in the art of climate change. africa. what's in store. for the future. for a game of go sitting. inside. culture. welcome to in good shape. card washing is more important than ever during the coverage 1000 pounds amec but sticking to basic hygiene rules is always one of the most effective ways to avoid getting sick bacteria and viruses lurk everywhere sometimes in unexpected places but not all microbes are bad. hello and welcome to in good shape do you know what those funny birds and me have

in common. on ours surfaces well you think it's kind of discuss thing no it's not because those bacteria are very important for our health and well being and do you know what takes care of all bacteria our own immune system. the immune system we know it as a defense system but it has another much broader function. we end our microbial cohabitants need to be kept in balance exactly how the immune system does that is extremely complicated and we don't yet fully understand it it has to react but without overreacting. it can't just rush in and let fly at random it needs to leave its friends in peace for example microbes which help with digestion manufacture vital substance. says and eliminate pathogens.

but how does the immune system know which microbes are the good guys and which are the baddies. as with every system in the body the immune system has regulators that spurred on or slow it down. our microbial cohabitants help with this fine tuning. microbes convinced our immune system to let them stay they sued it even though it recognizes them as invaders. that's exactly what keeps our immune system in peak fitness it can react quickly to danger but at the same time it's controlled so that it doesn't lash out at everything. as is the case with allergies for example for asthma or auto immune diseases then the body attacks harmless substances or even.

microbes can also defend against pathogens directly. sort of like a gatekeeper to prevent pathogens from entering the body and causing an infection. there is some scientific evidence that our immune system is primarily there to keep our organism in balance with all its microbial passengers the defense against pathogens is only a side effect but an important one. germany goes into the next knock down because of the novel coronavirus and this is why i will continue this show from home. the question what can i do for my personal hygiene is especially important in the times of the new coronavirus pandemic so what to do and what not to do will be the topic of today's top hello today i let's it's a treat for. green you're brilliant and i have to be there with pat. and i

mean. dr sasser was a specialist in hygiene and public health related environmental protection and his particular focus has been on optimizing hygiene in hospitals. hello professor sastra i'm just disinfected my hands it's often said that washing them is enough do i really have to disinfect them as well to protect myself from the sauce cough to virus from. him or you must also take my mask off we're far enough apart disinfecting your hands is the best option we should do it in everyday life as well when you get off a subway or bus because you can't wash your hands there it's good to have a little bottle of disinfectant with you at all times to kill off any viruses.

what else should we do to protect ourselves from the virus you know i did this to use a disinfectant mouthwash because the nose mouth and throat where the virus can multiply and we should nip that in the butt and kill any particles as soon as possible. on the proper anti microbial agent mind you not just any old male friends. i believe but that's fine if you want to smell sweet but it won't kill viruses comment i mean to go into so gardening with the mountains interesting i have another question about masks cloth ones ever be tuesday supposable ones we often wear them all day long on public transport and so on what's the right way to deal with them. after 2 hours a face mask will be sought and viruses on the in a side slowly move to the outer side so after a couple of hours the surgical mask you're wearing with the blue surface is going

to be wet and then it's time to put on a new one life a surgical or medical mask like yours is the mask of choice or someone. who so you recommend this kind of mess but how should i keep it clean. if i touch the surface . is that a mistake from a fire thank you it was good if you know it doesn't matter. just disinfected your hands. or put it on. over one ear and then the other or both at the same time and down over the chin at the top there's a strip of metal. against the nose around the nose and under your glasses until it's nice and snug. when you're breathing normally nothing gets through the mask has 3 layers it's a good mechanical barrier. coming in there must kind of be disinfected and used again. yeah the mother has

a call yes when you get home turn on the oven preheated to 70 degrees celsius and then put the mask in for half an hour or 3 quarters of an hour. then one another. for then the mask is entirely free of any corona virus particles and there's no risk of infection. that's from even disposable masks yeah. yes they're called disposable for a very different reason they were developed for medical use in an operating theatre everything has to be sterile. so before i put supper in the oven i should bake my mask. not. exactly when you come home turn on the oven this is important and it's astonishing that people don't realize this sort take it seriously. though when you have to preheat the oven.

i mean like with ready to bake rolls from the supermarket it always says preheat the oven before you put them in. and many people 1st put their masks in the oven and then turn it on and pull them out after half an hour that's wrong you need exactly 70 degrees for half an hour if the oven warms up part of that time 40. 5060 degrees and so on it's not good enough many thanks that was professor with us on in good shape. do you know what my favorite place in this house is it's the kitchen it's simply the place to be it's we. eat it's when together with my family especially in times of the coronavirus it's very important to be very good on the kitchen so he's your menu for today. maria and camilla they share a hobby cooking. part of a mile also spends

a lot of time in kitchens he's a food safety inspector today they're going to cook together. wash their hands. 30 seconds now our families tell their quote you out you need to wash your hands for 30 seconds and you should take off all of your jewelry. it's also advisable to wash your hands now and then while you're cooking that's the safest way of making sure the food stays jam free. it makes dessert tiramisu the recipe calls for rex the food inspectors alone bells are ringing. off the hens. so i think we know why there's a salmonella risk. and then sit outside on their eggs is eggs can get contaminated with germs and bacteria on their passage through the cloaca so separating eggs is quite dicey. if it. gets the ok comes into contact with the shell.

the egg shouldn't be reduced because the bacteria could end up in the actual egg wash your hands after handling eggs and let's just didn't cut off the 1st one there so you can clean the parts of the letters that are hard to get into this middle. which is very compact sometimes there's a bit of sand and grit in there. give everything to make sure all the debts gone. back to the did that as well as tiramisu has mask a pony and it's this can go off and needs to be kept in the fridge. this is already the question is where do we put it will only be serving it in a few hours and we'll be doing some more cooking in the meantime it needs to be covered with oil and kept in the fridge for the time being the tiramisu is left to chill. things can get chaotic in the kitchen and mistakes are easily made.

paula this is a perfect example let me give you a paper towel you drive your hands on the used. any germs that were on it are all over your hands it's also a good idea to wipe the chopping board with a paper towel to. paper towels need to be thrown away the next challenge she now is trying to histamine toxicity. use all this up today and open tuna fish can in the fridge is not a good idea. in this cling film helps keep it crisp and bacteria free time to prepare the meat meat and poultry can be easily contaminated if i'm not really sure should i rinse it. isn't enough to make sure it's well cooked doesn't that get rid of any bacteria and. really should get

rid of any bacteria this piece of meat is dry so i wouldn't expose it to moisture no. i would just cook it it's worth running produce that you need to defrost under cold water trying it with kitchen roll up so that any bacteria get rinsed off. to get. this meat is fresh and dry so the team can stop preparing it's very important after the turkey has been on it the chopping board has to be cleaned with boiling water but there are different roles for the mince meat as you can read here you can keep it opened at a maximum temperature of 2 degrees for 2 days 2 degrees is no problem in the meat counter at the supermarket but a normal fridge isn't that cold with the cold. how safe is touching me to poultry with all bare hands. for. germany

double in number every 20 minutes. so we. will be fine. we can needed with our hands and. the turkey must be well cooked. the me to. follow camillo and maria looking forward to tucking into that street course many. will have to piss off i didn't feel we were being told off as of young people are clueless and he was nice about that we all learned a lot taking these precautions isn't any extra work. and so long as a few basic rules are followed we don't need to worry and we can all just enjoy eating well. good shape your weekly health show on d.w. covers many aspects of health care. we look at what's new in medical treatment

would you like to change the situation. the problem are there. any works for people a company that wants to improve access to hygiene and toilets. how many of you know about people who are new kind of toilets it will help make things cleaner and healthier it's not just a bag. there are chemicals inside which fight the smell and kill harmful bacteria. that was in 2013 no sewerage no real toilets instead single use plastic bags were meant to solve the sanitation problem in shantytowns. kibera on the outskirts of the kenyan capital nairobi is one of the biggest informal settlements in africa it's estimated that between 300001 1000000 people live here but it's impossible to know exactly

and grew up here. she knows the nicer side of kibera. but also the bad sides garbage collected in the streets the biggest problem is that people don't know what to do with their own bodily waste nobody has a toilet in their home. where nature calls people are forced to use the few open spaces or use plastic bags which they throw away the result is that fecal matter spreads diseases like typhus and cholera. diarrheal diseases one of the leading causes of death here. is typical of many places in the world where people have no access to adequate

sanitation the world health organization says it's a situation that affects some 2000000000 people. thanks to the people who toil at the situation in kid beera is changing because the waste is collect. did instead of being thrown on to the roof. yeah we are coming to you to people you do out something that's a really big task the bag toilets may look like the old flying toilets but they're actually something different. from. the bag contains 5 grams of artificial urea when it comes into contact with feces it produces ammonia gas that kills the pathogens in human excretions. before it was a thing we used to throw the frying toilets on the railings but when the railway

line was cleaned the workers just threw everything back. what did i know sometimes you could barely walk out the door without stepping in it children were often sick and had diarrhea. with the new bags this is improved. night it's also dangerous to go out here time and again women are raped in kibera under looking for a place where they can do their business and the public toilets are far away and close tonight. amanda. is single use toilets to give women more freedom and safety but it's not for free each bag costs $3.00 kenyan shillings about 3 euro cents for a daily family income of one or 2 euros it gets expensive especially in a larger family nevertheless the project has been a success. how does it look today

kibera has developed on the edge of the settlement there are new apartment blocks. there are sealed roads. and the government has build public toilets. here residents can not only use hygenic toilets but they can also shower. facilities still aren't enough for all the people who live here all the same it is a big improvement and the people who bags demand has fallen thanks to these positive developments but they are still used in more than 100 schools in bira. children 2 continents. one giant problem and we are going to see.

how well crime a change of fact us and our children. learn. w dot com slash water. public toilets for most people the dirtiest place they can ever imagine and in times of this global pandemic there's this question should they use public restrooms anyway so this theoretically risk for infection so it's very important to keep an eye on your personal hygiene. damita public toilets a new nick it's not necessarily a job many would want but he says he doesn't mind in fact he's committed to being thorough and doing a good job. it has a positive knock on effect. and

people are relieved to find the toilets clean and they make sure that they stay clean for those who come after them but if the toilets are already dirty they make them even dirtier. it takes time to do a good job i don't usually manages 8 sets of toilets for shifts he visits most of them twice a day because the gap between cleanings shouldn't be more than 6 hours. because of the covert $900.00 pandemic he also makes an extra call each day to apply and disinfectant that would kill corona virus particles. but in general how easy is it to get infected with a pathogen and a public toilet zombie in a mood as a consultant and cleaning and hygiene management working with companies and public sector institutions. and.

she's going to do a hygiene test for us at a public toilet picked at random and cook sovereign on the north sea coast. ultraviolet light reveals all kinds of things other way. invisible to us line blood and urine 1st on the lady's twilight. yeah it looks quite good and there are a few splashes on the tiles i but the toilet itself is very clean. yeah the seat is key that's where hygiene is decisive. here too it's fine i can say this toilet is clean and i can feel good about it. he. says it is not so much a shortage of cleaning stuff that leads to dirty toilets but inappropriate behavior on the part of visitors to public toilets urine else have

a distinct set of hygiene issues. the area around a year and all is always at risk of hosting splashes. a lot depends on the direction of the flow and the accuracy of aim. but the cubicle walls the tiles and the area beneath your and all shouldn't be too badly affected my overall impression here is positive. there are no residues on the dispensers. so i can wash my hands here under hygenic conditions. on the home it's not the toilets and the runnels themselves that are especially dirty but door handles faucets and hand dryers. pits you put them on nowadays 40 percent of users don't wash their hands after going to the toilet there's a rhyme children used to learn that goes after you play and before you eat you
