together. and now we bring you the latest on another food safety story, about cantaloupe, contaminated with deadly listeria. we first reported on the major recall last night. and as of tonight, at least 22 people have now been infected with listeria. two have died. as many as 4.5 million cantaloupes may be tainted. and abc's jim avila has more now on what listeria is and how it can kill. >> reporter: the listeria outbreak has been traced to one of this country's highest quality cantaloupe farms in a place famous for its melons, rocky ford, colorado, at the fourth generation jensen farms where the remaining crop has been destroyed. >> we're deeply saddened that there's a possibility our family's cantaloupe could have gotten somebody sick. and it's very -- it's -- >> reporter: right now, those 22 americans are in seven states from colorado to west virginia. and cdc investigators expect the number to rise since the jensen farm cantaloupe has been sold in 17 states. >> it's just been pure hell, devastating, unreal. >> reporter: tammie palmer's husband, paralyzed in a colorado hospital after eating cantaloupe nearly a month ago. >> i went over and started patting his face. and i'm like, "chuck, what's wrong?" he couldn't talk or anything, so that's when i call 911. >> reporter: how can this happen in a fruit like cantaloupe, considered safe because of it's thick rind? >> i'm shocked to hear there's listeria bacteria on cantaloupe. >> reporter: the chain of vulnerability begins in the field, with waste contaminated soil or water. it could also come from workers or tools during harvest, or on packaging equipment, refrigerators used during storage. germs on the rind spreading to the flesh by your kitchen knife. >> the most vulnerable point is when it's been cut. >> reporter: the problem is, cantaloupes are not easy to wash. the nooks and crannies can hind the germs. melons should be scrubbed before cut and eaten right away. listeria can grow in the refrigerator, and nearly 25% of all cases lead to death. jim avila, abc news, new york. and moving on today, it is now official. the two political parties have lined up, giving different answers to the question, how to create jobs in america. as you know, president obama has asked for a jobs bill that will give billions in stimulus to local governments and the unemployed. today, house speaker john boehner unveiled his strategy, which focuses on fewer regulations and lower taxes for businesses. but there are a lot of people who cannot wait for this debate. they need jobs now. and "nightline" anchor bill weir sat down with one of the powerhouses behind facebook for some new ideas. >> reporter: three-quarters of a billion people are now on facebook, which has given rise to hundreds of thousands of jobs that didn't exist a decade ago. social media marketing gurus, app developers and, of course, engineers at facebook. >> it's why more students should study computer science. it's a great way to make sure you can be employed for the rest of your life. >> reporter: mama let your babies grow up -- >> that's right. >> reporter: -- to be coders. >> computer scientists, that's exactly right. >> reporter: but even if your skills are more old-fashioned, the most powerful woman in tech says facebook could help you find your next job, thanks to how much information people and companies freely share. for example, any time a young woman in the twin cities changes her relationship status from single to engaged, she get as small ad from a wedding photographer named chris myers. >> i've booked probably 40, 45 weddings from facebook. >> reporter: these ads are cheaper than traditional options and much more tightly targeted. so for as little as 5 bucks a day, a laidoff carpenter in port land could market himself to neighbors who mentioned "home remodeling" on their facebook page. but a savvy job hunter doesn't have to spend anything to research and reach out to the 3 million businesses that use the site. like the solar panel technician who skipped the want-ads and went right to the facebook pages of potential employers. he built a rapport with the companies and understood their cultures in a whole new way. >> and then when he got a job, he said it was like i got to interview the company before i got to meet them. >> reporter: and finally, sandberg says, don't be shy about asking friends to share your resume with their friends and so on. this way, someone with only a few dozen contacts can amplify their reach into tens of thousands of connections. >> jobs for all different kinds of people in all parts of the economy. >> reporter: experts say that 60% of job seekers find a position through someone they know. and these days most of "who you know," well, they're probably on facebook. bill weir, abc news in palo alto, california. >> and you can see more of bill's conversation with cheryl sandberg tonight on "nightline." and a dramatic scene today. an intense fire racing through a cruise ship sailing in the waters off the west coast of norway. two crew members were killed, nine others were hurt and more than 200 passengers scrambled to evacuate in lifeboats. police say some sort of explosion on board started the fire but they're confident that whatever caused the blast, it was accidental. at the white house today, a moving ceremony as president obama awarded america's highest military honor to a 23-year-old marine. sergeant dakota meyer, the first living marine to receive the medal of honor for action in afghanistan. two years ago, caught in a fierce fire fight, sergeant meyer put his life on the line to save 36 others. abc's bob woodruff has the story. >> reporter: in september 2009, sargeant dakota meyer was heading through the extremely dangerous ganjgal valley in northeast afghanistan, traveling with afghan soldiers who were trying to convince villages elders to break away from the taliban. but meyer was ordered to stay back with the vehicles. the rest of his unit went in. insurgents opened fire. you were extremely frustrated. you could not go in. >> oh, i was. >> reporter: feeling helpless, sergeant meyer and staff sergeant juan rodriguez-chavez defied orders and drove their humvee up the narrow track toward the village. >> i never thought i was going to come out. >> reporter: but you went in anyway. >> that's what marines do. >> reporter: for six hours, he made multiple trips into the valley under constant gunfire, rescuing more than 30, but it was too late for his closet friends. >> i just sat down between gunny kenefick and lieutenant johnson and just sat there and shook my head. >> reporter: you took their pulse? >> i did, i did. i knew they were dead, but you just want to wish there is something -- something still going that you can hopefully try at least save one of them. >> reporter: you're wearing bracelets here. >> i am. >> reporter: named for both of them. >> for all four of them. >> reporter: and you're going to wear those bracelets for the rest of you life? >> forever. >> reporter: the guilt is overwhelming. >> i feel like i failed them, i failed their families. i play it over and over. >> reporter: you do? >> every single day. >> reporter: in dreams and when you are awake? >> definitely. >> reporter: and so is the anger about the lack of artillery and air support for the mission which came too late. sergeant meyer received the medal of honor, but insists it is not only for him. >> i won the award for the mari marines, but it's not for me. >> reporter: maybe not, but the president and the country recognized meyer with the highest military award for his actions above and beyond the call of duty. bob woodruff, abc news, washington. >> and by the way, on the eve of the ceremony at sergeant meyer's request, he and the president shared a quiet meeting and a beer. and by the way, five years ago when meyer was in high school, a recruiter told him there was no way he could make it as a marine. let that be a lesson. and still ahead on "world news," pat robertson says it's okay to divorce a spouse suffering from
