What to know about food poisoning illnesses caused by listeria
A listeria outbreak linked to ready-to-eat sandwiches and snacks has sickened at least 10 people in the U.S., and a producer is voluntarily recalling dozens of products sold to retail stores, hospitals, hotels, airports and airlines, federal officials said.
The products were made by Fresh & Ready Foods LLC and were sold in Arizona, California, Nevada and Washington.
Those who fell ill and were hospitalized were in California and Nevada. The outbreak has been simmering for many months: The Centers for Disease Control and Prevention said cases date to December 2023.
Listeria poisoning is caused by a particularly resilient type of bacteria that can survive and grow even during refrigeration. About 1,600 people are infected with it — and 260 die — each year in the U.S., according to the CDC.
Here's what you need to know:
What was recalled?
The voluntary recall covers more than 80 specific products distributed between April 18 and April 25. The products have 'Use By' dates from April 22 to May 19.
Brand names include: Fresh & Ready Foods, City Point Market Fresh Food to Go and Fresh Take Crave Away.
Federal officials say anyone with the products should throw them away or return them. They also suggest cleaning any surfaces that touched the recalled foods.
Where does listeria come from?
Listeria bacteria thrive in moist environments, including soil and water and decaying vegetation and are carried by some animals.
The hardy germs are typically spread when food is harvested, processed, transported or stored in places that are contaminated with the bacteria.
When the bacteria get into a food processing plant, they can be tough to eradicate.
What are the symptoms of listeria?
Foods contaminated with the bacteria can make people sick. Symptoms can be mild and include fever, muscle aches, nausea, vomiting and diarrhea. More serious illness can include headache, stiff neck, confusion, loss of balance and convulsions.
Listeria poisoning is tricky because symptoms can start quickly, within a few hours or days after eating contaminated food. But they also can take weeks or up to three months to show up.
Those most vulnerable to getting sick include the very young, people older than 65 and those with weakened immune systems or who are pregnant.

Does cooking kill listeria?
Listeria can survive and grow in refrigerated food. It can be killed by heating foods to 'steaming hot,' or 165 degrees Fahrenheit (74 degrees Celsius), the CDC says. But that's not always possible — or palatable — for foods that are made to be eaten cold.
Because listeria can survive under refrigeration, it's important to clean and sanitize any surfaces, including refrigerator drawers and shelves, that may have come in contact with the products.

Province holds formal event marking arrival of Gazan families
Premier Wab Kinew says Manitoba is taking early steps toward welcoming a third family from Gaza, as the province marked the arrival of two Gazan families earlier this year with a formal event hosted by the Manitoba Islamic Association. 'Right at the start of the process, but we've started the process of working with the medical experts who are volunteering their time here in Manitoba,' Kinew said. 'Now that we've done it a few times, there is effectively a pathway open.' The first family — a mother and her 11-year-old son — arrived in Winnipeg in January. The second, including a young boy, his two younger siblings, their mother, and grandmother, arrived in May. Since their arrival, both boys have undergone medical procedures and attended multiple appointments. Kinew said the arrivals came after a detailed process involving consultations to identify families in displaced from Gaza with medical needs that could be met by Manitoba's health-care system. He also noted there were 'serious' security screenings and paperwork to navigate international travel requirements. Ruheen Aziz, vice-chair of the Manitoba Islamic Association, said the goal is to continue expanding support to more families. 'These kids need a lot of treatment, a lot of medical care, along with the family,' Aziz said. 'They are medical concerns. They were identified with Doctors Without Borders in Eqypt. We know that the care they require is extensive. That's all I can share on that front. They are adjusting well to the Winnipeg community, the school system, the larger community as well. They're happy to be here.' The children range in age from nine to 12. Both families still have relatives — including husbands and children — left behind in Gaza and Egypt. Kinew acknowledged that the security situation has limited who can be brought over. 'Beyond that, it's not a provincial issue,' he said. 'There really is a limit to what a province can do.'

The families have received an outpouring of donations, including clothes, food, and gifts. Community members have also helped with transportation and translation. During the event, MIA chair Hakim Ghulam and Sheikh Ismael Mukhtar welcomed the families and urged political leaders to take a principled approach to the conflict in the Middle East. 'Do not be pro-Palestinian, do not be pro-Israel, don't be pro-Jews, do not be pro-Muslims,' he said. 'Stand for justice, stand for peace, stand for fairness. Perhaps this is a small step, and perhaps we can do more.' Added Ghulam: 'We need to stand up at this time and become the voice of the voiceless people. And we need to stand up and help to alleviate the suffering that is going on.' Scott BilleckReporter Scott Billeck is a general assignment reporter for the Free Press.

Why exercise helps you sleep and why sleep is good for your fitness routine
Nearly 40 per cent of adults reported getting less sleep than the required amount between 2013 and 2022, according to the U.S. Centers for Disease Control and Prevention. (Pexels/Victor Freitas) The health benefits of a good night's sleep have long been touted by researchers and medical professionals. While you're catching z's, your body is hard at work maintaining your physical and mental health. It does so by repairing and boosting your cardiovascular and immune systems, plus regulating your metabolism. Your brain also consolidates memories and processes information from the day. Yet while experts recommend getting at least seven hours of sleep per night, nearly 40 per cent of adults reported getting less than this required amount between 2013 and 2022, according to the US Centers for Disease Control and Prevention. That's alarming, since sleep deficiency can lead to injuries, physical and mental health problems, less productivity, and an even greater chance of dying, according to the National Institutes of Health. But if you're part of that 40 per cent, there's hope. A raft of evidence shows regular exercise helps you sleep better, and quality sleep makes it easier and more enjoyable to work out. 'The majority of people report that when they exercise, they sleep better,' said Dr. Eric Olson, president of the American Academy of Sleep Medicine and a professor at the Mayo Clinic Alix School of Medicine in Rochester, Minn. 'That can mean they fall asleep more easily, enjoy deeper sleep or sleep in bed more efficiently, which means actually sleeping rather than lying awake.' Exercising enhances sleep for a variety of reasons, according to a 2023 systematic review published in the Cureus Journal of Medical Science. Physical activity increases melatonin production, a hormone that regulates your sleep-wake cycles. It reduces stress, which often keeps people tossing and turning at night, plus boosts your mood. Finally, it helps regulate your body temperature, which is key to sleeping well. The review concluded that regular exercise not only improves your sleep quality, but it may even help manage various sleep disorders, such as insomnia. Exercise can definitely help combat insomnia, Olson said, along with sleep apnea. People with sleep apnea experience repeated shallow breathing during sleep, and may even stop breathing at times (If you think you might have sleep apnea, head to your medical provider right away. It can be dangerous). 'Apnea is often predicated on one's weight,' Olson explained. 'So if exercising helps with weight management, it may also reduce sleep apnea and snoring. Exercising may also help combat restless legs syndrome, another sleep disorder, where you have a compelling urge to move your legs — although some find exercise exacerbates it.' Cooling down before bed is key One key to using exercise to help improve the quality of your sleep is making sure your body temperature has cooled down before heading to bed. This is because a drop in core body temperature signals to your brain that it's time to sleep. Exercising in the morning or afternoon is ideal, then, as your body has the bulk of the day to cool down. But if evening workouts are a better fit for your schedule, it's fine to exercise then. You just need to give yourself 60 to 90 minutes post-workout for your body temperature to lower before going to bed, said Dr. Sara E. Benjamin, medical director of the Johns Hopkins Center for Sleep and Wellness in Columbia, Md. If you don't have that much time to spare for an evening cooldown, skip that vigorous run and try a gentle workout instead, such as tai chi or yoga. 'Yoga before bed can be relaxing, and sometimes it's good to move around before bed so you're not as stiff and are more comfortable sleeping,' Benjamin said. When your sleep improves, your workouts should, too Once your sleep improves thanks to regular physical activity, you may notice your workouts feel easier and are more enjoyable. 'When you don't get enough quality sleep or a sufficient duration of sleep, your stamina and strength will be reduced, which can impair your workouts,' Olson said. 'Also, when you're overly tired because the quality and duration of your sleep aren't adequate, it will be harder to get motivated to work out.' To further the symbiotic relationship between exercise and sleep, consider exercising outdoors rather than at the gym. 'Being outside and having natural light exposure is helpful,' Benjamin said. That's because exposure to natural light is imperative to the operation of your body's circadian rhythm, or internal clock. Your circadian rhythm is a 24-hour cycle that regulates a variety of physiological processes in your body. It's primarily influenced by light and darkness, which cue your body that it's time to wake up or prepare for bed. Yet the link between good sleep and exercising at times is a personal one. Some people will be able to fall asleep even if they exercise right before bed or ingest caffeine, for example. And younger people may find exercise more beneficial to quality sleep than older adults, who tend to have sleep issues. Still, some form of exercise should help most people improve their sleep. And a good night's sleep should make your workouts — and pretty much everything else in your life — more enjoyable.

Young and Barnes: A new city bylaw would help prevent heat-related deaths
Article content In the context of rapidly worsening climate change, cities such as Ottawa are on the front lines of the race to protect residents from the threat of summer heatwaves. According to the City of Ottawa's draft Climate Resiliency Strategy, more than one in three residents lack the means to stay cool as temperatures climb during the summer months. They face increased health-related risks. Article content Article content Just as landlords are required by law to ensure indoor temperatures stay above a minimum in the winter, Ottawa — and other Ontario cities — need to urgently pass bylaws setting a maximum indoor temperature. Article content Article content Statistics Canada estimates that around 36 per cent — nearly 150,000 — of Ottawa households are renters. Many have no power to control the temperature in their units. While Ottawa-specific data is scarce, a national survey from ACORN Canada found that 44 per cent of respondents had no access to air conditioning. When other factors are considered, such as old and inefficient building stock, poverty and the rising cost of living, it is no surprise that cooling is out of reach for too many. Article content Heat risks are worsening Article content Let's be clear: When it comes to extreme heat, the risks are here and worsening. The federal government states that 'extreme heat is the leading cause of illness and death from weather-related hazards in Canada.' A recent federal study shows higher-than-average risk of death during stretches of extreme heat in Canada's largest cities over the past 20 years. Risks were particularly high for people aged 65 or older. Article content Article content Extreme heat doesn't just kill; it worsens heart conditions, triggers mental-health crises and heightens the risk of accidents. This reduces quality of life, diminishes economic productivity and adds to the burden on overstretched health systems. Article content Article content We would never accept an apartment without heat in winter. So why do we tolerate deadly indoor heat in the summer? While the reasons behind the detrimental effects of extreme heat are layered and complex, there is a simple logic at its foundation: As a society, we continue to treat cooling as a luxury, rather than the necessity it has become in the face of rapidly accelerating climate change. Article content Effective solutions are within reach. Ontario cities such as Toronto, Mississauga and Kingston are at the forefront of debates around the adoption of maximum indoor temperature bylaws. These enforce a legal upper bound to indoor temperatures, usually around 26 degrees Celsius. While the bylaw debate proceeds, some cities are rolling out stopgap measures, where air conditioning is provided in specific cases.
