Meatless Monday is a global movement that encourages people to reduce meat in their diets for their own health and the health of the planet. We conducted a comprehensive review of primary and secondary sources and archival material documenting the origins, historical roots, and growth of Meatless Monday and simultaneous developments in public health. Sources for the paper included publications of the US Food Administration and articles and media identified using searches of ProQuest Historical Newspapers, Newspapers.com Academic, ProQuest US Newsstream, ProQuest Canadian Newstream, ProQuest International Newsstream databases, and Google.com. Meatless Monday was conceived by the advertising executive and public health advocate Sid Lerner in 2003, inspired by the meatless days observed during World War I and II. Meatless Monday grew steadily from 2003 to 2023 through advocacy by food writers, talk show hosts, and celebrity chefs, and through participation by schools, cities, restaurants, corporations, and institutions worldwide. School systems began to observe Meatless Monday, such as Baltimore City Public Schools in 2009 and New York City Public Schools in 2019. Meat-Free Monday campaign was launched by Paul McCartney and his daughters in 2009 in the United Kingdom. The Humane Society of the United States became an advocate for Meatless Monday and helped institute it in >200 US school systems. From 2003 to 2023, Meatless Monday spread to over 40 countries and was observed in public schools in countries such as Brazil, Ireland, and Belgium. Findings regarding high meat consumption and its adverse effects on health, high greenhouse gas production and environment degradation, and problems with animal welfare under conditions of industrial food animal production emerged during the same period and influenced many to advocate Meatless Monday. Meatless days of World War I and II were driven by patriotic motivations to provide food for the US troops and the Allies in Europe, whereas motivations for observing Meatless Monday were largely related to concerns regarding personal health, the environment, and animal welfare. Meatless Monday grew from relatively humble origins to a highly recognized worldwide movement with wide appeal as a way to begin reducing meat consumption for personal and planetary health.

Many food policy councils, food and agriculture-oriented groups, coalitions, organizations, funders, nonprofits, decision-makers, government depart­ments, and other entities work to address local food system issues and inequities that negatively affect human, animal, and planetary wellbeing. In this article, we summarize and reflect on the pro­cess of creating an open-access food system indica­tors database. Our goal has been to create a library of indicators from which groups can draw when assessing their local food system, identifying improvement opportunities, and evaluating their efforts. The indicators were extracted from seven sources selected to cover a wide range of food sys­tem elements and pertinent topics, including nutri­tion, agricultural production, racial equity, health outcomes, environmental impacts, and economics. Our work can contribute to needed research on monitoring and evaluating food system attributes and changes, developing a common set of indica­tors that groups can use to track food systems across places and over time and to assess racial equity, justice, and fairness in the food system.

BACKGROUND:Seafood has a nutritional profile that can be beneficial to human health, which gives it a role to play in healthy diets. In addition, because its production and harvesting can have fewer environmental impacts than some forms of animal protein, it can contribute to sustainable diets. However, the positive health and environmental outcomes are not guaranteed-they depend on how seafood is prepared and served and whether it is sourced from sustainable fisheries and aquaculture industries.OBJECTIVES:We examined the availability and nutritional attributes of seafood meals at chain restaurants in the United States. We assessed nutritional attributes by store type and geography. We also assessed menu labeling for species, production methods, and origin.METHODS:The study population was 159 chain restaurants with 100,948 branch locations in the United States. Data were harvested from online restaurant menus, and the nutritional profile of seafood meals was calculated.RESULTS:The average seafood menu item provides up to 49-61% of the total daily limit of saturated fat, 65% of the total daily limit of sodium, and 58-71% of total daily protein requirement for adult men and women. Restaurant chains located in the Deep South and Ohio River Valley, and casual dining chains nationally, carry seafood meals with more total calories and saturated fat per 100 g than other regions or chain types. Most menu items did not list origin or production methods, which is information that would help consumers make informed decisions.CONCLUSIONS:The added ingredients and cooking methods used at chain restaurants can attenuate the health benefits of seafood. We recommend reformulating menus to reduce portion sizes, total calories, added fat, and sodium content per meal and to improve consumer-facing information about origin and production methods.

Seafood is a highly traded commodity and 71% of the United States (U.S.) supply is imported. This study addresses questions about imported seafood safety and compares risks of outbreaks and recalls across countries of origin, species, and stages of the supply chain. We found that where seafood comes from does not play a major role in risk. Risk is a function of the activities happening at each stage of the supply chain, inherent riskiness of some products or processes, and ?pass through? risks introduced at upstream and midstream stages of the supply chain. Dominant farmed species (shrimp, tilapia, catfish) became less risky as they move along the supply chain toward consumers. We recommend investments in agencies overseeing food safety and health, enhanced traceability within supply chains, and more open government datasets that support systems-level analyses.

Vibrio bacteria can accumulate in molluscan shellfish and cause human diseases. The United States (U.S.) has implemented Vibrio Control Plans to mitigate risks associated with these bacteria, which include time and temperature requirements for post-harvest processing and maintaining an unbroken cold chain. In this study, we tracked the performance of cold chains for U.S. farmed oysters distributed nationally and internationally using temperature sensors. Boxes and bags of oysters (n = 125) were shipped from farms in Washington State and the Chesapeake Bay to 143 unique businesses in 20 U.S. states, Washington D.C., and Hong Kong, China. Eighty-one percent of the temperature sensors were returned with usable data. The average product temperature among all participants was 4.4 ± 2.7 °C (40 ± 5 °F), which is 5.6 °C (10 °F) cooler than the 10 °C (50 °F) guidance criterium established by the U.S. government. There were spikes in temperature in some shipments: 18% of shipments (16/91) experienced oyster temperatures above 10 °C for one hour or more, and the median time spent out of temperature control was 2.5 h. We modeled V. parahaemolyticus abundance using temperature sensor data and 75% (68/91) of shipments had a net decrease in V. parahaemolyticus abundance in the cold chain. There are opportunities for improvements in cold chain performance in the shellfish industry and related businesses. In the discussion we provide recommendations for oyster producers related to product cooling, for businesses that handle shellfish, and for government and industry groups to develop guidance for shipping by air, among other issues.

The aim of this study was to explore United States (U.S.) seafood consumption patterns, food sourcing, expenditures, and geography of consumption. We analyzed seafood intake and food sourcing using the National Health and Nutrition Examination Survey (NHANES) cycles 2007–2008 to 2015–2016 for US adults ≥19 years old (n = 26,743 total respondents; n = 4957 respondents consumed seafood in the past 24 h). Seafood expenditures were extrapolated by combining NHANES with three other public datasets. U.S. adults consumed 63% of seafood (by weight) at home. The top sources of seafood (by weight) were food retail (56%), restaurants (31%), and caught by the respondent or someone they know (5%). Sixty-five percent of consumer expenditures for seafood were at restaurants and other “away from home” sources while 35% were at retail and other “at home” sources. Slightly less than half of overall U.S. food expenditures are “away from home,” which is much lower than for seafood, suggesting that consumers have very different spending habits for seafood than for an aggregate of all foods.

Temperature-controlled supply chains (cold chains) require an unbroken chain of refrigeration to maintain product quality and safety. This study investigated cold chains for farmed oysters raised in the Chesapeake Bay, one of the largest shellfish-growing regions in the United States, and sold live to the half-shell market in surrounding states. Temperature sensors were used in boxes of oysters from February to September 2017, which generated 5,250 h of temperature data. Thirty-nine businesses participated in the temperature sensor study, and 26 of those businesses participated in interviews to further understand how cold chains function. Internal oyster temperatures were measured above 50°F (10°C) for over 1 h in 19% (7 of 36) of shipments, which is a temperature that exceeds National Shellfish Sanitation Program criteria. The highest internal oyster temperature recorded in any shipment was 54.5°F (12.5°C). Some parts of the cold chain had difficulty maintaining storage temperatures below 45°F (7.2°C) in warmer months when Vibrio control plans were in effect. We modeled the effects of temperature on Vibrio parahaemolyticus. The model predicted moderate bacterial growth before oysters were under temperature control, but cold chains prevented further bacterial growth and provided a moderate drop-off in V. parahaemolyticus abundance.

Farmed oysters are one of the most valuable aquacultured products in the United States (U.S.), are highly perishable, and increasingly shipped live year-round. Supply chain actors must work together to bring refrigerated oysters to market quickly, while maintaining product value, safety and traceability information. In light of these demands, this study assesses the performance and conduct of supply chains for U.S. farmed oysters (Crassostrea virginica, C. gigas). Over the two-year study period, we conducted interviews with 56 businesses and tracked 125 oyster shipments from two major growing regions in the U.S. through six different types of supply chains. We hypothesized that direct and intermediated supply chains would perform differently in terms of time-to-market, product temperature in cold chains, compliance with temperature regulations, and modeled risks from Vibrio parahaemolyticus. Intermediated supply chains, by their definition have more connections than direct supply chains, and we found this introduces a longer time-to-market and a higher incidence of time and temperature abuse. However, these factors did not lead to greater modeled V. parahaemolyticus risks. Participants in both direct and intermediated supply chains were aware of the importance of traceability and felt uniformly positive about their ability to perform recalls. A common concern was the speed of government-imposed recalls, which can be declared by regulators after the affected live oysters are consumed. Members of these supply chains play different roles in maintaining the cold chain, possess different levels of information related to traceability, and describe different levels of trust with other supply chain actors. This paper contributes to a growing body of knowledge on supply chains for seafood and their critical, and sometimes overlooked, role in larger food systems.

The objective of this study was to measure the reliability of an index to assess healthy food in food stores. Food stores across Baltimore City were assessed using the Healthy Food Availability Index-Brief (HFAI-B) tool and resulting HFAI-B score. Reliability was measured using the Pearson correlation for the HFAI-B score, and Cohen’s Kappa for other binary and categorical store parameters. All items included in the HFAI-B score had high inter-rater and test-retest reliability. The Pearson Correlation coefficient for HFAI-B scores between and within observers was very high. The HFAI-B is a reliable measure to assess the availability of healthy foods in food stores.

CONTEXT:Recreational fishing is regulated in 2 broad ways: natural resource-based management of fish stocks referred to here as "catch regulations," and public heath-based fish consumption advisories to reduce risks to humans from exposures to pollutants referred to as "consumption advisories."OBJECTIVE:To examine the extent to which state regulatory agencies present recreational fish catch regulations and consumption advisories together and develop an ecologically based, public health argument for why these fishing regulations and advisories could be joined.DESIGN:State-level catch regulations and consumption advisories were collected from 50 US states and analyzed for a variety of factors.MAIN OUTCOME MEASURE:Correlation between catch regulations and consumption advisories, by aquatic animal species and taxonomic family, and by state, were the main outcome measures.RESULTS:State-level catch regulations were strongly predictive of state-level consumption advisories, by species (R = 0.87) or taxonomic family (R = 0.91). Within each state, however, fish catch regulations and consumption advisories were presented together in less than half of fishing guides.CONCLUSION:Fish advisories and regulations are often produced by separate state regulatory agencies, indicating an opportunity for interagency collaboration to improve health communication messaging regarding recreational fishing and self-caught fish consumption.
