Slow cooling of hot foods is a common pathogen proliferation factor contributing to restaurant-related outbreaks. The Food and Drug Administration (FDA) model Food Code provides guidelines on the time and temperatures needed for proper cooling and recommends several methods to facilitate rapid food cooling. Restaurants continue to struggle with proper cooling even given these guidelines (Hedeen & Smith, 2020). Research summarized in this guest commentary indicates that portioning foods into containers with a depth of <3 in. and ventilating the containers during the cooling process promote rapid cooling. Restaurant operators and health department inspectors could use these cooling methods to maximize cooling efforts. Additionally, a simple method (using a mathematical equation) could help restaurant operators and inspectors to estimate the cooling rates of foods. This simple method uses only two food temperatures taken at any two points in the cooling process (using the equation [Log(T₁ - T_df) - Log(T₂ - T_df)]/δt) to estimate whether the food is expected to meet FDA cooling guidelines. This method allows operators and inspectors to identify foods unlikely to meet FDA guidelines and take corrective actions on those foods without having to monitor food temperatures for the entire cooling process, which typically takes 6 hr. More research is underway to further refine aspects of this method.

This first article in a series of three on land reuse highlights sustainable brownfields redevelopment in Europe. Sustainability is a key European concept. Europe's densely populated urban areas are facing specific challenges that include urban sprawl and environmental pollution. Redeveloping brownfields, or reusing the abandoned built landscape, can positively impact the economic, social, and environmental health security of cities. Many European Union (EU) cities benefit from policy and financial assistance in renovating their urban areas. This article reviews the EU's policy and funding frameworks that support sustainable brownfields redevelopment. Brownfield site problems are common to many countries in Europe and around the world, and this article aims to share knowledge and resources that support the transformation of these abandoned or underused areas into public or private uses.

Beginning in 2016, the Agency for Toxic Substances and Disease Registry (ATSDR) and the National Environmental Health Association (NEHA) launched a partnership to create a free online course with the goal of building capacity within communities to help remediate and redevelop brownfields sites. Brownfields are land reuse sites often contaminated by harmful chemicals or redeveloped without proper environmental oversight. Due to their potentially hazardous status, brownfields sites can lead to harmful exposures in humans while accentuating and often exacerbating socioeconomic disparities within their communities. As a result of this partnership, NEHA and ATSDR launched the Environmental Health and Land Reuse (EHLR) Certificate Program in 2020. The Journal is pleased to feature this column to highlight an example of how the EHLR Certificate Program was used to build understanding and increase knowledge on this important topic within environmental health students. The findings and conclusions in this column are those of the authors and do not necessarily represent the views or official position of NEHA, ATSDR, or the Centers for Disease Control and Prevention. Furthermore, verbal permission was given by the students to use their work in this column.

Harmful algal blooms (HABs) are the rapid growth of algae that can produce toxic or harmful effects in people and animals. Potential health effects include respiratory illness, gastrointestinal illness, skin and eye irritation, and sometimes more severe toxic effects such as liver damage. Defining HAB exposure and related illness is challenging for many reasons, including characterizing the exposure. Large electronic health record databases present an opportunity to study health encounters specifically related to HAB exposure through querying medical diagnostic codes. We queried the MarketScan Research Databases between January 2009 and April 2019 for use of the International Classification of Diseases (ICD) codes for HAB exposure. We found a total of 558 records that used either the ICD-9 or ICD-10 code for HAB exposure. Respiratory illness was most commonly reported along with the HAB exposure code. Use of HAB exposure codes showed seasonal fluctuations during 2012-2019. We found that although the HAB-related ICD-9 and ICD-10 codes were used infrequently, they were most often recorded during bloom seasons in warmer months. This analysis is the first that utilizes a large-scale national database of de-identified health records to understand the use of medical diagnostic codes related to algae exposure.

In October 2018, the Centers for Disease Control and Prevention was notified of a cluster of Legionnaires' disease cases in workers at a racetrack facility. The objective of the resulting investigation was to determine the extent of the outbreak and identify potential sources of exposure to halt transmission. Case-finding and interviews were conducted among symptomatic racetrack workers who were known to be at the facility within 14 days prior to symptom onset. An environmental assessment of the facility and surrounding area was conducted for sources of potential Legionella exposure. In total, 17 legionellosis cases were identified. The environmental assessment revealed a poorly maintained hot tub in the jockey locker room as the most likely source. Further investigation identified deficiencies in the facility's ventilation systems, which suggested a transmission mechanism for workers who never entered the locker room floor. Considering indirect exposure routes via air handling systems can be useful for source identification and case-finding in legionellosis outbreaks.

As part of our continued effort to highlight innovative approaches to improve the health and environment of communities, the Journal is pleased to publish regular columns from the Agency for Toxic Substances and Disease Registry (ATSDR) at the Centers for Disease Control and Prevention (CDC). ATSDR serves the public by using the best science, taking responsive public health actions, and providing trusted health information to prevent harmful exposures and diseases related to toxic substances. The purpose of this column is to inform readers of ATSDR's activities and initiatives to better understand the relationship between exposure to hazardous substances in the environment, its impact on human health, and how to protect public health. The conclusions of this column are those of the author(s) and do not necessarily represent the official position of ATSDR or CDC.

This article will identify the state of science on the generation, production, and transport of perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Additionally, this article will focus on the transport of these environmental contaminants through air sources. It is important to explore why air exposure is critical to bring awareness to a problem that is not always immediately apparent. From a biological standpoint, clean air is necessary to sustain healthy life. Thus, it is key to understand the environmental transport of chemicals such as PFOS and PFOA with regard to their ability to migrate (i.e., air to water and water to air) and thus create unsafe air. The fluorinated backbone of these substances is both hydrophobic and oleophobic/lipophobic, while the terminal functional group is hydrophilic (water loving). Therefore, PFOS and PFOA compounds tend to partition to interfaces, such as between air and water with the fluorinated backbone residing in air and the terminal functional group residing in water. This article will identify opportunities for research to further the understanding of their potential impacts to human health.

We examined mold clean-up practices in a general population (not selected on history of natural disaster). We used a population-based survey (n= 3,624) to assess associations between sociodemographic/ housing/ respiratory health variables and mold clean-up, PPE use, and cleaning agent use. Bleach was the most commonly used cleaning agent with approximately 90% of residents reporting using bleach alone or with other agents. More respondents used gloves (76%) than any other PPE. The use of PPE varied; 42% of bleach users wore a breathing mask/respirator compared with only 19% of soap and water users. Hispanic populations frequently reported mold clean-up. Bleach use was less likely in the West and among Asians. Although "Green" products were rarely used, Asians were more likely to use them. Bleach was the most commonly used cleaning agent for mold, and PPE use was common when using bleach, supporting the need for current CDC safe use recommendations.

Internships are an essential component of preparing prospective college graduates for entering the practice-based field of environmental health (EH). EH professionals continually encounter events or hazards of high complexity and impact, and many experienced EH professionals are expected to retire within the next several years. Efforts are needed to ensure a supply of highly qualified and prepared graduates is available to sustain and strengthen the EH workforce. The National Environmental Public Health Internship Program (NEPHIP) addresses this need by supporting health department internships for EH students of academic programs accredited by the National Environmental Health Science and Protection Accreditation Council. We conducted an assessment to examine former NEPHIP intern and mentor experiences and perspectives on 1) how well the internships prepared interns for careers in EH and 2) to what extent the internships provided value to the host health department. Overall, the internships appeared to provide EH students with a well-rounded professional and practice-based experience, while health departments benefited from hosting interns with a foundational knowledge and college education in EH. Promoting the value of public health department EH internships could encourage more students and graduates to seek internship or employment opportunities with health departments, ultimately strengthening the EH workforce.
