Current Survey Question
Should hobbyists ever free handle venomous reptiles with their hands?
Recent Surveys
Most venomous/toxic Naja species in the world? I have read that the Philippine cobra is the most venomous (mice, 0.2 mg/kg SC with the lowest reported value being 0.14 mg/kg SC) (Brown, 1973). I have recently, come across something in the Indian Journal of Experimental Biology (Vol. 30, (issue 12), pages: 1158-1162, 1992) which stated that the LD50 for Naja oxiana was the most toxic/venomous (mice, 0.18 mg/kg SC and lowest reported value was 0.10 mg/kg). Along with that, the mortality rate for untreated Naja oxiana bites are the highest among all Naja species (70-80%). N.oxiana also produced the lowest known lethal dose (LCLo) of 0.005 mg/kg, the lowest among all cobra species ever recorded, derived from an individual case of poisoning by intracerebroventricular injection.
Following N. oxiana and N. philippinensis are N. melanoleuca at 0.225 mg/kg SC and then N. samarensis at 0.23 mg/kg. The water cobras (N. annulata and N. christyi also have very toxic venoms, but no SC values are listed. Only intraperitoneal (IP) values of 0.143 mg/kg for N. annulata and 0.12 mg/kg for N. christyi. IP values tend to be generally lower (more toxic than subcutaneous values, so it would be unfair to compare their IP results to the subcutaneous (SC) results of other Naja species. Then I have heard that (without solid evidence) that Naja nivea is the most venomous, although their murine SC LD50 range anywhere from 0.4 mg/kg (Toxicon, Vol. 5, issue 1, page 47, 1967) to 0.72 mg/kg (Australian venoms and toxins Databse).
So which is the most venomous? To me it seems obvious that it is the Caspian or Oxus cobra (Naja oxiana), followed by the Philippine cobra (Naja philippinensis). What do you think or know?
I've noticed that the Australian venom and toxin Database seems to have higher LD50 values for all snakes across the board. For example, for the black mamba IP value of 0.01 mg/kg is listed (http://www.sciencedirect.com/science/article/pii/004101018890219X) and Ernst and Zug et al 1996, list a SC value of 0.05 mg/kg for the black mamba. While the Australian venom and toxin Database listed much less toxic LD50's. So there seems to be a lot of variation.

If you do not have a plan you should not be working with venomous animals. Make sure your plan has a back up plan. Good luck.

okay im new here and have absolutely no experience with hot reptiles...but it seems to me that if you handle hot animals, you should have the fix it within reasonable distance in the case you are bitten...i have always been fixated by snakes, all of them, but i am nervous when it comes to the venom..ive never handled a venomous reptile, because of the swelling i get from a beesting, it probly wouldnt be wise for me..but i want to learn all i can about all these beautiful animals, so if anyone wants to help, id appreciate it..

Ooops, missed one question. I don't think you need to send
any case reports unless you use the av under the IND at
some point. Again, call them! Do as much as you can and
then call them up!

elapidkeeper:
You can put N/A for any of the clinical trials stuff. Yes,
the form is confusing, but it is basically for people who
are actaully going to be trying to bring a new drug to
market. Remember that and either put N/A or 'for
emergency treatment of snakebite only' or some such.
Remember, if you are really unsure, you can always call
them. I've been pretty impressed with them when I call-
even if I have to get routed to the correct person, they
have always been polite, considerate, and patient. They
have always been better than any phone company I've
needed to call!

Kristen-the 1571 form is very confusing..all that phase1 phase 2 stuff,clinical trials...etc,it seems like there's a lot I'm either leaving blank or simply don'T know. I have a cover letter&bite protocols to send...do you really have to submit these and real life instances of usage and the outcomes of the product? I'm so overwhelmed...

Veterinarians can not legally help you get antivenom as
they are not licensed to treat humans.
You want to know how to get it? Here you go:
1. Get a BB-IND number from the FDA, Center for
Biologics Evaluation and Review. Here is their website:
http://www.fda.gov/BiologicsBloodVaccines/default.htm
There is a phone number on there- you may have to go
through a few people, but they will tell you where the
application form is and answer questions. I have never
had them not answer the phone, but sometimes you have
to talk to a few people before you get to the right one. I
think the biggest sticking point for private keepers is that
you HAVE to have a physician be willing to apply with you,
and be willing to take responsibility for the antivenom. If
you don't have a physician or you don't want to ask yours,
you'll have to search for one.
2. Once you have your IND number, you can apply for your
APHIS permit here:
http://www.aphis.usda.gov/animal_health/permits/
It is 16-3 that you use. There is about a $100 fee.
3. Contact the provider and order the antivenom. Both
South African Vaccine Producers (SAVP) and CSL (Australia)
have websites that you can easily google. Thai Red Cross
has an email; email me for it if you are ready to purchase.
4. The provider will send you an invoice. Current costs are
$159 for SAVP poly and $40 for Thai Red Cross, I'm not
sure about CSL but they are typically much higher. Send
the provider the money and a copy of your APHIS permit.
They will send you the antivenom.
That's it. It is not hard, it just takes a while because our
government moves slowly and foreign providers can be
slow to respond. Historically, I've gotten the best
response time from CSL, followed closely by SAVP-they
responded immediatlely this fall, followed by ICP in Costa
Rica (bushmaster keepers take note), followed by Thai Red
Cross-- but even they have gotten better.

Reference Thai Redcross and CSL both can be hard to
contact but we have never had them not take our money. In
fact we are recieving a large order of Thai next week. About
$159. 00 per vial I would say how much is your life worth?
Normally 10 to 15 vials will do the trick. Well worth the price.

BB-IND Permit.

It is close to impossible to talk a doctor into helping you do this these days. They don't want to be possibly held liable or even really understand the forms.At least this has been my experience so far. Also, SAIMR Polyvalent is up to $159 USD per ampule...let's not even get into Thai Red Cross or CSL antivenin who don't even return their emails.

straw man

pictigaster1, your last post is what is known as a "straw
man" argument, and has nothing at all to do with what I
asked...
The survey question is "Do you have imediate access to
antivenoms? If not, what is your plan of action/do you
have one?", I answered "other" as I no longer keep
venomous reptiles, however when I did, it was at a venom
lab (name dropping is rude and unnecessary), we always
kept stocks of antiserum on hand.
As for why my profile is nearly blank, and why I almost
never post on these forums. It is a direct result of
responses like your own.. I'm not on this site very often
anymore due to the arguing and fighting.
My real name up for thous of you who already know me,
and I feel that is all that is necessary, as I do not post
often.
When my profile was complete w/ e-mail (I started
coming here around 2000), I received a great deal of junk
mail, so I removed it
I asked a very simple question. if you don't have "imediate
access to antivenom" and yet you "have a plan" as the
majority of folks have responded (53% as of 2/22), what is
that "plan"?
As Mr. Harrison has previously mentioned, there are a lot
of misinformation floating about when it comes to the
subject of privet acquisition of antivenom, when I was
involved in working venomous reptiles, I have often seen
privet keepers relying on the already meager resources of
zoos and non-profits to keep themselves alive in a
snakebite emergency.
This was my concern when i posted my query...
If such a simple question is to be met with such hostility,
then I shall refrain from using this site any further.
A wise man once said that as a group, venomous keepers
have a job, "we must police ourselves, or this hobby will
be policed for us".
this is why the venomous community is falling apart,
rampant suspicion and unnecessary arguing...
Good luck folks,
TC

Laws do not prevent obtaining antivenom. If you get the
permits you are allowed to obtain and have a doctor use it. It
does take some time to obtain permits but can and has been
done by private individuals. I have had my BB-Ind number
since I was 18 years old. Dr. Minton helped me obtain it.
Alot of misinformation is out there about costs and if private
individuals can obtain antivenom.

You need a choice on there that reads:If it was LEGAL to own your own would you purchase it?
My answer is "yes"
Laws prevent us from owning this life saving serum.
