randymarsh Posted May 29, 2017 Posted May 29, 2017 Mentioned in another thread I've been living off pla ra for 2 years in isaan (every type of tam you can imagine, sometimes 2 or 3 a day) without ever googling it to know it kills you. For the last month I've had pain in gallbladder area, nothing severe but general ache, occasional twisting feeling. Could be completely unrelated and probably is. Did have an abdomen ultrasound and nothing found. However, 2 years of pla ra is making me think as a precaution I should take praziquantel just in case. On the dosage, it seems 20mg per kilo of body weight 3 times a day. I'm 88 kilos, so 1,760mg x 3. They come in 600mg pills, so this is 9 pills in a day? Seems a lot and don't want to get this wrong and kill myself. Some of my gfs family self medicate every 3 months, I assume with praziquantel, and there's no way they take that many in a day... Final thing and I might be mocked for this by all the farang who dismiss isaan food and have continued to eat only pie and chips since moving to Thailand but it is ingrained in daily life here and has become so for me too. Is there no hope? Do I have to stop completely, alienating myself from the entire isaan population and being generally depressed at not being able to eat som tam, and all the other amazing food pla ra is used for. Or do I just make sure it's properly prepared? I hear fermented for 12 months minimum is safe and no raw fish floating about. There is no way to know the history of this stuff, especially from food stands outdoors but can I source clean stuff for home use? How about the bottles that are sold in places like tesco, although not as tasty, I suppose it's worth a compromise for safety. Thanks! 1
Popular Post Sheryl Posted May 29, 2017 Popular Post Posted May 29, 2017 The dose for liver fluke is indeed 25 mg/kg 3 times a day for 2 days. So yes, 3 tablets 3 times a day. It is taken in a much lower dose for intestinal worms, but this is the liver fluke dosage. You should really stop eating that stuff. In addition to liver fluke it can transmit Hepatitis. 3
randymarsh Posted May 29, 2017 Author Posted May 29, 2017 Thanks.... would.you say it's worth taking it for 'just in case' measures? Is it generally well tolerated?
Popular Post GroveHillWanderer Posted May 29, 2017 Popular Post Posted May 29, 2017 As far as I know, many Thais are aware of the dangers of eating uncooked pla ra and many of them, especially the younger, better-educated ones, now only use it if it has been cooked properly (boiled, basically). Despite the old perception that uncooked pla ra tasted better, I remember reading an article where blind taste tests conducted by a doctor doing research into the health risks associated with its consumption, found that the tastes of the cooked and uncooked varieties are indistinguishable. 3
randymarsh Posted May 29, 2017 Author Posted May 29, 2017 So as long as I keep on the cooked stuff and I always ask first, I should be ok? 2
Popular Post Sheryl Posted May 29, 2017 Popular Post Posted May 29, 2017 Cooked is fine. But be wary of Thsis telling you what you want to hear rather than what is necessarily true... 9

It is certainly true that Thais are aware of the dangers. There is an education program on this very topic that takes the message out to rural areas and they have programmes in regional hospitals. Our moo baan nurse arranged for residents to attend such a lecture at the government hospital, followed by stool analysis and treatment for any that needed it. But old habits die hard in rural Thailand. One of the folk law rumours is that if you drink Lao Khao with your pla ra, you will kill off the parasite. Phew, what a way to treat your liver. No wonder so many meet with an early death due to renal failure! Back to the OP's queries and not withstanding the local's advice on medication, as I mentioned above you can arrange to have a stool sample analyzed to detect whether you have been infected. Personally, I wouldn't go for self medication without evidence that you are, in fact, infected. That was the advice that my wife and others received during the lecture. Another factor is that you can carry infection for very long periods, twenty to thirty 30 years was quoted without any noticable symptoms, so it is possible the your symptoms, OP, are something unrelated. And I certainly agree with Sheryl's last paragraph. ''You should really stop eating that stuff. In addition to liver fluke it can transmit Hepatitis''. Why take chances with your health? You can enjoy good Issan food without risking your health. 3

randymarsh Posted May 29, 2017 Author Posted May 29, 2017 There isn't too much isaan stuff that doesn't use pla ra... I just went to the biggest facino pharmacy around and they no longer hold praziquantel. They offered me Albendazole instead which has to be taken for 7 days based on drugs.com although pharmacist told me only to take for 2 days. Also isn't the drug of choice for flukes Usual Adult Dose for Clornorchis sinensis (Liver Fluke) US CDC recommendations: 10 mg/kg/day orally for 7 days Comments: Recommended as alternative therapy Any ideas of praziquantel is still available? Seems crazy that it wouldn't be. And on the advice to get tested first, I think I will do. 2 days on praziquantel would have been ok but I'm not taking some random pill for 7 days when it might be for nothing.
Moonlover Posted May 29, 2017 Posted May 29, 2017 I'm coming back in on this, because I've just spotted an anomoly and I'm not sure whether we're on the same page here. OP, you referred to the dish you eat as pla ra. Well, in connection with liver fluke, this doesn't make sense. Pla ra is fermented fish sauce, usually at least six months old. The fish is cooked at the beginning of the proccess. The dish that contains liver fluke is called koi plaa, a salad included finely chopped small fish. If the fish used is not cooked, as is the traditional way, it is potentially dangerous. (My Issan wife is confirming this as I type by the way) Now as I mentioned earlier, my wife is well aware of the dangers of this affliction, but she is very happy when eating pla ra. In fact she loves it. So it could just be that you've got yourself a little confused. You might not be at risk at all!
randymarsh Posted May 29, 2017 Author Posted May 29, 2017 As far as I know, 2 different types of pla ra, used when making all types of tam. One is cooked and one isn't. There is definitely a risk of liver flukes from pla ra used in tam if it isn't fermented properly (for long enough), is not cooked properly, contains raw fish, is not clean... Some food stands have 2 types of pla ra to choose from, one they claim is cooked and another which has very visible uncooked fish floating in it. I stay clear of the second option.
peterb17 Posted May 29, 2017 Posted May 29, 2017 This is madness- you are consuming food that you think may do you harm. The dangers of liver fluke have been known for years- many threads on here. I personally never ever take any type of drug - it's not some fight against big Pharma ( as many feel) Obviously if I was really ill I would take the medication. It reminds me of a friend who constantly took antibiotics ( tetracycline ) - just in case- it's the same here- eat safe food and do not pop pills. Are the from the USA - so many American posters seem obsessed with their 'meds' 1

If left untreated, will cause death in about 20 or 30 years. So why not self medicate just in case? Lots of Thais do it. Tell me how exactly it's better to never take any med until it's too late and untreatable?

randymarsh Posted May 29, 2017 Author Posted May 29, 2017 Cheryl can comfirm but definitely a risk from pla ra and my gf has confirmed the same. She no longer buys som tam with the fish floating in. Not to mention the raw crab in tam pu pla ra which again cause flukes. Koi pla is just one of many many isaan meals that will cause flukes as it contains raw fish.

I'm asking my gf more details now. Pla ra essentially isn't cooked but if it's fermented properly for the correct amount of time, it can sometimes be safe. At the end of the process, ideally 12 months later, this is where the optional cooking comes into it (adding actual heat). At this point, sugar, coffee, or more water is added and heated to make the sauce that is used in som tam. Generally the heated pla ra is used in som tam, the overall ingredients vary the taste meaning some restaurants are more renowned for their tasty pla ra.... but some Thais still prefer the uncooked stuff in their som tam that still has 6 month old dead fish floating about. Not safe!! 1

Plus I'm not completely convinced she knows the full process and its timings and variances. Ok, here goes. The usual fish used in Pla ra, cooked or raw is Snakehead fish or Catfish. Note that both these fish have a smooth, mucas covered skin and, in fact the Catfish is virtually scaleless. Have you ever tried to pick one up? They have evolved that way to facilitate their expeditions across land, which they are both known for. The Liver Fluke's larvae, once it leaves the snail in which it develops seeks a host in the water. Its preferred host is a Cyprinidae. You can look it up if you like, but I'll tell you, it's a large group of fishes that are all scaly. The larvae does not penetrate its host, it slithers under the scales and takes up residence there next to the skin. Because the Catfish and the Snakehead fish, used in Pla ra are smooth skinned, the larvae cannot attach itself to them. Therefore Pla ra is a very unlikely source of liver fluke infection. Do note that the freshwater crabs that you sited. would not be a likely host for the larvae either for similar reasons. The reason why koi plaa is a threat is because it contains small, uncooked scaly fish, with the larvae still attached to the skin. Cooking the fish first is the recommended way to prevent infection. That's it. It's dinner time and I think Catfish curry is on the menu. Yummy! 3
bangkokairportlink Posted May 29, 2017 Posted May 29, 2017 You should only eat Plara made by someone you know or by family. And you should not eat your Somtam so spicy, or at least it it with bread !

"Thais’ love of “pla ra” or raw fish used in somtam, as well as other undercooked foods are responsible for increased rates of worm infections, which can lead to liver cancer. " https://www.thaivisa.com/forum/topic/981687-somtam-slowly-killing-many-thais-cancer-center-says/ "A cross sectional survey on opisthorchiasis was conducted from August to September 1933 in Tambon Nai Muang, Sawankhalok district, Sukhothai Province. The 1,964 villagers were stool examined and it was found that 384 of them had liver fluke infection. Of these 1,608, who were older than 12 years, were interviewed in order to detect potential risk factors of liver fluke infection. The study found that the population at risk were those older than 24 years of age (p < 0.05) and the possible risk factor was eating incomplete cooked fresh water fish (p < 0.05). The food prepared from incomplete cooked fish which was harmful to the villagers were pickle fish so called pla ra (p < 0.05) and papaya salad with pickle fish so called som tam pla ra (p < 0.05)." https://www.ncbi.nlm.nih.gov/pubmed/10774677 3

You haven't particularly corrected anything about the process of making the pla ra used in tam; just claimed the fish used can't cause flukes. Evidence suggests it does (if not cooked).

Recently there a warning from Thai Health about the long term risk of consuming local fish sauce due to the fact that the parasitic and other infections of the liver areapparently involved in the alarming percentage of liver cancer deaths in the Issan area. The commercial brands in Tesco etc are a different safer kettle of fish altogether!
