Seed treatment may make sprouts safer

first_img The experiment also showed that to consistently remove the pathogens, it took between 8 and 19 hours of soaking in the sanitizer and that the minimum ratio of mung beans to sanitizer (weight to volume) was 1:4. He said one possible drawback of the sanitizer is that seeds have to be soaked in it longer than what some sprouts producers are used to. “Some people just soak them for 2 or 3 hours. So some people would have to soak the seed a bit longer than they do,” he said. “It appears to be useful within all its limitations,” he said. He said the researchers “really loaded up the seeds” with pathogens, making decontamination a tough challenge. Although SOC is commercially available, it has not been approved for use on seeds in the United States or Canada, according to Warriner. Outbreaks of Salmonella infection linked with sprouts—normally eaten raw—are reported periodically. One outbreak in Ontario last year involved 600 people who had eaten mung bean sprouts. The US Food and Drug Administration (FDA) recommends that seeds used for sprouts be soaked in a 2% calcium hypochlorite (bleach) solution, but that measure is not completely effective, according to the Centers for Disease Control and Prevention. In trying the treatment on other kinds of seeds, the researchers found that it worked well on alfalfa, soybean, flax, and cress seeds, but results with clover, mustard, and radish seeds were mixed. With several other kinds of seeds—chick pea, sunflower, buckwheat, sesame, and onion—the treatment failed to prevent contamination. Batches of contaminated seeds then were soaked for varying intervals in varying concentrations of the sanitizer, and a control batch of mung beans was soaked in the calcium hypochlorite solution for 20 minutes. Afterward the seeds were rinsed with water and allowed to germinate for 4 days. The sprouts then were tested for Salmonella and E coli O157:H7. Jul 13, 2006 (CIDRAP News) – A chemical sanitizer now used in contact lens solutions and toothpaste may help solve the problem of keeping pathogens like Salmonella and Escherichia coli out of edible sprouts, according to a study published in the July issue of the Journal of Food Protection. See also: A team led by Keith Warriner, assistant professor of food microbiology at the University of Guelph in Ontario, decided to find out if an existing sanitizer containing chlorite could be used to safely decontaminate seeds used for sprouts. The chemical is a “stabilized oxychloro (SOC)–based sanitizer” that is sold commercially as Germin-8-or, according to their report. Warriner’s group tested the sanitizer on mung bean, alfalfa, and a number of other kinds of seeds, comparing it with the FDA-recommended calcium hypochlorite treatment. Seeds were soaked in a solution containing five different strains of either Salmonella or E coli O157:H7 for 20 minutes and allowed to dry at room temperature. Why the substance worked on some seeds but not on others is unclear, the report says. But seeds on which the treatment worked germinated faster than the others, suggesting that “protective sites” within the slower-germinating seeds might have protected microbes from the sanitizer, the authors write. They also speculate that natural antimicrobials released by seeds may play a role. While the treatment eliminated the pathogens, tests showed that treated and untreated batches of seed contained about the same overall levels of bacteria, as indicated by aerobic plate counts. The authors say this suggests that the sanitizer did not affect bacteria naturally associated with the seeds (endogenous microflora). Francis Busta, PhD, director of the National Center for Food Protection and Defense and professor emeritus of food microbiology and emeritus head of the Department of Food Science & Nutrition, University of Minnesota, said the sanitizer looks promising as a treatment at least for some kinds of seeds used for sprouts. When several types of seeds heavily contaminated with Salmonella and E coli O157:H7 were soaked in the sanitizer for several hours, sprouts subsequently produced from them were free of the pathogens, according to the report by a team of Canadian and British scientists. The treatment was not toxic to the seeds. The researchers also tested the sprouts for residual sanitizer and found that none of the samples contained more than 1 ppm, according to the article. Warriner said ingesting significant amounts of the substance would be harmful, but trace amounts are not. The investigators found that a solution of 100 parts per million (ppm) was enough to eliminate E coli from mung bean sprouts, while a 200-ppm solution eliminated Salmonella from the sprouts. In contrast, sprouts from seeds treated with the calcium hypochlorite solution remained heavily contaminated with both pathogens. SOC solutions up to 200 ppm did not significantly reduce seed germination or the yield of sprouts, according to the report. “I think it would have to be individually assessed on the kinds of seeds and sprouts,” Busta said. “If I was doing alfalfa sprouts I would strongly consider seeing if I could get this into my protocol. It would also depend on what it costs. A lot of these places [that produce sprouts] are pretty marginal; they don’t have a lot of cash flow.” Kumar M, Hora R., Kostrzynska W, et al.

J Food Protect 2006 Jul; 69(7):1571-78 “We saw this oxychloro compound that was very detrimental to bacteria and kind to plant cells and our cells,” Warriner told CIDRAP News. He said it has been used as a chemotherapy drug as well as in contact lens solutions and toothpastes, “so we knew its properties before we started.” Dec 1, 2005, CIDRAP News story about sprouts-linked outbreak in Ontariohttp://www.cidrap.umn.edu/cidrap/content/fs/food-disease/news/dec0105salmo.htmllast_img read more

French Open bans Hamou over attempts to kiss reporter on live TV

first_imgTennis player Maxime Hamou’s accreditation has been revoked by the organisers of the French Open after he tried to kiss a female reporter repeatedly during a live TV interview.The French player, 21, kissed journalist Maly Thomas while holding her around her neck and shoulders, despite her efforts to duck away.The French Tennis Federation (FTT) condemned the “reprehensible behaviour” and ordered an investigation.Hamou has not commented on his actions.The incident happened after he was knocked out of the first round of the competition on Monday. Several anchors and commentators on the Eurosport programme Avantage Leconte laughed and clapped as it unfolded. The episode drew ire on social media, including from French politician Cécile Duflot.”He kisses her by force, she tries to get away, he holds her by the neck and everyone… laughs #tired,” the Green MP wrote on Twitter (in French).Quoted by the Huffington Post France, Ms Thomas described the player’s actions as “frankly unpleasant”.”If I hadn’t been live on air, I would have punched him.”The BBC has asked Eurosport for comment. It is the latest case to provoke allegations of harassment of female sports reporters. In January 2016, West Indies cricketer Chris Gayle drew a barrage of criticism after he asked a TV reporter for a date in a live interview.He was later fined $7,200 (£4,900) by his club for “inappropriate conduct”. It is not the first time Hamou, who has a career high singles ranking of 211, has caused controversy at this year’s French Open.He walked out of an interview on Friday after a journalist posed a clumsy question. On Monday he also angrily berated an umpire on court, asking: “Why are you here?”last_img read more

Heisler: Lakers already closing in on Anthony Davis, but with lots of competition

first_img AD Quality Auto 360p 720p 1080p Top articles1/5READ MOREUCLA alum Kenny Clark signs four-year contract extension with Packers“Come to the Bucks, man,” Giannis Antetokuonmpo told Davis after their game. “Come to the Bucks.”Davis didn’t comment.Sign up for Home Turf and get exclusive stories every SoCal sports fan must read, sent daily. Subscribe here.Actually, Davis, who played through illness in Milwaukee, declined to talk to the press … perhaps further upset at the latest furor after James told ESPN’s Dave McMenamin that trading for A.D. “would be amazing. Like, duh. That would be incredible.”Unfortunately for A.D., Giannis extended his invitation to join him in a hall, surrounded by press people … making it the first star-to-star pitch witnessed in real time.Of course, nothing can happen unless Davis, who’s under contract through 2019, demands a trade. Now, the latest entry in the campaign to woo Anthony Davis:(Fill in your favorite team’s name here.)What was once mere speculation is now a folk movement as the schedule – aka the Pelican Death March – winds through Boston, where Celtics fans see Davis as their next Bill Russell … to Milwaukee, where the Pelicans took another loss and A.D. got another pitch … to Staples Center, where Lakerdom, starting with LeBron James, sees him as next in their line of Wilt Chamberlain, Kareem Abdul-Jabbar and Shaquille O’Neal.Yes, it’s come to that. The Lakers are now vying for a superstar with Milwaukee, the Great White North of the NBA. If Lakers president Magic Johnson, or anyone in any front office, said what James and Antetokuonmpo did, the NBA would fine them hundreds of thousands of dollars for tampering.Players, on the other hand, are allowed carte blanche to recruit each other.Something similar happened in Boston where The Athletic reported Kyrie Irving and Davis spoke “about what it would be like to play together in Boston, according to a league source.”Not that this may reflect anything more than furious internet competition for “scoops” with “league sources” passing along hearsay, so the A.D.-Kyrie talks might have been anything from serious to fleeting.With A.D. seeming to tilt toward the Lakers after dumping his agent to hire LeBron’s pal, Rich Paul, I’d guess it went like this:Kyrie: “You’ve got to come here. We’d be great together!”A.D.: “Yeah, that would be cool.”This just in! More teams are expected to let Davis know they want him, too: Atlanta, Brooklyn, Charlotte, Chicago, Cleveland, and that’s just through the C’s.Nevertheless, this looks real, rather than a media hype with little basis in fact … like the courtship of James by desperate New York fans from 2008 to 2010, before the Knicks’ declining fortunes knocked them out of the running at the end when it came down to Miami and Cleveland.Wherever the Pelicans go, they’re obliged to rally around Davis with Coach Alvin Gentry proclaiming he’s theirs and will stay that way, and A.D. agreeing … up to a point.“We’re not trading him,” Gentry said before Friday’s loss to the Lakers. “He’s under contract another year and a half. That’s the easy part on our side. That’s from our owner all the way down to the last ball boy on our team. We’re not trading him.”Gentry has been a favorite with the local press from his days as Clippers coach and an assistant on Doc Rivers’ staff.Nevertheless, I’d guess what Alvin is really thinking is: “We’re not trading him. Hopefully, we’ll right the ship, he’ll be moved to stay and this will go away. In the meantime, we’ll keep the faith since that’s all we have left.”Of course, the Pelicans won’t trade Davis until they know they must. A.D. is signaling that his decision point will come this summer, when the team is sure to offer him a “super-max” extension worth approximately $240 million, $87 million more than any other team can.Unfortunately for the Pelicans, it doesn’t look like even that will be enough.“I’d take legacy over money,” Davis told Yahoo’s Chris Haynes last week. “I want to have a legacy. All my people that look up to me, the younger kids, I want them to know about A.D.’s legacy. Championships, the things I do in the community, being a good teammate, playing hard.”Oops. The Pelicans shot from 34-48 to 48-34 last season, but are now 15-18, No. 13 in the West, with A.D. noting he must play “almost perfect” to win.Put it all together and it spells “death spiral.”For the maraschino cherry atop the sundae of the Pelicans’ misery, A.D. went to dinner with James after the loss to the Lakers.LeBron’s comments about trading for Davis burned up the NBA last week with small markets worried their stars might be looted next.Nevertheless, the league put out the word that tampering applies only to management, as much as LeBron pushes the envelope.Of course, the Lakers could tell you how little it can mean to be a mega-market, or even the NBA’s most glamorous franchise, which is what they were when the bottom dropped out after their 2010 title.The Lakers are once more the stars’ destination of choice with the gregarious James, the Pied Piper of NBA players, in the place of Kobe Bryant, an entity unto himself who inspired more respect than affection.The fix is, indeed, in with Davis, as Charles Barkley noted last week, making it official, at least as a conspiracy theory.Not that it was any surprise with LeBron’s history of coordinating his moves with peers, be they stars like Dwyane Wade or role players like Mike Miller.The A.D.-to-Lakers story is now galloping miles ahead of current events. NBA team officials seem reconciled to Davis joining the Lakers, but worry he’ll demand a short-term deal – as LeBron did in Cleveland and Miami – signaling stars’ intentions to exert even more power.In real life, this will take months to play out, presumably in the summer. For the moment, at least, A.D. looks like he’s on track, heading straight into the heart of Lakerdom.center_img Newsroom GuidelinesNews TipsContact UsReport an Errorlast_img read more

A HAPPY TAIL! THE JACKSON FIVE FIND HOMES IN DONEGAL

first_imgThe pups are fit and healthy today after being dumped to die just a month ago.All five pups which were abandoned in a cardboard box in a forest in Ballybofey have now been rehomed.The week-old pups were just hours from certain death when a walker heard their cries.The pups, Labrador crosses, were handed over to the Donegal Pet Rescue group in a suitcase by the man who found them. The group then found a foster bitch in a bid to try and help the pups survive.The pups, dubbed the Jackson Five, all made it and they have been booked by new owners.Ryan McCauley from Donegal Pet Rescue said it is great to think that all dogs have found loving homes despite being left out to die.  A HAPPY TAIL!
