Summary
People may be able to tell that salmon is starting to go bad if it has a strong smell, a slimy coating, or feels mushy rather than firm. Eating bad salmon may lead to health problems, such as food poisoning.
Salmon is a source of protein and omega-3 fatty acids. It can be a great addition to a balanced diet.

There are three main factors a person can use to determine if salmon has gone bad:
Fresh salmon should have a mild, neutral, or fresh smell.
Salmon may have gone bad if it gives off a sour, fishy, or ammonia-like smell.
The appearance of salmon can also indicate whether or not it has gone bad.
Fresh salmon is usually bright in color, in shades of orange or pink. If salmon has gone bad, the color may appear dull, have a gray tinge, or have patches of discoloration.
The texture of fresh salmon is firm, smooth, and slightly moist. If salmon has gone bad, there may be a slimy film on the surface.
A white, filmy substance on raw salmon is another indication that it may have gone bad. However, the white substance that can appear while a person is cooking fresh salmon is different and safe to eat.
If a person has a whole salmon, bulging, faded, or dull eyes may also indicate that it has gone bad.
Fresh, raw salmon should be firm and hold together when handled. If salmon has gone bad, it may have a mushy texture. It may also sink in when pressed or fall apart easily.
Salmon that has gone bad may have a sticky or tacky texture on the surface. Fresh salmon should be smooth and moist in texture.
Symptoms of food poisoning include: diarrhea
abdominal pain
vomiting
headache
fever
Food poisoning from fish, including salmon, can also affect the nervous system. This may cause symptoms such as: tingling or numbness
weakness
blurred vision
headache
paralysis
A person should contact emergency services if they experience any nervous system symptoms of food poisoning or if they experience any other severe symptoms, such as dehydration or bloody diarrhea.
People may want to try the following tips for storing salmon to help prevent it from going bad: Keep fresh raw salmon in the refrigerator (at 40°F or less) for no more than 1 or 2 days before cooking or freezing.
Do not leave salmon out for more than 2 hours.
After cooking, store the salmon in the refrigerator for no more than 3 or 4 days.
Ideally, use frozen raw salmon within 3 to 8 months.

DC rally protests cuts to US veterans programs: ‘Promises made to us have come under attack'
A flurry of red, white and blue American flags fluttered across the National Mall on Friday as more than 5,000 military veterans and their allies descended on Washington to protest against the planned elimination of 80,000 jobs at the Department of Veterans Affairs (VA) and the cancellation of hundreds of contracts for veterans services with community organizations. 'I hope that in the future veterans will be able to get their benefits,' said David Magnus, a navy veteran who decided to travel from Pittsburgh, Pennsylvania, after his doctor told him she was quitting during a recent mental health appointment. Before Donald Trump returned to office in January, 'the VA was good', he said, but since then medical staff have faced harassment that puts the entire system at risk. 'It used to be, you'd call and get an answer,' he said. 'Now, so much is going on that they don't know where to put you.' Organizers said that in addition to the march in Washington, there were more than 200 corresponding actions across the country, from watch parties to vigils held at VA clinics. Many veterans told the Guardian they came to the nation's capital on their own after hearing about the rally online. The VA secretary, Doug Collins, has said the efforts are designed to trim bureaucratic bloat and will have no impact on veterans' healthcare or benefits. Reporting by the Guardian last month found the agency, which provides healthcare to more than 9 million veterans, has already been plunged into crisis. Across the nation, appointments have been cancelled, hospital units closed, the physical safety of patients put at risk. Demonstrators said the Trump administration is seeking to destroy the VA, the largest integrated healthcare system in the United States, with 170 government-run hospitals and more than 1,000 clinics, and replace it with a private voucher program that will provide substandard care. 'We're a generation of service. We volunteered and stepped up to lead. Now we are seeing the promises made to us come under attack,' said Kyleanne Hunter, the chief executive of Iraq and Afghanistan Veterans of America and a Marine Corps veteran who flew multiple combat missions as an AH1-W Super Cobra attack pilot. The administration's proposed budget for the VA, released on Friday, slashes spending for 'medical services' by $12bn – or nearly 20% – an amount offset by a corresponding 50% boost in funding for veterans seeking healthcare in the private sector. 'We're already being starved,' said Sharda Fornnarino, a Navy veteran and one of about three dozen nurses brought to the rally by the National Nurses United union. Fornnarino, who works at the VA in Denver, Colorado, said that while politicians in Washington debate permanent staff reductions, essential healthcare positions are being left vacant. With fewer staff on the floor, veterans on hospice 'are being left to die in their own piss and shit', said Teshara Felder, a Navy veteran and nurse at the agency's hospital in Atlanta, Georgia, said. A blue-ribbon commission established by the agency last year found veterans received significantly better care at lower cost from the public system. Private providers operated with little oversight, they wrote, and 'are not required to demonstrate competency in diagnosing and treating the complex care needs of veterans nor in understanding military culture, which is often critical to providing quality care for veterans'. The VA says the budget submission 'prioritizes care for our most vulnerable veterans, including those experiencing homelessness or at risk of suicide' and 'eliminates nonessential programming and bureaucratic overhead that does not directly serve the veteran'. The march was held on the 81st anniversary of D-day, when Allied troops stormed the beaches of Normandy, a decisive turn in the war against Nazi Germany during the second world war. Organizers said their inspiration goes back even further – to the 'Bonus Army' march on Washington in 1932 during the depths of the Great Depression, when thousands of first world war veterans gathered on the National Mall to demand promised benefits, only to have the US military deployed against them. Christopher Purdy, an Afghanistan war veteran and organizer of today's march, said the Bonus Army rally helped set the stage for the New Deal social programs and eventually the GI Bill, which provided higher education, healthcare and home ownership to veterans returning from the second world war. Other speakers criticized Trump's decision to impose a travel ban on visitors from 12 countries, including Afghanistan, where many of the demonstrators served alongside translators who risked their lives for the US. Shortly after taking office in January, Trump ordered a pause on the US refugee admissions program, putting translators' safety in doubt. 'We all left behind people who are now marked,' said Nadim Yousify, who immigrated to the United States in 2015 after working as a US government translator in Afghanistan and later joined the Marine Corps.

‘She always said, 'I'm going to be famous, dad'': Teen dies after viral TikTok ‘dusting' challenge
The parents of a 19-year-old who dreamed of fame and died after trying the TikTok 'dusting' trend are warning others about its deadly risks. Renna O'Rourke and her boyfriend DoorDashed aerosol keyboard cleaner to her parents' Tempe, Arizona, home without her mother's knowledge, Dana O'Rourke told 12 News. The dusting trend, also known as chroming or huffing, involves inhaling common household cleaners to get high for views online. The sensation causes brief euphoria but can cause instant, fatal damage, often due to heart failure, according to the Cleveland Clinic. After inhaling the keyboard cleaner, Renna went into cardiac arrest, spent a week unconscious in the intensive care unit, and then was declared brain-dead. Renna's parents described their late daughter as 'vivacious and caring and loyal.' Her father, Aaron O'Rourke, told 12 News that Renna loved to sing and lit up every room with her smile and laughter. 'She always said, 'I'm going to be famous, dad. Just you watch. I'm going to be famous,' and unfortunately, this is not under the most optimal of circumstances,' Aaron O'Rourke, told the outlet.. Despite the less-than-ideal circumstances, the O'Rourke family is now working to honor Renna by spreading the word about the dangers of huffing for teens and parents. 'There's no ID required. It's odorless. It's everything kids look for. They can afford it, they can get it, and it doesn't show in mom and dad's drug test,' Dana O'Rourke told AZ Family about access to the trendy chemicals. She added, 'Don't take your kid's word for it. Dig deep. Search their rooms. Don't trust — and that sounds horrible, but it could save their life.' GoFundMe started to help the O'Rourke family with hospital bills, burial and therapy costs, and to spread awareness about huffing has surpassed its $5,000 goal and sits at over $9,000 at the time of publication.
