I don't want to go into too much detail because I think that Dr. Steve Novella does an excellent job of explaining the errors and misconceptions of the anti-vaccine movement on his NeuroLogica blog. These groups have been in the news touting their belief that vaccines are to blame for the increases in the number of children that are diagnosed with autism. Originally they proposed that thimerosal (an organic mercury compound) was to blame. Recent scientific studies show no connection. Furthermore, despite removal of thimerosal from vaccines, autism cases have continued to increase. Still the anti-vaccination movement persists.
The major problem here is that these groups might (and one might argue, aim to) encourage parents not to vaccinate their children. Even a small decrease in the percentage of immunized people in a population can seriously compromise herd immunity. If you are immune compromised (cancer, transplant recipient, elderly) herd immunity is vital.

Example 2 (a group near and dear to my heart): The biosafety or biosecurity watchdog organizations.
These groups might obtain information (like meeting minutes) under the freedom of information act and then compare these minutes to incidents reported to the CDC. If they find an incident mentioned in a meeting, but not reported to the CDC, the group reports the lab and institution to the CDC and the media. There are serious consequences to not reporting incidents.
My lab includes a BSL3 laboratory and we work on a select agent, so any type of exposure to the organism, whether it is actually putting someone in danger or not, is written up and reported. Additionally, whenever we use the bacteria, we record this activity (in detail) in a log. Fine. No problem. (I'm not even going to get into all the security precautions we take. This is another blog entry on its own.)
What irritates me, is when a watchdog group sees that an incident (that was reported to the proper agencies) happened within a BSL3 or BSL4 and decides to send out press releases to the media painting the incident as a near catastrophe that puts the publics health at risk. I read one news article where a watchdog group member discussed the problem of "rogue" labs within the US that are working on select agents. WTF is a rogue lab? Is it in a motor home with foil over the windows like a meth lab? Where is this "rogue" lab information coming from? If they know of them, why aren't they reporting them to the CDC?
In other articles, I have seen these people describe the number of reported incidents that occurred within BSL3 and BSL4 laboratories. The numbers might seem high, but they are not discussed with any context. This number doesn't reflect safety unless you compare it to how many times a lab member does an experiment in a BSL3 or BSL4 lab without an incident occurring. Of course, we don't have to report that.
Let's think about this for a minute. People are going to make mistakes and have accidents. It's fact. This is one of the reasons why certain research is done in a BSL3 or BSL4 environment, and not in the hallway of an elementary school. The accidents that happen within a BSL3 or BSL4 laboratory are already contained by virtue of where they occur. The only people exposed are those within the lab itself. Even so, the lab members (if following proper protocol) should also be safe in many of these scenarios because they are wearing protective clothing, face protection or are vaccinated. So, if you hear about an incident happening within a BSL3 or BSL4 be glad, that is where it is supposed to occur.
Personally, I think it is unethical to scare the public when there is no real danger.

The point? If you are going to guard the public from harm and are concerned about peoples health and well-being; great. Just educate yourself first so your advice or opinion is more likely to help.
