is techno a show about innovations that can change lives the science of fighting the fire we're going to explore the intersection of hardware and humanity and we're doing it a unique way. this is a show about science blow not nice scientists. tonight techno investigates shrimp safety the seafood by nature is a high risk commodity for americans love their shrimp but most of it comes from countries that use expensive antibiotics that could make you ill now techno goes inside the federal testing program american food policy. that's supposed to protect the food supply doctors should do some more is mechanical engineer she will share the results of her investigation to how dangerous is that for human beings and i'm

filled torahs i'm an entomologist visitor shrimp farm in the middle of indiana yes indiana that could revolutionize the industry well this is like a little laboratory here yes it is an issue for a terrorist santa maria it is a neuroscientist. imagine that you are one of the 1st to take a trip to mars. this is the definition of pioneering that's what makes it exciting that's our team now let's do some science. yes sir. hey guys and welcome to techno on phil tours joined by dr shinee so mara and cara santa maria because i'm not going to live one of my favorite things is shrimp sizzling away on a hot grill but i also have a fair amount of hesitation when it comes actually knowing where that shrimp comes from and you may not realize it but shrimp raised over seas can have high levels of

antibiotics and other additives that don't always. american safety standards and america imports a lot of shrimp over a 1000000000 pounds worth so we asked the food and drug administration the agency responsible for policing u.s. ports if we could follow them while they test for unsafe shipments. america has a jumbo appetite for shrimp it's a little piece of flesh that they could eat see it's kind of like popcorn of the sea americans it's an average of 4 pounds pop passes. at fred $62.00 and no sanjay's chef eric serves a lot of shrimp it's very difficult as a chef or restaurant or to buy shrimp with the confidence that what you're serving them is going to be good tripod right which. americans taste comes with

a price. 90 percent of the shrimp eaten in the u.s. is imported. much of it from countries like india thailand and indonesia sometimes trip is raised overseas using production drugs like antibiotics that are approved for use in those countries but not approved for use in the u.s. johns hopkins microbiologist david love surveyed federal data on drugs found in imported shrimp some of the top drugs that we found in shrimp were i'm sure if you're and chloramphenicol tetracycline itself on a meds and instructor meissen what does it mean for the consumer to be exposed to antibiotic resistant bacteria if you get an infection from these bacteria it can be hard to treat using antibiotics especially if these bacteria are resistant to the antibiotics that your doctor would prescribe the shrimp farms that use antibiotics often farm with overcrowded pom's diseases are a big deal in term farming can be

a high mortality rate. farms. the food and drug administration polices shrimp imports. $5500000000.00 pounds of seafood is imported into the united states every year and much of it ends up in a cold storage facility like this one in southern california but only a tiny fraction of all of that seafood is actually inspected so we've come here today to find out exactly how the f.d.a. does. emily morrison is a veteran f.d.a. inspector collected one subsample out of 15 random boxes and now i'm in the process of bagging them. put them in coolers.

and ship it to the lab a computer system red flags imports believed to pose the greatest risk based on country of origin and the company's past history of violations seafood by nature is a high risk commodity dance elise has inspections at the ports of los angeles so there are many boxes here and there or packed full what percentage of the sample gets chosen to be taken to the lab so reviews of electronic transmissions we utilize things like foreign inspection domestic inspection whether it was sample than another all that information is gather within the predict application and then that shipment will be given a risk or the higher the risk or the more chances one of these officers will sample that. once the f.d.a. inspector picks samples for inspection is sent to an f.d.a.

lab like this one in california. you may be assured they are getting all. i can imagine. but the ship is mixed with a chemical solvent dried and liquefied again run through an analyzer. is an f.d.a. chemist the results are written from the tests what are they showing us in this closed the compound working for sponsored programs and how dangerous is that for human beings virtual current is dangerous for human beings because this costs so much. for nerves or for this hour the building of one cause the building of this equipment to work in one so. good sized swimming pool so how many parts per 1000000000 is this result i was 100 troops building so

2 grains and so in the olympic sized pool when you've managed to find it out by now that's incredible so that batch of strength is not allowed in this country is this not going to be how long does the f.d.a. simply isn't testing enough on the imported market to really find all of these violet of residues dr rangan had a study of imported shrimp for the june 2015 issue of the influential magazine consumer reports of the $205.00 imported farm samples that we found a leaven of those actually had illegal residues of antibiotics on them and that comes out to about 5 percent of the imported farm shrimp samples being contaminated with an illegal antibiotic residue the fact that the f.d.a. only tests about point 7 percent of all the shrimp in this country for those antibiotic residues suggests that the agency is not actually testing enough shrimp

to catch the amount of week old residue products that may be coming into the mine. however many of the countries that export the shrimp permit the use of antibiotics when you feed low levels of antibiotics every day you're not feeding them enough to necessarily kill bacteria those bacteria can become resistant to those antibiotics and that can make those antibiotics less effective in people if we're infected by those bacteria just as worrisome was the number of shrimp that tested positive for bacteria we found about a 3rd of the shrimp that we had had vibrio contamination vibrio is one of the few food borne illnesses on the rise 7 of the samples we found had mercy that's concerning too and that's probably primarily associated with the amount of processing that goes on the shrimp production both have the potential to cause illness through the cooking process they can be killed we do know that there are shrimp farms and shrimp production practices that are doing

a lot more to address those issues that are addressing hygiene and addressing other issues so that they aren't heavily reliant on drugs or other chemicals. 600 miles from the nearest ocean. patchwork of windmills and soybean and corn fields the tiny indiana home to. a mom and pop indoor salt water shrimp form. their own their over want to know welcomed r.d.f. travis county. dear old brown accidental shrimp farming pioneers now at 6 pounds with $32.00 dozen basic backyard pools as growing tanks the perfect indoor system with 0 waste no chemicals in the 90 percent survival rate. that's a 3rd higher than traditional outdoor through farms well this is like

a little laboratory. form yes we do 90. yes every single day we do temperature design oxygen night shite c o 2 salinity alkalinity ph ammonia and flop as you can see our water is brown the test we're doing here right now is we're trying to see how much bacteria is in our water and we call the settling so you're basically waiting for all this bacteria to go to the bottom and that tells you how much is in how much we have an exact like air for over a certain level then we have to get it out of the tanks otherwise it's going to start suffocating the strap that's very important that has to be done every day basically we're not even farmers anymore we ask ourselves guardians of water as long as the water does what it's supposed to be doing the shrimp do just fine we add no antibiotics no hormones are ever added into our tanks you heard that right no antibiotics no hormones just fish food salt and baking soda it's called federal troops with bio flux system a process that revolves around bacteria no it looks very room what is this room

that i'm seeing the ground is the bacteria and the bacteria is why they sell their way so that they can survive without a major filter here's what's happening below the surface the shrimp eat their feed in excrete demonio the bacteria turns that into talks ignite troitsky other bacteria turn that into benign i treat and as the waters air raided the nitrates turn into a harmless gas and around and around how long have you had this water for years and how does it compare to other short forms most of don't have water that law we by mistake actually kept our water it's like it's maturing it's like one yeah and we just found out that the older it gets the better it gets and so too for the shrimp the growing process starts every month with about 250000 newborns cold post laurels nicknamed. now we're going to show you about r.p.'s and when they come in they're the size of an eyelash so it's hard to see inside this water but how many shrimp

are actually in here we've stopped about. 17000 each one of my 6 tanks there so what are all these tubes coming down those are airlines that adds the oxygen and their oxygen and keeps everything in suspense in because if this stuff settles i'll have 20 minutes and then 20 minute by minute maybe that everything here seems so precise it has to be it's mother nature will it is mother nature but with a lot of help from a mother in indiana i notice there's foam on top what is this foam foam is mostly c o 2 mixing with their feed that just comes to the top and it will actually disappear so it's part of the process is part of the process. yeah it's wrong. because. this is what you see in the supermarket when you get assurance now as i said they can be frozen with a hat on they're very translucent and one of the characteristics we actually look

for my eyes see the long intent is that tells me they're happy. in their intent as a short they're fast now every good see here this is their only protection and these mad right now that mouthpiece have these very angry at me from as well horn yeah that if you can look right where your thumb is that that's where part is also you can see it start being. a month later they're promoted to the production team with the turn in to dinner there are. 40 after you know you have to keep going do it after. you get sick. or you say a number of beds are brown so about $500.00 pounds directly to walk ins each month at $18.00 thank you very much i did thanks they. told their know how to do 2 dozen start up forms in the us as well as ones in switzerland heating in spain

these companies are really innovators they're trying out new technology johns hopkins microbiologist david love. dirties true production he gives the production like the bronze a high grade with one kind of yards one that could ultimately make or break in the business world a lot of these farms my start out with a bang but then fizzle after a few years because they don't make money for the browns shrimp farming is paying off no financial fees will only sizzle as the business continues to grow is it really is just a bad but the proof of their success is what ends up on the plate in this case innovation tastes pretty good when served with the profits that are so good. i still can't get over the fact that possibly the cleanest and arguably the best shrimp in the world may come from the middle of indiana so i guess i'm. in the

table looks a little gross i get that but it's chemistry in there and good in results is really good there's a global problem with using a lot of antibiotics in farming the more antibiotics used the more we're going to start seeing antibiotic resistant superbugs it happens in agribusiness here in the us it happens overseas and it even happens in medical practice you know a lot of people ask why should we care if there's some superbug that can infect shrimp how does that affect us but what they found is that bacteria can actually swap genes so potentially if the bacteria that infect shrimp becomes resistant it could swap the gene into a bacteria that infects us and so that resistance me passed on and the amounts of you know millions of pounds of antibiotics are being used around the world not just in trim but in cattle and poultry as well that is going to catch up to us when it hits our health care system that it's called a it's called a spillover event it's not infection it's an infection that happens in an animal

species and then just like that a human can get infected to and it's been the source of most. most deadly diseases that medicine can't keep up with and that's where you look at the numbers care we have a 1000000000 pounds getting imported here only 2 percent actually gets inspected what about the other 90 percent it's important to have confidence in this system moving forward if we're going to keep eating shrimp and the inspection process the same brand i mean the amount of shipped in that came investors will actually made it into a lab is tiny tear what you have coming up for us next you have really interesting story now imagine that you are one of the 1st pioneers to take a trip to mars but also imagine that you're not allowed to come home it's a one way trip which you guys do at. i met a woman who is already signed up and she's raring to go. for decades humanity has been fascinated with a manned expedition to mars. this is. the definition of

pioneering. that doesn't scare here that's what makes it exciting robotic pioneers like mars curiosity rover have been crawling around the cratered landscape uncovering clues. about whether this distant planet can sustain life as we know it do you have the right stuff have the right stuff jamie del rosario is a 27 year old entrepreneur and c.e.o. of the international metal stores a raw materials company that supplies metals to aerospace companies like space x. and lockheed martin she is one of 100 candidates that has been selected by mars one a private company that wants to colonize the red planet the catch there's no return flight home what do you say to people when they say jamie this is a suicide mission why are you doing it call it as i said mission but it's something that i chose i'm creating my own destiny for myself and and if it's

a destiny that would help humanity. i'm all for it. according to mars $11.00 of the main goals of the project is to establish an interplanetary species to preserve the human race. i want to contribute directly to mankind's call for the expansion of the solar system which we have to the 4 point destroyers in the world she made it to the top 100 the 3rd round of the selection process mars one says started with 200000 online applicants ultimately $24.00 crew members will be chosen. do you think that anybody with enough training could be. common astronaut i believe that if you have. the motivation and it's terminations of wanting to do it you can a mission to mars is obviously no simple matter pasadena california is home to the

mars program at nasa is jet propulsion laboratory nasa has taken the man to the moon and back but they've approached this journey with a much more deliberate and rigorous training program. i'm now on the base on mars and i will give you a little tour in 20156 volunteer scientists walked out of a dome on the side of a hawaiian volcano after being locked away by nasa for 8 months this was a simulated experiment of what life on mars would be like coexisting is one challenge getting there and surviving is an entirely different endeavor landing on mars is still pretty well sometimes it can be quite a terrifying play. dr richard zurek is the chief scientist for the mars program at nasa as jet propulsion laboratory a lot of things have to happen right right know we fly into the atmosphere we have would he choose the protection but we're also trying to slow down so that we can

land softly. we're talking about a very different scale of endeavor we're landing a metric ton down on the planet today we think for human missions to get stuff down on the surface that they can use that they can be there for a long period of time that means 4050 metric tons that's a lot of material today we don't know how to land on mars one has come under critical fire for their project primarily due to funding issues and for reports of recording the mission for reality television show. in march 2015 c.e.o. basilan store took to you tube to respond they are currently selling our documentary series to international brawls costs or there's no deal in place yet but it's looking very promising there's a lot of interest when we really fell you are good criticism about our mission

because it helps us to improve our mission also tells techno quote there are less serious critics who are only interested to sabotage our mission for example by lying but even if. this nonprofit's mission never launches nasa is laying the groundwork today this is very much in the mode there are going to be humans on mars we're in the 1st stages of trying to understand what it takes to actually be able to explore with humans on the surface of the planet we've made a good start for everybody program 1st it's to get down there see what the planet is like if those 1st explorers out there on the surface in that we can see what the future holds not in a 1000000 years but i want to go and colonize mars i mean there's so many risks it's so frightening to me what is the value that's different from me and probably from most of the people living on this planet who are afraid to go some people just have different goals and missions i want to do something that would change the

world or help the world so if you are selected to go to mars do you foresee yourself getting married on mars having children i'd say that. is you know interesting because it will happen do you think that's going to be a part of your training i would think so i mean that's something that we cannot shied away from because we're the new frontiers of calling me and i think another part in the solar system are you scare leaving earth behind i will miss it everybody is trying to get to mars and i think what stands out with my swan is a permanent settlement and i think this is the time now. so i'm really interested you guys would you sign up for a one way mission to mars i wouldn't you wouldn't mind where i am i would possibly but i don't think i would sign up for this one way mission the mars jewelers through history so many pioneers and explorers were to be fair a little bit crazy and sometimes they succeeded but other times they didn't but it

always will push progress forward just a little bit through how i think the merit of this project is the fact that they go lives to try to be able to to achieve living on mars and the result of having a go at night which is extremely ambitious is the amount of technology that's going to be developed you know just crazy inventions and innovations that are going to come out of a kind of pie in the sky it's relative you know i think we've talked sustaining life on other planets versus sustaining life here on earth is really interesting topics today guys so thank you for them we'll have a lot more of these stories next on here in techno we'll see you then. we're talking about ivory poachers who have decimated populations of elephants in africa they almost always ship the ivory out of a different country from where it was poached because that's where you start your

search to look in the wrong place this radiocarbon dating method can tell us if trade of ivory is legal or not then we have a place we can focus law enforcement on take those out and perhaps choke the source of the id from entering the network take no one else is there. another early morning another ceremony to bid health workers better well. 29000 to cuban doctors and nurses working in 59 countries around the world has confirmed cases of coronavirus increase so does demand for cuban medics medical services and the island's main export while western commentators assume cuba send still has mainly to expand influence experts on the on its health system draw a different conclusion you're making a big sacrifice why are you willing to go. because there are other people that need many people that is sick and dying and not isn't right people shouldn't be dying when there are people who can help them. on counting the cost the pandemic
