Los casos de hepatitis B podrían aumentar bajo las nuevas pautas de la vacuna, según un estudio

Kayem Foods Inc. has initiated a voluntary recall of more than 1.5 million pounds of ready-to-eat meat and poultry products due to potential temperature abuse during storage. The United States Department of Agriculture’s Food Safety and Inspection Service announced the action on October 17. The affected items include bacon, deli meats, hot dogs, corned beef, chicken sausage, and turkey breast. According to the agency, the products may have been stored in a warehouse cooler with inconsistent temperatures, rendering them potentially unsafe for consumption. The recall stems from an incident discovered on October 1, when a retail customer reported receiving warm products. Subsequent investigations revealed that the specific batch of goods had been held in a facility where cold chain integrity was compromised. Federal guidelines mandate that cold food be maintained at or below 40 degrees Fahrenheit. Temperatures exceeding this threshold allow for bacterial growth and spoilage, which can lead to foodborne illnesses. Even if the meat is cooked to standard internal temperatures afterward, authorities warn that safety cannot be guaranteed. The implicated products bear establishment numbers EST. M/P 7839, EST. P 20935A, and EST. M 9520 inside the USDA inspection seal. Production dates for the recalled items fall approximately between March 31 and October 7. Distribution was widespread, reaching retailers across the United States as well as markets in Hong Kong. Consumers are advised to inspect their refrigerators for these specific codes and production windows. Melissa Vaccaro, a senior food safety program specialist at the National Environmental Health Association, emphasized that visual or olfactory checks are insufficient for determining safety. She noted that food can harbor dangerous microorganisms without exhibiting signs of decay such as odor or discoloration. Consequently, tasting questionable food to assess its viability is strongly discouraged. The Food Safety and Inspection Service instructs consumers to discard the recalled meat or return it to the point of purchase. Kayem Foods has established a customer service channel for inquiries, available Monday through Friday from 7:30 a.m. to 4 p.m. Eastern Time via telephone or email. Separate from the meat recall, public health discourse is intensifying regarding changes to infant immunization protocols. A study published in the Annals of Internal Medicine examines the potential epidemiological consequences of recent policy shifts by the Centers for Disease Control and Prevention. In December 2025, the CDC moved away from the routine recommendation for administering the first dose of the hepatitis B vaccine within 24 hours of birth for infants born to mothers who test negative for the virus. Instead, the new guidance advocates for a shared decision-making model, allowing parents and clinicians to choose between an immediate post-birth dose or delaying the first injection until the infant reaches two months of age. Infants born to mothers with positive or unknown hepatitis B status remain subject to the immediate dosing recommendation. Dr. Amir Mohareb, an infectious-disease researcher at Harvard Medical School and Massachusetts General Hospital, led the computational analysis. The team used modeling to simulate the infection trajectories of 3.6 million children born in a single year over their first two decades of life. The simulations compared scenarios where previous universal birth-dose mandates were maintained against scenarios reflecting the new shared-decision framework. The data indicated that if vaccination rates dropped to an estimated 26 percent under the new model, chronic hepatitis B cases would surge by 225 percent. Even in a scenario where 75 percent of infants received the delayed dose at two months, chronic cases rose by 19 percent compared to universal birth dosing. Mohareb stated that the findings aim to provide empirical weight to ongoing debates within professional societies and state governments. He argued that repeating historical clinical trials to validate current practices is unnecessary, as decades of prior research have already confirmed the efficacy of the existing approach. The researcher warned that sustained lower vaccination coverage could result in thousands of new infections annually, leading to long-term chronic conditions, increased cancer risks, and substantial healthcare costs. Simultaneously, concerns are rising over an uncontained avian influenza outbreak at a mink farm in Utah. ProPublica reporting indicates that the H5N1 virus has been spreading unchecked at C&T Fenn Farms, located west of Provo, since mid-August. The farm raises thousands of mink for the fur trade. While the virus has primarily affected avian populations, killing two humans who contracted it from sick animals, experts warn that mink serve as a critical intermediate host. Their respiratory systems share cellular similarities with humans, making them susceptible to mutations that could facilitate transmission to people. State veterinarian Amanda Price acknowledged the severity of the situation but cited the lack of federal regulations specifically governing mink health during outbreaks. Unlike poultry flocks, where a single positive test triggers mandatory culling and reimbursement, no such protocol exists for mink. Price expressed empathy for the farm owner, describing the outbreak as devastating to his livelihood. However, flu specialists criticized the government response as irresponsible, noting that officials prioritized economic interests over public health safeguards. Records indicate that despite CDC guidance to monitor farm workers, state authorities declined to test staff members, including one individual presenting symptoms that warranted examination. Experts caution that the current conditions create a high-risk environment for viral mutation, potentially paving the way for a human pandemic.
