Meat that is certified organic by the U.S. Department of Agriculture is less likely to be contaminated with bacteria that can sicken people, including dangerous, multidrug-resistant organisms, compared to conventionally produced meat, according to a study from researchers at the Johns Hopkins Bloomberg School of Public Health.
The findings highlight the risk for consumers to contract foodborne illness contaminated animal products that sicken tens of millions of people in the U.S. each year and the prevalence of multidrug-resistant organisms that, when they lead to illness, can complicate treatment.
The researchers found that, compared to conventionally processed meats, organic-certified meats were 56% less likely to be contaminated with multidrug-resistant bacteria. The study was based on nationwide testing of meats from 2012 to 2017 as part of the U.S. National Antimicrobial Resistance Monitoring System, or NARMS.

A new approach to road safety that relies on design and engineering principles the Safe System approach could lead to dramatic reductions in vehicle-related deaths and injuries if implemented in the U.S., according to a report from a consortium of experts convened by researchers at Johns Hopkins Bloomberg School of Public Health and the Institute of Transportation Engineers.
The Safe System approach engineers road systems so that they are safe when used intuitively, the way people tend to use them. A Safe System minimizes the chances for mistakes by drivers, pedestrians, and bicyclists, and reduces the intensity of crashes when they do occur. This approach which may include the use of roundabouts, separated bike lanes, rumble strips, and other measures has already been applied successfully in several other countries. In Sweden, where the approach was first implemented, road deaths fell by about 67% from 1990 to 2017.
In-person schooling with inadequate mitigation measures raises household members COVID-19 risk

People living with a child who attends school in-person have an increased risk of reporting evidence of COVID-19, but teacher masking, symptom screening, and other mitigation measures in schools may be able to minimize that excess risk, suggests a study led by researchers at the Johns Hopkins Bloomberg School of Public Health.
For their study, the researchers analyzed nearly 600,000 responses from an ongoing Facebook-based COVID-19 symptom survey in the United States over two periods between November 2020 and February 2021 before vaccines were widely available in the U.S. The researchers found that those living with a child engaged in full-time, in-person pre-K-to-12 schooling were a
Study identifies risk factors for COVID-19 infection, hospitalization, and mortality among U.S. nursing home residents
Study of almost 500,000 elderly in over 15,000 nursing homes finds that risk factors for infection tend to be affected by nursing homes and surrounding communities, while risk factors for hospitalization and death depended on patient-specific factors

Risks of coronavirus infection for long-stay nursing home residents were mainly dependent on factors in their nursing homes and surrounding communities, according to a large study led by a researcher at the Johns Hopkins Bloomberg School of Public Health.
By contrast, the study found that the risks of being hospitalized with, and of dying from, COVID-19, depended more on patient-specific characteristics such as age and body mass index although the mix of factors linked to hospitalization was distinct from the mix of factors linked to mortality.
These findings will not only help doctors and other clinicians plan for the future, they will also guide policymakers and technology companies, especially as we learn more about the challenges of accessing telehealth among older patients, the uninsured, and low-income patients.

For their study, researchers from the Johns Hopkins Bloomberg School of Public Health and Blue Health Intelligence, an independent licensee of the Blue Cross Blue Shield Association, analyzed anonymized claims data drawn from 36.6 million private insurance plan members who were of working age and continuously enrolled during the study period. The claims data for the study were provided by Blue Health Intelligence.
