Japan, Russia Tsunami: What Is Safe To Eat? Explained As Floodwater May Contaminate Food
Following an 8.8 magnitude earthquake in Russia, tsunami waves also reached Japan's Pacific coastline, prompting alerts throughout the region.
A powerful 8.8-magnitude earthquake struck off Russia's Kamchatka Peninsula on Wednesday, triggering tsunami waves across the Pacific. In Russia, the coastal areas of the Kuril Islands have reported flooding and damage to buildings. Meanwhile, tsunami waves have also reached Japan's Pacific coastline, prompting alerts throughout the region.
Aerial footage from Severo-Kurilsk in Russia shows seawater flooding streets and breaching inland areas. Warnings have also been issued for parts of the US such as California, Alaska and Hawaii, as well as coastal regions stretching towards New Zealand, AP reported.

As rescue and recovery efforts continue, a major concern for affected communities is food safety. When floodwaters enter homes and storage areas, they can bring in sewage, harmful chemicals and bacteria, which can make food unsafe to eat.
Here are the key safety measures people should follow regarding food and water in tsunami-affected areas:
Discard Food That Came In Contact With Floodwater
Any food that has come into contact with floodwater must be thrown away immediately, especially items like raw meat, fish, poultry, eggs and cooked leftovers. Floodwater can carry sewage, chemicals and bacteria, and exposure can make food unsafe to eat.
Food left at room temperature for over two hours should also be discarded as bacteria multiply rapidly in such conditions. If you notice any unusual smell, colour or texture, do not take a chance, consume only what is safe as eating contaminated food can lead to serious foodborne illnesses.
Stick To Sealed, Packaged Food
It is safest to eat only food that was sealed in waterproof packaging before the flooding. This includes commercially packed items like granola bars, dry fruits, nuts and other sealed snacks. Make sure the packaging is intact and has no leaks.
Inspect Cans Carefully Before Using
Canned food can be safe to use, but only if the can is undamaged. Avoid using any cans that are bulging, leaking, rusted or dented. Food containers with screw caps, snap lids, crimped caps or flip tops should be discarded if they have been in contact with floodwater.
Clean, Safe Water Is A Must
Drinking and cooking water must be safe. Use bottled water if available. If not, boil water thoroughly or treat it using water purification tablets as advised by health authorities. Even for washing hands, cooking utensils or brushing teeth, only use water that is safe.
Keep Hands And Surfaces Clean
Always wash your hands with clean water and soap before handling food or eating. If clean water isn't available, alcohol-based hand sanitisers can be used temporarily. Clean all kitchen surfaces, utensils and containers with soap and water if they have come in contact with floodwater. Sanitise with a bleach solution or by boiling when possible.
How To Decide About Thawed Food
If the power supply is affected and freezers are not running, check the condition of thawed food. If food still feels refrigerator-cold or contains ice crystals, it may be safe to refreeze or cook. Otherwise, it is best to discard it if there is any doubt to avoid any future problems.
Infant Feeding Needs Special Care
For babies who are not breastfed, only use pre-mixed formula that comes in ready-to-feed cans or containers. Do not mix formula with tap water or untreated water under any condition. Use bottled water or boiled water as a last resort.
Follow Official Alerts
Always follow instructions from local emergency services and health departments. They will provide updates on food and water safety, evacuation measures and relief resources as the situation develops.

Health Talk: Taking the road to hepatitis elimination
The International Agency for Research on Cancer (IARC) recently classified hepatitis D as carcinogenic—cancer-causing—to humans, just like hepatitis B and C. Hepatitis D, which only affects individuals infected with hepatitis B, is associated with a two- to six-fold higher risk of liver cancer compared to hepatitis B alone, it added. (AP/ Representative photo) Hepatitis D, which only affects individuals infected with hepatitis B, is associated with a two- to six-fold higher risk of liver cancer compared to hepatitis B alone, it added. Viral hepatitis – types A, B, C, D, and E – are major causes of acute liver infection. Among these, only hepatitis B, C, and D can lead to chronic infections that significantly increase the risk of cirrhosis, liver failure, or liver cancer. Each year, July 28 is observed as World Hepatitis Day, as viral hepatitis continues to remain a serious public health threat and one of the primary causes of liver cancer. Yet most people with hepatitis don't know they're infected, says the World Health Organization (WHO). According to the UN health body, types B, C, and D affect at least 300 million people globally and cause at least 1.3 million deaths each year, mainly from liver cirrhosis and cancer. In a paper published on Monday, The Lancet Commission also mentioned that three in five liver cancer cases happen due to preventable risk factors, including fatty liver, alcohol, and viral hepatitis. It also added that obesity-linked cancer cases are on the rise. The majority of liver cancer cases can be prevented by reducing levels of viral hepatitis, alcohol consumption, and MASLD (metabolic dysfunction-associated steatotic liver disease – previously called non-alcoholic fatty liver disease), it said. Liver cancer is already a major cause of death and disability. Globally, it's the sixth most common cancer and the third leading cause of death from cancer. Interestingly, the Commission estimated in the paper that at least 60% of liver cancers are preventable via control of modifiable risk factors, including hepatitis B virus (HBV), hepatitis C virus (HCV), MASLD, and alcohol. While there are preventive measures and treatment available to combat this public health threat, last year's Global Hepatitis Report underscored some challenges that majorly impact disease management. According to the report, testing and treatment coverage remain critically low: only 13% of people with hepatitis B and 36% with hepatitis C had been diagnosed by 2022. Treatment rates were even lower – 3% for hepatitis B and 20% for hepatitis C – well below the 2025 targets of 60% diagnosed and 50% treated. Integration of hepatitis services remained uneven: 80 countries have incorporated hepatitis services into primary health care, 128 into HIV programmes, and just 27 have integrated hepatitis C services into harm reduction centres. The next challenge, according to the report, will be to scale up the implementation of prevention, testing, and treatment coverage. Achieving WHO's 2030 targets could save 2.8 million lives and prevent 9.8 million new infections. With declining donor support, countries must prioritize domestic investment, integrated services, better data, affordable medicines, and ending stigma, said experts in the report. 'Every 30 seconds, someone dies from a hepatitis-related severe liver disease or liver cancer. Yet we have the tools to stop hepatitis,' WHO director-general Tedros Adhanom Ghebreyesus said in a statement on World Hepatitis Day. He is right. We have the tools at our disposal; all we need is for stakeholders—governments, civil society, community leaders, etc.—to come together, to jointly work towards eliminating hepatitis.

Canada is choking as wildfire smoke smothers cities and spreads into US Midwest; Health warnings issued
AP Canada is choking as wildfire smoke from the Prairies triggers extreme air-quality warnings, painting skies orange and pushing pollution to dangerous highs across the country and into the US Thick wildfire smoke drifting east from Canada's Prairie provinces has blanketed large parts of the country, triggering special air-quality warnings and health advisories from British Columbia to Quebec. Environment Canada issued alerts Saturday(August 2) citing 'extremely high' levels of pollution in regions of Saskatchewan, Manitoba, Ontario, and the Northwest Territories, with the Air Quality Health Index (AQHI) hitting level 10 or above, considered 'very high risk' for public health. The smoke, coming from hundreds of wildfires burning in Canada's western interior, has reduced visibility, tainted skies with an orange hue, and raised alarms for vulnerable populations, including children, the elderly, and people with asthma or heart hardest-hit areas include La Ronge, Sask., Flin Flon, Man., and Fort Simpson in the Northwest Territories, where the AQHI remained in the 'extremely high' range for several hours Saturday. Winnipeg was the only major Prairie city under a special air-quality statement, while northern Alberta, including Fort McMurray, is expected to see similar conditions by Sunday, according to Alberta's wildfire smoke forecast model. Environment Canada issues air-quality warnings when AQHI levels exceed 10 for at least six consecutive hours. A special air-quality statement, meanwhile, is triggered when index levels reach between 7 and from Canadian wildfires has also affected US cities. Over the past week, Chicago, Minneapolis, Detroit, and other Midwestern hubs registered dangerous AQI levels, prompting health alerts. In Minnesota, it marked the longest consecutive air-quality advisory in state agency warns of mild symptoms such as eye, nose, and throat irritation, while more serious cases could involve chest pain and severe coughing. Pregnant individuals, infants, seniors, and people with respiratory illness are most at advise people to stay indoors, use HEPA filters or N95 masks, and avoid strenuous outdoor Edmonton, where a separate heat warning remains in effect, officials have activated emergency cooling stations and are distributing water through fire hydrants and peace officers.

One in five Indians to be senior citizens by 2050, NHRC urges culturally rooted policies
New Delhi, Aug 2 (UNI) India is projected to have nearly 35 crore elderly citizens by 2050, with one in every five individuals belonging to the senior age group, posing a significant challenge for policymakers across the country, experts said today here at an event. They emphasised the imperative to develop family and community-based care models that draw strength from India's traditional family values while incorporating global best practices. Viewing ageing as a national asset, NHRC Secretary General, Bharat Lal calls for adapting Scandinavian and Japanese models into India's policy frameworks entwined with its cultural context. In his inaugural address on 'Ageing in India: Emerging realities, evolving responses', NHRC Chairperson, Justice V. Ramasubramanian said India has a rich cultural tradition advocating care and reverence for the elderly as a fundamental societal value. In this context, he also drew references from the Sangam literature and the Yajur Veda. He called for the integration of these ancient values and principles into modern policy frameworks to ensure the dignity, protection and well-being of senior citizens, in alignment with the NHRC's mandate to uphold human rights. In his special address, Dr. Vinod K. Paul, Member (Health, Nutrition and Education), NITI Aayog, emphasised the importance of healthcare and social security frameworks for the ageing population. He said that empowering families to take care of their elderly should remain the foundation of India's approach. On the occasion, a report 'Ageing in India: Challenges and Opportunities' was also released highlighting inclusive and community-led healthcare for elderly people in the country. UNI AJ GNK
