Tonight we learned deaths linked to ice cream tainted with bacteria were part of an outbreak that had actually been going on for years. In april, Blue Bell Creameries recalled product from 23 states because of listeria which can be fatal to those with weak immune systems. In part 2 of our investigation, jim axelrod shows us how the case of the mystery deaths was solved. Reporter when megan davis and team from the South Carolina department of health randomly sampled ten products from a local Blue Bell Distribution Center in january, the last thing they expected to find was listeria. It was unbelievable, actually. We never in a million years thought we would find a positive sample. Reporter two of the ten samples tested positive. But just to be sure, they went back and collected 30 more. All 30 of the samples that we tested, tested positive for listeria. Reporter stunning. Yeah, stunning. A little scary that those products were going to consumers. Davis uploaded their find noogz pulsenet, a database of dna fingerprints the center for Disease Control monitors to identify outbreaks nationwide. A group that matched. Reporter dr. Robert touks is Deputy Director of the food Borne Disease division. The listeria germs found in South Carolina in the ice cream matched illnesses in a hospital in kansas. Reporter that hospital was via saint Christie Francis in wichita. Listeria sickened five patients over the past year. But the hospital couldnt figure out where it was coming from. The listeria patterns found in South Carolina solved the mystery in kansas. It turns out all five of the patients had been served milk shakes made with Blue Bell Ice Cream. In mid february, blue bell quietly pulled all of the i cream made on the machine that produced the ice cream testing positive in South Carolina citing a quality issue. Via christie had blue bell product in its freezers. The Kansas Department of health tested 45 them and found another hit. When that was loaded up into the pulsenet database, it matched five other patients. But these werent recent. Reporter these five cases came from three different states. Going back to 2010. Unknown and unappreciated to any one a lowlevel outbreak was going on for, four or five years. Reporter an outbreak no one was looking for that very nearly went undetected. Our inspector could have picked two different ice cream products to test. What if he hadnt picked the two samples. It may have had a different outcome. Pulsenet enabled the cdc to trace tainted ice cream not just to blue bells main plant in texas but to a blue bell factory in broken arrow, oklahoma as well. Blue bell said it is increasing focus on sanitation and cleaning and is being evaluated by independent microbiologists. In a statement to cbs news, blue bell said our top priority and commitment is to pre deuce high quality, safety, Delicious Ice Cream for our customers. Fascinating detective story.

For all those men who claim they read playboy for the articles. Youre about to get a chance to prove it. Thats next. ,,,,,,,, finally tonight, is it news when a major publication promises to cover more of what made it famous . It is when the publication is playboy. Heres anthony mason. Reporter from its first issue in 1953, publisher h of the the hugh hefner. I started playboy. He called his magazine a pleasure primer for the masculine taste and a smart swinging lifestyle that hef came to embody. On playboys 50th anniversary in 2003, he said. In a very real way in terms of pop culture and sexual attitudes, we do live in a playboy world now. Reporter the magazine that gave the american male the playmate of the month, the nude centerfold, its signature declared the era of full nudity over. Why, playboy explained in a statement. The short answer is, times change. Dom ni Dominique Patton hugh hefner is an icon and leader in the battle of sixable liberation. Reporter in a way, playboy was overtaken by the revolution it helped unleash. With the internet making pornography easily available, the magazine circulation has dropped. For more than 5. 5 million in 1975, to little more than 800,000 leaders today. The real basis of the change is the bottom line they have got to do something. Theyre losing readers. Reporter when playboy removed nudity from its website last year, traffic soared from 4 million to 16 million unique users a month. The average age fell from 47 to 30. So the magazine will still show women in provocative poses but they will no longer be fully nude. And yes, playboy will still feature what men always said they really bought it for, the articles. Anthony mason, cbs news, new york. And thats the cbs overnight news for this wednesday. For some of you, the news continues. For others, check back with us a little bit later for the morning news and cbs this morning. From the Broadcast Center in new york city, im scott pelley. Welcome to the cbs overnight news. Im michelle miller. The democratic president ial candidates squared off last night in las vegas. For the first of six primetime debates. It was Bernie Sanders first real chance to challenge Hillary Clinton in person. They were joined on stage by former Maryland Governor martin omalley, rhode island governor, and former u. S. Senator james webb. Here is some of what they had to say. Do you want to shield gun come pacup paenz . Of course not. This was a large bill. For example, do i think a gun shop in the state of vermont hat sells legally, a gun, to somebody, that somebody goes out and does something crazy. That the gun shop owner should be held responsible. I dont. On the other hand where you have manufacturers and you have gun shops knowingly giving guns to criminals, or, aiding and abetting that, of course we should take action. Secretary clinton, is Bernie Sanders tough enough on guns . No, not at all. I think we have to look at the fact that we lose 90 people a day from gun violence. This has gone on too long. Its the time the entire country stood up against the nra. The majority of our country supports background checks and even the majority of gun owners do. Senator sanders did vote five times against the brady bill. Since it was passed more than 2 million prohibited purchases have been prevented. He also did vote as he said for this immunity provision. I voted against it. I was in the senate at the same time i wasnt that complicated to me. It was pretty straight forward to me. He was going to give immunity to the only industry in america. Everybody else has to be accountable. But not the gun manufacturers. We need to stand up. And say, enough of that. We are not going to let it continue. Well bring you all in on this. Senator sander, you have to be able to respond. As a senator from a rural state. What i can tell secretary clinton that all the shouting in the world is not going to do what i would hope all of us want. That is keep guns out of the hand of people who should not have those guns. And end this horrible violence that we are seeing. I believe that there is a consensus in the country. A consensus said we need to strengthen and expand instant background checks, do away with the gun show loophole that we have to address the issue of Mental Health the we have to deal with the straw man purchasing issue. And that when we develop that consensus, we can finally, finally do something to address the gun. Governor chaff echtee whats greatest National Security threat to the United States . Nuclear iran the biggest threat, isil, climate change, makes cascading threats even worse. Secretary clinton . I think it has to be continuing threat from the spread of nuclear weapons, Nuclear Materiel that can fall into the wrong hand. I know that terrorists are constantly seeking it. Thats why we have to stay vigilant but also united around the world to prevent that. Senator sanders . The Scientific Community is telling us if we do not address the Global Crisis of climate change. Transfer away from fossil fuel to Sustainable Energy the planets we live and our grandchildren may not bow he habitable. Our relationship with china. Our greatest daytoday threat is cyberwarfare against the country. Greatest military operational threat is resolving situations in the middle east. You served in vietnam. A marine. Once a marine always a marine. A decorated war hero. Became secretary of the navy. During the vietnam war the man next to you, senator sanders, applieds a for status as a c conscientious objector, can he serve as a credible commanderinchief . Everybody makes their decisions. When a time there is conscription. As long as they go through the Legal Process that our country requires, i respect that. And, it would be for the vote tires decide to, whether senator sanders or any one else should be president. I will say this, coming from the position that i, what i have come from, from a military family, with my brother, a marine, my son was a marine in iraq i served as a marine. Five years in the pentagon, i am very comfortable that i am the most qualified standing up here today to be your commanderinchief. When i was a young man, i am not a young man today. When i was a young man, i strongly opposed the war in vietnam. Not the brave men like jim who fought in the war, but the policy which got us involveden that war. That was my view then. I am not a pacifist. Anderson, i supported the war in afghanistan. I supported president clintons effort to deal with ethnic cleansing in kosovo, i support air strikes in syria, what the president is trying to do. Yes, i happen to believe from the bottom of my heart that war should be the last resort that we have got to exercise di policemen see. I am prepared to take this country into war if that is necessary. Sequester Terry Clinton are you going to be testifying before Congress Next week about your emails for eight months you havent been able to put it behind you. Dismissed it. Joked about it. Called it a mistake. What does that say about your ability to handle crisis as president . I have taken responsibility. I said it was a mistake. What i did was allowed by the state department. It wasnt the best choice. I have been as transparent as i know to be. Turning over 55,000 pages of my emails. Asking that they be made public. And you are right. I am going to be testifying. I have been asking to testify for some time. And to do it in public which was not originally agreed to. Isnt it a little hard forup to call this just a partisan issue. There is an fbi investigation. President obama himself two days ago said this is a legitimate issue . I never said it wasnt legitimate. I said i have answered all the questions if i will certainly be doing so again before the committee. But i think it would be really unfair not to look at the entire fix ch picture. This committee spend 4. 5 million of taxpayer money. They said they were trying to figure out what we could do better to protect our diplomats so Something Like benghazi wouldnt happen again. Let me Say Something that may not be great politics. But i think the secretary is right. And that is that the American People are sick and tired of hearing about your damnemails. Thank you. Thank you. Me too. Me too. You know . The middleclass. Anderson. Let me Say Something about the media as well. I go around the country. Talk to a whole lot of people. Middleclass of this country is collapsing. We have 27 Million People living in poch poverty. Massive wealth. Income inequality. Trade policies have cost millions of decent jobs. The American People want to know whether we will have a democracy or an oligarchy as a result of citizens united. Enough of the emails. Lets talk about the real, use facing america. Round two of the democratic president ial debates is saturday november 14th in des moines, november 14th in des moines, iowa. Enough pressure in here for ya . Ugh. My sinuses are killing me. Yeah. Just wait til we hit ten thousand feet. Im gonna take Mucinex Sinusmax. Too late, were about to take off. These dissolve fast. Theyre new liquid gels. And youre coming with me. Wait, what . you realize i have gold status . Do i still get the miles . New Mucinex Sinusmax liquid gels. Dissolves fast to unleash max strength medicine. Start the relief. Ditch the misery. Lets end this. Its the final countdown the final countdown if youre the band europe, you love a final countdown. Its what you do. If you want to save fifteen percent or more on car insurance, you switch to geico. Its what you do.

Ten people got sec from the bacteria. Three died. The Company Recalled 8 million gallons before all of this blue bell was the number three brand in the nation. Sold in 23 states.

And plastered the city with signs. Well, god bless blue bell. A fantastic product. They have done a lot for the community. At the same time a bad side of blue bell. Everything was overlooked. Reporter for the last seven months leading up to the shutdown. Terry schultz operated this machine at the blue bell factory. A lot of time i walked in there. There was ice cream all over the floor. Reporter what do you mean ice cream all over the floor . Some times the machines you would go hay
