As food contributes to 40% of the solid waste generated by resorts, food waste is a primary cocnern for the hospitality industry, which seeks to decrease costs in a low-margin business. Thus, industry and non-governmental organizations have begun to address the issue. While consumer demand and willingness to pay premiums for sustainable practices and green-certified destinations continues to grow, the hospitality industry struggles to provide the experience environmentally conscious consumers seek. Resorts and tourism destinations are known for overuse and abuse of resources, resulting in long-term negative social and environmental impacts to local communities. The current study sets forth a plan to assess consumer awareness of green certification programs, the importance of food waste reduction in such certification programs, and their willingness to pay premiums at certified resorts. Results will provide pertinent information about the potential benefits of third-party green certification programs to the hospitality industry.

Results from a sample of grade-level students suggest that they consumed tacos more frequently than frankfurters, hamburgers, nuggets, chicken, beef, or goat meat. The sampled students also perceived beef as more unhealthy than chicken or goat meat. Ninety-five percent of the students expressed some willingness to try new food products, and 80 percent indicated they would encourage their parents to buy goat meat products. Gender and grade levels did not affect eating frequencies of the selected meat products. However, more females perceived nuggets as unhealthy when compared to males. High-school students were also more likely to perceive nuggets as unhealthy when compared to students from elementary and middle schools.

Rising consumer interest in how food is produced has resulted in the growth of antibiotic-free meat production and consumption. The antibiotic-free classification is most prominent in the poultry market as several producers and retail-chain companies have moved their marketing in that direction. This study examines the environmental and economic impacts of withdrawing antibiotics (including animal-only ionophores) from U.S. broiler production. Two systems—conventional and 100% antibiotic-free (ABF)—are modeled, examining differences between average survivability, space requirements, days to grow-out a defined sized bird, and days between production cycles. Data were obtained from the USDA, industry sources (e.g., Agri Stats, Vantress, Aviagen), and expert knowledge. Total output is calculated to compare the average quantity of edible broiler meat produced within each system. Results reveal a decline in average production in the ABF system for a given broiler house compared to the conventional system. Compared to broilers produced in a conventional system, birds raised in a single broiler house under ABF conditions will have an annual reduction of between 50,000–100,000 lbs of edible meat (breast, legs, thighs, wings) equivalent to between 265,000–530,000 individual 3 oz. single servings. This loss represents enough to feed 600–1,000 people annually, based on average annual consumption of chicken in the United States in 2012. In order to maintain the same supply of meat under ABF conditions, a typical broiler house will require between 15,000–33,000 more marketed broilers per year. Due to the additional broilers needed, eliminating antibiotic use has an environmental impact. Compared to a conventional house, chickens raised in a single broiler house under ABF conditions will require between 185,000–390,000 additional lbs. of feed per a year; between forty-two and ninety additional acres a year to produce that feed; between 33,000 and 78,000 additional gallons of water consumed; and between 157,000 and 333,000 additional tons of manure produced. In addition, the cost to produce edible prime meat in a broiler house under ABF conditions is between $52,000 and $110,000 per year.Findings suggest that eliminating the use of antibiotics in the raising of broilers may have a negative effect on the conservation of natural resources as well as a negative economic effect via increased prices to the consumer. Results suggest the need to communicate to consumers the supportive role that prudent, responsible use of antibiotics for animal disease treatment, control, and prevention plays in the sustainable production of broilers.

We used an online survey to examine the broccoli quality requirements of East Coast wholesale and retail buyers. Buyers exhibit strong preferences for broccoli attributes such as dark green color, small bead size, and uniform heads. Buyers demand the same high quality standards for both locally grown and West Coast–grown broccoli. Natural food resellers are more open to different product conditions in local broccoli. They could be the most approachable buyers for broccoli grown in the East Coast. These results could serve as the basis for future research regarding produce buyers’ preferences for locally grown produce.

This research seeks to determine whether a new source of data from a monthly, nationwide survey of food consumers, the Food Demand Survey (FooDS), is a leading indicator of meat prices included in the Bureau of Labor Statistics (BLS) Consumer Price Index. This study relies on consumers’ expectations about prices increasing or decreasing. For most meats studied, survey-based consumer price expectations Granger cause retail meat prices. Because the BLS releases price data with a lag, the survey data can be used as a leading indicator to project future retail price changes two times before the official government reports are released.

As information regarding origin, production method, and environmental certifications characterize a progressing seafood market, scare analysis has been made to understand market responses. This study focuses on consumer preference for wild-caught and farm-raised shrimp with several attributes. These include the Homegrown By Heroes label and Best Aquaculture Practices certification, as well as other existing attributes including the Marine Stewardship Council and each state’s local label. Also considered are hypothetical labels including Community Supported Fishery (CSF) and National Oceanic & Atmospheric Administration (NOAA). This study surveys consumers in Kentucky and South Carolina while utilizing a choice experiment to elicit willingness-to-pay measures for these various product attributes. Both wild-caught and farm-raised shrimp are considered since these species have significant market potential. Like previous studies, a strong preference for fresh as well as local shrimp was found. Furthermore, preference for Homegrown By Heroes was found to be highly valued by consumers, as well as the NOAA label signifying a federally operated ecolabel. Consumers were also found to value BAP and MSC certifications, two third-party agencies currently existent in the seafood market. Marketing and policy recommendations are given based on consumer willingness to pay estimates for these various seafood attributes in both states.

This paper elucidates the impacts of the September 2005 foot and mouth disease outbreak on the Brazilian meat market for different levels of the industry (export, wholesale, and farm). The associated import ban by Russia on Brazilian meat exports is also analyzed. Results suggest that the increase in domestic supply due to the import ban generated downward pressure on prices at all levels for pork and chicken. Meanwhile, export beef and wholesale beef prices underwent ambiguous and positive changes, respectively, while farm level prices only recovered after the removal of the import ban.

Prices of 14 nutrient-dense and energy-dense food items were collected at full-service grocery stores in 2009. Using econometric models that included both supply and demand factors, analysis was conducted to determine whether income and demographic variables had differential impacts on the pricing of energy-dense versus nutrient-dense foods. Results showed that the store’s being part of a supercenter was the most important pricing determinant for both food types. All other independent variables were significant for only one to three food items. Very limited statistical evidence was found to support neighborhood per-household income having differential impacts on nutrient-dense versus energy-dense food pricing.

This paper investigates the degree to which glass bottled milk is an environmentally friendly alternative. A recent life cycle assessment for fluid milk packaging alternatives is utilized to quantify the environmental costs associated with each packaging type. We conduct a sensitivity analysis to identify the return and reuse rates under which the glass bottle has a lower environmental impact than the alternatives. With eight reuses and 95 percent return rate, glass bottled milk has a lower environmental cost than the alternatives. Twelve reuses and a 100 percent return rate is necessary for glass packaging to have the lowest social cost.

Our primary objective is to assess the role of culture by linking college students’ current consumption of fruits and vegetables with their produce consumption levels while with family. Using a Tobit model, we analyzed data from an online survey with college students. Family consumption of fruits was highly predictive of the individual’s consumption of fruits. For each unit increase in the reported consumption of fruits (vegetables) with the family, the respondents’ fruit (vegetable) consumption at school increased by 0.65 (0.30) units compared to the base consumption level of 1.95 (1.82) times of fruit intake per day.
