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 a federal law was passed that required all private keepers to stock their own antivenin, what would your reaction be?

ANTIVENOM
|
have collected, cought, and kept venomous herps for years. before lacey, esa, and plane hijackings (mainly to cuba), could actually bring on board.
now keep south florida species for educational demonstrations, no longer handle or extract during such demonstrations and have a number of heloderma
years ago, anti- venom was not that expensive
obtained through wyth labs and for the real exotics, got from jack facente. today southeast florida has venom one with firefighter and reptile envenomation expert, al cruz
it is incumbent on all of us who keep these animals to do so safely. as for the permit rate increase, yes it should have been raised;however the amount of the raise is absurd; especially for someone as myself who also is permitted for class one, two and three wildlife in the state. i pay the same for my big cat permits as a facility that takes hours or even a day to inspect while it requires just several minutes for me. i am now paying $450 per year for all state permits.
have never suffered a bite. dry bites and near misses dont count. have been somewhat stupid regarding my gilas. first bite caused pain and swelling of hand and arm up to elbow. stayed in touch with george vanhorn during night, just in case. second bite caused same, however just hand with pain and swelling not as intense. there won't be a third. then again, there wasn't supposed to be a first or second.
even though i am winding down, i support the right of others to keep such animals. there are too many who would deny us that right.

This is the first time I've visited this website. I found it searching for breeding info and this question is was to controversial to pass up. I live in Florida and have the licence required by our state to posess venonous reptiles. The cost of that license increased this year from $5 to $100. The fee hasn't increased at all in several decades but I feel it was very overdue. I only bring this up because I know there are a number of states that have no permit requirements regarding venomous reptiles. Because of the obvious malpractice lawsuits that come with someone showing up in the ER with their own AV, there is no way private AV supplies would ever work. I feel that every state should have a license requirement that includes a cost of an AV bank in that state. It would eliminate the problem of compliance and should reduce the cost of the AV itself being an actual gov't entity. Just my opinion. By the way, if anyone has tips on breeding Aspidelaps I would appreciate the help.

Well, if they passed that, it would be a very good way for the government to destroy the the venomous herp world without much effort because very few could afford it. Forums would disappear, classifieds, the sale of books, ect.

people should do it anyway

I agree with the prior statements regarding having your own A/V. I cannot see anything but the obligation of an owner to provide for the "mishappenings" that may result from thier keepings. Its an individuals obligation to be "responsible" for thier "pets." Dogs get rabies vaccines so they can help thwart dangerous "mishaps", so why can owners of v.-snakes carry thier own or at least be responsible enough to provide some type of A/V precaution.
I wonder how many people currently owning venomous varieties even carry thier own A/V now? Or, how are they handling the concerns of bites?.... relying on local zoo's A/V stocks?

just a quick word

I believe that if you want a venomous snake or other reptile you would have to go by the law. its simple enough, pay the cost of keeping a reptile or get rid of it. myslef i own 5 snakes, none of which are venomous. but if one day i chose to own one i would want to have some antivenin around, just in case.

3 Arguments again private AV
|
1. It is over expensive
2. Expiry of AV
3. In case being tagged, you carry you AV to the Hospital, and they deny the Application with the Argument, that they cannot be sure, if it was stored according to the manufacturers manual.
And this is more likely to happen in the US, because everyone with responsibility there is allergic to Law suits.
The only way, is, as I said, you ppl have to found a Serum Depot...

Cost
|
provided the government supply the antivenin, as the lovely horse serum deemed CroFab is fairly expensive judging from my recent hospital visit, in and around $800/vial, average required dosage being 8-20 vials...that's a little pricey, but my love of reptiles is well worth it

Just a thought
|
I would never recommend that someone openly break the law.
I think requiring people to acquire their own supply of exotic antivenins makes sense. Antivenin for indigenous snakes could certainly be expected to be held at the local hospital (albeit the expense could be quite high). However, from what I have heard and researched online, antivenins for exotic venomous are mostly made in countries other than the US and their cost is much less). Perhaps a system could be arranged through one's personal physician (or local hospital) whereby they kept onhand antivenin for the species that one keeps, bought and paid for by the individual, but in the hands of the medical professional in the event of crisis.
Just a thought.

All I can see...
|
.....are millions of lawsuits drawn up and driven home by
morally lax trial lawyers.
But have no fear. The ignorance of the public will ensure
that none of us in America will be allowed affordable
access to any venom for any exotic that we might keep.
Which is why I, a starving college student, keep only a two
year old python and lots and lots of mice. Some day I
hope to own a Bushmaster [if only to taunt my Democratic
friends]. And a Hagen's Tree Viper. Just to thwart the
burgulars.

Add on to Serum Depot
|
1. Sorry for posting the prior Comment 3 Times. I guess that was the Cyber Space Echo...;-)
The Serum Depot is in Berlin, and the annual charges are 250 € (Euros)
The Idea is, that you register yourself, and your animals. In case of an emergency, they provide the appropriate AV for Free. But everyone, who get bitten , has to underdo an allergic test to Horse proteins, prior to AV application.
Maybe, this is an Initative, what should be applied to the US as well.
This Serum Depot is a non-commercial Institution, established by the Herpetological Society.
This Depot could be established in a central hospital pharmacy, which has 24-7 service anyway.
Remember, together you are strong.
If anyone needs more Information about this, please contact. I will provide necc. Infos.
(Btw, everything from Germany is good, except that Stuff what doesnt work.)

Serum Depot
|
Hello Friends,
we have in Germany Serum Depots, which any Reptile keeper can join in, as a Club Member for a monthly fee. This Idea could surround any law restrictions in the US. Unless the Law says, exactly in what distance to the Animal the AV has to be stored. One Serum Depot per US State on a Hospital with an Helicopter base, should be appropriate.
Maybe I invented the Wheel just new, and you people have this kind of faccillity allready.

Antiserum
|
A law like this would be hard to pass and the lawmakers would just outlaw all venomous.
Much easier for them to enforce.
Having your own antiserum would go a long way towards showing that you are a safe keeper. But a permit system like Florida and requiring that all keepers have antiserum could be away of self policing to head off total bans on venomous.
Cost should not be a factor as it is part of owning the animal. If you could not afford to feed them you would and should not have them. Same is true with antiserum. Crofab is expensive but there are other antiserums available for exotics that are not.
Antiserum banks within one hour drive time could help keepers cut costs. To much delay in getting antiserum can lead to organ damage and death.

Anti-Venom
|
I fail to see how a Law such as this could pass! There are far to many veriables, Such as the cost,Crofab can run as much as $1.500 per vial, and the usual dose is six (6) for a respectable envenomation. And that is only for our north American vipers. #2 would be having an allergy to the Drug. #3 would be the rout of administration I M would be out so you would have to learn the proper tecnique for starting an I V line, Who would teach those willing to do this. #4 All drugs have an expiration date and this could be cost prohivative. And the list goes on. No I feel that sooner or later some Moron with a Hot Rep. will do something realy Stupid and we all will have to pay for it.

Here in the peoples republic of Canada, we need health Canada's permission to bring in antivenin made in forgin countries. I have contacted them 3 times to find out about getting the south African polyvalent, but they will not reply to me. My doc will write a script and the drug co will send it but they need to sign off on it first. I figure if I was to get bit they have established a severe liablity for themselves.

i can understand that some people dont bother keeping their own A/V because they only keep native species and their local hospital should stock it anyway. but if someone keeps exotic species then it should be their responsibility to stock their own and not rely on other sources like zoos. the other places stock thier own exotic A/V have it for thier own keepers and it is not their responsibility to look out for hobbyists.
Hotvenomgirl, A/V takes hundreds of milkings and normally numerous venom donours are needed. after the venom is collected it is used to make animals such as horses immune to the venom by injecting non-lethal doses into it. after it build us a immunity the antibodies are taken from the blood and are procesed into A/V

Very simply speaking Anti venom is something that you have to apply for the appropriate federal permits, and order from the country of origin of the species you keep. It most definitely is NOT something you extract venom from your own snakes and make at home! It is something that people do for a living professionally and scientifically in a very controlled laboratory setting!

Survey question..
|
If this did ever come about, which I hope it doesn't, I would do what I could to obtain my own AV. Although another way I look at this is.. Getting AV you have to milk the snake. I don't think I want to be that close to the snakes mouth. That would be in my mind, more of a chance of me getting bit other than just simply keeping my animals. Do you not agree? If someone has the passion to do that (milking a snake) for a living then I personally think let them get that close. If that's their choose of what they want to be then why can't we obtain the AV that way? Isn't that the reason those people have that type of career? Anyways, that's just my opinion, as I'm sure we all feel very differently about this subject!!
Thanks,
Shauna

Absolutely, I would keep my own exotic AV regardless if it were required by law or not. I am working on acquiring my import permits as we speak. Now I probably won't stock CroFab, because it's ridiculously expensive and where I live, readily available. I figure that if I get bitten by a N.A. crotalid, I'll be getting the antivenin at the hospital anyway, so why stock it? Now exotics are a different story, and I'm not going to take precious AV from a zoo or private individual to cover my ass!

I have a company in So.California that offers assistance to the public in safe, sane removal of unwanted Pit Vipers from their property. The Fire Department has contacted me in order to utilize my service, but there are no permits availiable for me to aquire, thus on the table, they cannot formally authorize me. I am working with the Cal. State Fish and Game Commission to rectify the regulations and save untold millions to the taxpayers. With a little effort, my temporary captives might be milked several times prior to release back into the wild, and the eventual cost of finished Antivenin might be substantially reduced. Good Idea?

Cant afford the vials, maybe I'd slim down my collection a little to one or 2 hots, but overall, I think the trade would simply move underground and become similar to the way marijuana is hobbied.
With vial purchases would have to come certifications and EMT courses because of anaphalactic shock and all the peripheral situations that stem from being bitten by a venomous animal. It's best left to the people who are trained to administer it. Im NOT saying however, every doctor at your local clinic knows what they're doing when they treat a snakebite.
Just my a.d.d. 2 cents

Absolutely! No question about it. AV is a must for all venomous snake keepers. It's just not right to ask for (or take) Av from a zoo or private person who has gone through all the trouble and expense to get it. Besides most exotic Av is less than 100 dollars per vial! So a little self regulation would be in order..If I couldn't afford to buy my own, I wouldn't keep that species and potentially rape a zoo or private persons stock, thus endangering their lives!!!!

Federal law to keep antivenin, whats next?
|
In my mind i wouldnt spend the money required to obtain antivenin. I have heard that even for some of the native species prices can run up around $2,000 a vile, I dont know if thats right or not but if it is my lord only the money makers will be able to aford keeping antivenin being the stuff only has a limeted shelf life. Well if i had to i would try but lets hope no such law is inacted......Happy herping Wally
