Low-dose CT chest scans could help detect pneumonia in at-risk patients while exposing them to only small amounts of radiation, a new study has found. The research, published in Radiology: Cardiothoracic Imaging, shows that ultra-low-dose scans can effectively detect pneumonia in patients with compromised immune systems, enabling doctors to treat the infection before it becomes life-threatening. According to the researchers, these scans expose patients to just 2% of the radiation dose used in a standard CT scan.

"This study paves the way for safer, AI-driven imaging that reduces radiation exposure while preserving diagnostic accuracy,” lead researcher Dr Maximiliano Klug, a radiologist with the Sheba Medical Center in Ramat Gan, Israel, said in a news release. He added that CT scans are the gold standard for detecting pneumonia but there are concerns regarding the risk posed by repeated exposure to radiation. There is a solution- ultra-low-dose CT scan. However, the problem is that these scans can be grainy and hard to read, researchers said.

Study Gives Solution To This

To overcome that, Klug's team developed an AI program that could help "de-noise" low-dose scans, making them sharper and easier to read. Between September 2020 and December 2022, 54 patients with compromised immune systems who had fevers underwent a pair of chest CT scans -- a normal dose scan and an ultra-low-dose scan. The AI program cleaned up the low-dose scan, and then both sets of images were given to a pair of radiologists for assessment. Radiologists had 100% accuracy in detecting pneumonia and other lung problems with the AI-cleaned low-dose scans, but 91% to 98% accuracy in examining the scans that hadn’t been improved through AI, results show.

"This pilot study identified infection with a fraction of the radiation dose," Klug said. "This approach could drive larger studies and ultimately reshape clinical guidelines, making denoised ultra-low dose CT the new standard for young immunocompromised patients.

How Can You Detect Pneumonia?

Pneumonia is a lung infection that causes the air sacs in the lungs to fill with fluid or pus and can be caused by bacteria, viruses, or fungi. The symptoms can range from milk to severe, which includes:

Coughing with or without cough

Fever

Chills

Trouble breathing

Chest pain, especially when breathing deeply or coughing

Sweating or chills

Rapid heart rate

Loss of appetite

Bluish skin, lips, and nails

Confusion.

How to detect Pneumonia in coughing newborns and toddlers?

Pneumonia can severely affect newborns and young children as their lungs are comparatively more sensitive. As per Dr Goyal, young children can cough for various reasons including seasonal infections and tonsillitis, which is very common in this age group. But if they look visibly irritable and have poor sleep patterns, then parents must reach out to an expert. "I am not saying that parents must visit a hospital but any local paediatrician would be able to detect pneumonia in your kid.

India’s food safety regulators have stepped up scrutiny on multiple fronts this week. The Food Safety and Standards Authority of India (FSSAI) has tightening packaging rules for pan masala and Maharashtra’s Food and Drug Administration (FDA) taking action against retail outlets over alleged hygiene violations.

From what goes into packaged products to how food is stored and handled before it reaches consumers, these developments come at a time when food safety in India is under tight scrutiny.

FSSAI Bans Plastic And Aluminium Foil In Pan Masala Packaging

Under the new Food Safety and Standards (Packaging) Amendment Regulations, 2026, notified on August 10, pan masala packaging can no longer use plastic-based materials, plastic laminates, aluminium foil or metallised layers.

Pan masala can now be packaged in materials made of paper, paperboard, cellulose and other naturally derived materials, provided they are completely free from plastic and synthetic polymers. Tin and glass containers are also allowed.

The decision follows an earlier draft notification issued by FSSAI in April, which proposed adding specific packaging materials for pan masala to the food packaging regulations.

Why FSSAI Is Targeting Pan Masala's Packaging?

Pan masala sachets have traditionally relied heavily on plastic and foil materials as they are lightweight, inexpensive and the contents are shielded from moisture.

However, such multilayer plastic packaging is difficult to recycle and contributes to persistent plastic waste. The new rules push manufacturers towards packaging made of paper and other naturally derived materials that won't harm the environment.

This does not mean that pan masala itself safer to consume. Pan masala, particularly those containing tobacco or areca nut, continues to be harmful. The regulation is primarily about packaging standards and waste.

Maharashtra FDA Cracks Down On Retail Food Safety

On the other hand, Maharashtra FDA suspended the food license of a Blinkit facility in Malad West after it reportedly found cockroach infestation, improper storage and other hygiene violations that posed health safety dangers.

Officials also flagged expired and damaged products, inadequate pest control, poor waste management and improper food storage practices. The license was suspended under Section 32(3) of the Food Safety and Standards Act, 2006.

The incident highlights why storage conditions matter even when food has already passed manufacturing and packaging checks.

Reliance Retail Outlet Under Investigation Over Kaju Katli Complaint

In a separate case in Buldhana, Maharashtra FDA flagged a Reliance Retail outlet after a consumer complaint alleging fungal growth and live larvae in packaged kaju katli.

Officials inspected the outlet on August 8 and seized 54 kaju katli boxes reportedly. The specific batch mentioned in the complaint was no longer available, while another batch of the same product was found in stock.

These incidents underscore an important point: food safety does not end when a product leaves the factory. Packaging, transportation, storage, pest control, temperature management, expiry checks and hygiene at retail outlets all form part of the food-safety chain.

For consumers, checking the product's packaging, expiry dates, storage instructions and signs of contamination remains important. If a packaged food looks, smells or tastes abnormal, it is safer not to consume it and to report it to the food-safety authority.

England is on the verge of becoming one of the first countries in the world to eliminate hepatitis C, after more than 100,000 people received the life-saving pioneering antiviral drugs through the NHS that was rolled out in 2015.

NHS England said the country has already surpassed the World Health Organization’s target of treating at least 80% of patients diagnosed with hepatitis C. The latest numbers show that 81.5% of people diagnosed with chronic hepatitis C between 2015 and 2024 had started treatment.

Professor Frankie Swords, NHS national medical director, said hepatitis C can cause serious complications including liver failure and cancer. She also said that many people may live with the infection for years without knowing they have it.

“That’s why the NHS has worked hard alongside public health teams and charities to find and treat hidden cases,” she said, adding that England is now “leading the world” on the path to eliminate the disease.

“We are making significant progress towards eliminating Hepatitis C as a public health threat,” said Dr Sema Mandal, Deputy Director – Blood Safety, Hepatitis, STIs and HIV Division at UK Health Security Agency (UKHSA).

She added, "The sharp fall in cases since 2015 shows the impact of expanded testing and sustained access to modern curative treatments, and the commitment of health services and community partners across England."

“Treating over 100,000 people in just 10 years is a remarkable achievement and brings England closer than ever to becoming one of the first countries in the world to eliminate this disease as a public health threat,” Mandal said.

Hepatitis C is a blood-borne virus that primarily affects the liver. If the infection becomes chronic and remains untreated, it may lead to cirrhosis, liver failure and liver cancer. But hepatitis C differs from many other chronic viral infections as it can be cured.

Since 2015, England has significantly expanded access to direct-acting antiviral medicines. These tablets are generally taken for just 8 to 12 weeks and can clear the virus in more than 90% of the patients.

An estimated 50,200 adults were living with chronic hepatitis C in England in 2024, down 61.1% from an estimated 129,000 in 2015.

Deaths linked to hepatitis C have also fallen, with NHS England reporting a 36% reduction over the past decade.

Testing Still Remains Crucial

The biggest challenge for the health officials right now is finding people who do not know they are infected with hepatitis C.

The UKHSA estimates that 84.6% of people living with chronic hepatitis C had been diagnosed between 2015 and 2024. While the number is is encouraging, it still below the WHO target of 90%.

Past or current injecting drug use remains the most important risk factor in England. People who received blood transfusions or blood products before widespread hepatitis C screening was introduced are also considered at risk.

Elimination does not mean that hepatitis C will disappear completely. Under WHO criteria, it means reducing transmission, illness and deaths to very low levels while maintaining strong testing, treatment and prevention systems in public health.

The progress is especially significant because the world is currently far away from WHO’s 2030 viral hepatitis elimination targets. WHO estimates that about 47 million people were living with hepatitis C globally in 2024, while around 240,000 people died from hepatitis C-related causes.

Even as the US faces major outbreaks of Cyclospora and Salmonella infections, the Food and Drug Administration (FDA) has finalized safety guidance for operations handling ready-to-eat (RTE) fresh-cut produce.

The guidance incorporates public comments received on the October 2018 draft and replaces the FDA’s 2008 guidance on fresh-cut produce.

“This guidance represents the agency’s current thinking on the issues related to preventing contamination in fresh-cut produce,” the FDA said.

The agency also encouraged the industry to continue advancing food safety practices, including through best-practice documents tailored to specific commodities and processes.

The FDA’s guidance targets manufacturers and processors of fresh-cut produce and recommends measures such as sanitation controls, supplier verification and refrigeration amid ongoing outbreaks of cyclosporiasis and salmonella linked to fresh produce.

What Does the FDA Guidance Include?

The FDA recommendations are not legally binding and are aimed at manufacturers and processors of products such as chopped lettuce, sliced cantaloupe, diced onions, shredded carrots, coleslaw mixes and fruit salads.

Fresh-cut produce can include a single commodity, such as cut lettuce, sliced cantaloupe, diced celery, diced onions and shredded carrots, or combinations of two or more produce items, such as coleslaw mixes and fruit salads.

The FDA has focused on contamination with pathogens including salmonella, cyclospora, E. coli and listeria.

Fresh-cut produce processors should assess whether these pathogens pose potential hazards that require preventive measures, including supply-chain controls, the FDA said.

The recommended measures include:

• Using safe water
• Washing fruits and vegetables with antimicrobial solutions
• Training personnel
• Improving facility design
• Implementing sanitation controls
• Verifying suppliers
• Maintaining appropriate refrigeration

Why Is Fresh-Cut Produce at Risk?

Fresh-cut produce can be particularly susceptible to contamination because pathogens may be introduced at multiple points, including during growing, transportation, manufacturing, commingling with other products or at retail.

The opportunity for contamination can increase at each stage before the food reaches consumers.

Fresh-cut produce also does not undergo a kill step to eliminate pathogens that may be introduced during these processes, and most products are sold ready to eat.

The guidance provides recommendations and examples of how Preventive Controls for Human Food can be implemented to protect fresh-cut RTE produce from biological hazards.

Cyclospora and Salmonella Outbreaks

The guidance comes as the US investigates outbreaks linked to contaminated lettuce and jalapenos that have sickened thousands of people.

The cyclospora outbreak linked to iceberg lettuce from Taylor Farms has spread to 15 states, with Michigan hit the hardest.

“Americans should feel confident in eating fresh produce, including leafy greens at this point,” Diamantas said during an appearance on CNBC. The FDA said it remains confident that iceberg lettuce linked to the cyclospora outbreak had been effectively removed from the market following the July 17 recall.

The US Department of Health and Human Services also said Tuesday on X: “Cyclospora: contained, American food: safe.”

However, the FDA and CDC say the investigation into the cyclospora outbreak remains ongoing.

Separately, Taylor Farms said Monday that it was recalling prepared foods containing jalapenos from retailers in several states because of potential salmonella contamination.
