shot dead along with her drive on wednesday in what investigators are treating as a targeted assassination. you are seeing with the headlines on al-jazeera the news continues right after technical to stay with us. a global economic superpower that's underperformed in the world of football when he explores how china is now spending billions in his quest to conquer the beautiful game. at this time on al-jazeera. this is techno a show about innovations that can change lives the science of fighting wildfires 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 the ice 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 extensive antibiotics that could make you ill now techno goes inside the federal testing program american food. 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 visit a 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. a terrorist santa maria it is a neuroscientist. imagine that you are one of the first 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.

hey guys and welcome to techno on phil tours joined by dr shannon so mara and cara santa maria because i'm not going to live one of my favorite things is shrimp soon . away on a hot grill but i also have a fair amount of hesitation when it comes to actually knowing where the truth comes from and you may not realize it but shrimp raised overseas can have high levels of antibiotics and other additives that don't always pass american safety standards and america imports are not a billion pounds worth so we are also the food and drug administration the agency responsible for policing us ports if we could follow them while they test unsafe shipments. america has a jumbo appetite for shrimp it's a little piece of flesh that they could be easy it's kind of like popcorn of the sea americans it's an average of four pounds high passes.

at fred sixty two. chef fred eric says a lot of 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. ninety 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 fewer and then i call tetracycline solve on

a mids and instruct in mice and 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. to the antibiotics that your doctor would prescribe overseas shroom bombs that use antibiotics after farm with overcrowded pom diseases are a big deal in term farming. high mortality rate. farms. the food and drug administration polices shrimp imports. five point five billion 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 fifteen random boxes and now in the process bagging them. put them in coolers. and shipped 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 they're all packed full what percentage of the sample gets chosen to be taken to the lab so f.d.a. reviews all 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 much of. once the f.d.a. inspector picks some pills for inspection they're sent to an f.d.a. lab like this one in california. you may see a shrimp maybe only. i can imagine. that the sugar 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 post the compound working for sponsored programs and how dangerous is that for

human beings virtual current is dangerous for human beings because it's costing the . earth. before now so for. the building of one cause we're building this equivalent to avoiding one so. good size. so how many parts per billion is this result i was one thousand troops building so two 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 along with 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 two thousand and fifteen issue of the influential magazine consumer reports of the two hundred five imported farm samples that we found a leaven of those actually had illegal residues of antibiotics on them that comes

out to about five 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 seven 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 residue products that may be coming into the market 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 third of the shrimp that we had had vibrio contamination vibrio is one of the few

food borne illnesses on the rise seven of the samples we found had mercy that's concerning to you and that's probably primarily associated with the amount of processing that goes on the shrimp production both have the potential to cause illness to 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. six hundred miles from the nearest ocean. windmills and soybean and corn fields. home to. mom and pop indoor salt water shrimp for. their own they're over the last time i know welcomed r.d.f. stratus. dear old brown accidental shrimp farming pioneers

now at six pounds with thirty two dozen backyard pools is growing tanks the perfect indoor system with zero waste no chemicals in the ninety percent survival rate. that's a third higher than traditional outdoor shrimp farms well this is like a little laboratory here yes it is in the shrimp form yes it is we do nine tests every single day we do temperature design oxygen night shite c o two salinity alkalinity ph ammonia and flop as you can see our water is brown the test for doing here right now is we're trying to see how much bacteria is in our water and we call this settling so you're basically waiting for all those 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 trap 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 trick to 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 salts and baking soda it's called head root troop 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 variants into benign i treat it 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 now does 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 two hundred fifty thousand newborns called post large bulls nicknamed. now we're going to show you about r p l's and when they come in they're the size of an eyelash so it's hard to see inside this water how many shrimp are actually in there we stock about seventeen thousand each one of my six tanks there so what are all these tubes coming down those are airlines that adds the oxygen and their oxygen and keeps everything in suspension because if this stuff settles i'll have twenty minutes and then twenty minutes i meant 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 now notice there's foam on top what is this foam foam is mostly c o two mixing with their feed that just comes to the top and it will actually

disappear so it's part of the process as part of the process. yeah the song yes. because. this is what you see in the supermarket when you get a shrimp down as they said they can be frozen with a hat on their very translucent and one of the characteristics we actually look for mine see the long and ten is one thousand they're happy. and they're intended to short they're fast now every can see here this is their only protection and these mad right now that mouthpiece have these very angry at me 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 they are. already after you know you have to keep don't do it after. you get sick. or you say

a number of beds are brown so about five hundred pounds directly to walk ins each month at eighteen dollars thank you very much i did think they. devotional sold their know how to do two dozen start up form. in the u.s. as well as ones in switzerland and spain these companies are really innovators they're trying out new technology johns hopkins microbiologist david love studies true production he gives the production like the browns a high grade with one caviar 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 fizzle only says that as the business continues to grow is it already it is that 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 profit motive so you would. know 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 you get some. in the table it looks a little gross i get that but it's chemistry in there and get any 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 that 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 is called it's. call the spillover event it's not a confection it's an infection that happens in an animal species and then just like that a human can get infected too and it's been the source of most deadly diseases that medicine can't keep up with and that's where you look at the numbers can we have a billion pounds getting imported here only two percent actually gets inspected what about the other ninety percent it's important to have confidence in the system moving forward if we're going to keep eating shrimp and the inspection process the same brand i mean the amount of shipping that came investors will actually made it into a lab is tiny care what you have co-wrote for us next you have really interesting story now imagine that you are one of the first 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 to have that right stuff jamie del rosario is a twenty seven year old entrepreneur and c.e.o. of the international metal source a raw materials company that supplies metals to aerospace companies like space x.

and lockheed martin she is one of one hundred 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 one one of the main goals of the project is to establish an interplanetary species to preserve the human race. i want to contribute directly to me in kind of constant expansion of the solar system which will have to go for point destroyed in the long she made it to the top one hundred the third round of a selection process mars one says started with two hundred thousand online applicants ultimately twenty four crew members will be chosen. do you think that

anybody with enough training could become an astronaut i believe that if you have. the motivation and that's terminations of 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 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 two thousand and fifteen six volunteer scientists walked out of a dome on the side of a hawaiian volcano after being locked away by nasa for eight 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. can be quite

a terrifying. dr richard zurich is the chief scientist for the mars program at nasa's jet propulsion laboratory a lot of things have to happen right right know we fly into the atmosphere we have would look for total but we're also trying to slow down what we can while. 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 forty fifty metric tons that's a lot of material today we don't know how to land the 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 two thousand and

fifteen 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 at mars when we really fell you a good criticism about our mission because it helps us to improve our mission also tells tecno quote there are less serious critics who are only interested to sabotage our mission for example by lying but even if this nonprofits mission never launches nasa is laying the groundwork today this is very much in the mode of there are going to be humans on mars we're in the first 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 on a robotic program first it's get down there see what the planet is like pulls first explorers out there on the surface in the we can see what the future holds not the

million year 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 stay there to half isn't 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 shine away from because we're the new frontiers of colony and i think another plan 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 know where i would possibly but i don't think i would sign up for this one way mission the mars jewellers 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 the goal lives to try to be able to to achieve living on mars and the result of having a god like that 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 your doubts have you know i think we've talked sustaining life on other planets versus sustaining life you're wrong earth's 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 dive deep

into these stories and go behind the scenes at the al-jazeera dot com slash techno all in our expert contributors on twitter facebook instagram google plus and more. we're talking about ivory poachers who have decimated populations of elephants in africa they almost always shipped the ivory out of a different country from where it was poached because that's where you start to search for looking in the wrong place this radiocarbon dating method can tell us their trade is legal or not then we have a place we can focus law enforcement on take those out and perhaps the source of the id from entering the network take no at this time in n.z. a myth.
