Food Safety Considerations In Integrated Organic Crop–Livestock Systems: Prevalence Of Salmonella Spp. And E. Coli O157:H7 In Organically Raised Cattle And Organic Feed, Joshua Nazareth, Angela M. Shaw, Kathleen Delate, Robert D. Turnbull Dec 2019

Food Safety Considerations In Integrated Organic Crop–Livestock Systems: Prevalence Of Salmonella Spp. And E. Coli O157:H7 In Organically Raised Cattle And Organic Feed, Joshua Nazareth, Angela M. Shaw, Kathleen Delate, Robert D. Turnbull

Food Science and Human Nutrition Publications

Availability of organic foods has been increasing in the United States due to consumer demand for food produced with a lower environmental footprint. Surveys show that organic consumers view organic food as safer and of higher quality, but a number of food-borne outbreaks have been linked to organic produce in recent years. This outcome suggests that improved food safety protocols are needed to ensure food safety along organic food chains. In this study, model integrated crop–livestock organic systems were established in three states (Iowa, Minnesota and Pennsylvania) to evaluate biological performance and food safety aspects. Organically raised cattle and ...


Assisting Food Processors With Food Safety Modernization Act Compliance, Jacques L. A. Overdiep, Angela M. Shaw Jun 2019

Assisting Food Processors With Food Safety Modernization Act Compliance, Jacques L. A. Overdiep, Angela M. Shaw

Food Science and Human Nutrition Publications

The Food Safety Modernization Act (FSMA) Human Food Audit Checklist was developed as a tool for assisting food processors with implementation of FSMA. This 70-page checklist incorporates Title 21 Code of Federal Regulations (CFR) Part 1 Subparts H (Registration of Food Facilities) and O (Sanitary Transportation of Human and Animal Food) and 21 CFR 117 (Preventive Controls for Human Food Hazard Analysis and Risk-Based Preventive Controls and Current Good Manufacturing Practices) with hints, comments, and definitions. The checklist was reviewed by Food and Drug Administration experts and food company personnel to validate its usefulness. It can be modified to fit ...


Development Of A Food Safety Training For A Prison Farm: Challenges And Solutions, Angela M. Shaw, Kara Helterbran Dec 2018

Development Of A Food Safety Training For A Prison Farm: Challenges And Solutions, Angela M. Shaw, Kara Helterbran

Food Science and Human Nutrition Publications

Workers on prison farms in the United States commonly grow produce and row crops and raise livestock. Teaching good agricultural practices to prisoners and prison staff increases the safety of the food produced and reduces the likelihood of an illness outbreak. We developed a food safety curriculum for use on prison farms in Iowa. In developing the curriculum, we encountered many challenges that resulted in modifications in the content and delivery method. We present the content of the curriculum and provide educators with a better understanding of challenges and potential solutions related to working with prison farms.

Objectives: We determined relationships between food behaviors and health-risk factors by acculturation among limited-income Hispanic and non-Hispanic white women. Methods: Women aged 18-49 years were recruited from income-based programs in metro-Phoenix, Arizona. Self-administered surveys in English or Spanish included demographics, a 10-item food behavior checklist, health-risk factors, food security, and acculturation. Differences by 4 acculturation/ ethnicity categories were assessed with chi-square and analysis of variance (ANOVA). We created a food behavior scale. Results: Eighty-two percent self-identified as Hispanic (N = 358), with 45% Hispanic-dominant, 25% bicultural, 12% English-dominant, and 18% non-Hispanic white for acculturation status. Food behavior checklist results showed that ...


Promoting Food Safety Awareness For Older Adults By Using Online Education Modules, Amber Roy, Sarah L. Francis, Angela Shaw, Lakshman Rajagopal Feb 2016

Promoting Food Safety Awareness For Older Adults By Using Online Education Modules, Amber Roy, Sarah L. Francis, Angela Shaw, Lakshman Rajagopal

Food Science and Human Nutrition Publications

Older adults are susceptible to and at greater risk for food-borne illness in comparison to those in other adult age groups. Online education is an underused method for the delivery of food safety information to this population. Three online mini-modules, based on social marketing theory (SMT), were created for and pilot-tested with older adults. These mini-modules were effective in promoting familiarity with food safety behaviors and were well-received, supporting the development of future SMT-based online education for this target audience.


Systematic Approach To Food Safety Education On The Farm, Angela Shaw, Catherine Strohbehn, Linda Naeve Dec 2015

Systematic Approach To Food Safety Education On The Farm, Angela Shaw, Catherine Strohbehn, Linda Naeve

Food Science and Human Nutrition Publications

Food safety education from farm to end user is essential in the mitigation of food safety concerns associated with fresh produce. Iowa State University developed a multi-disciplinary three-level sequential program ("Know," "Show," "Go") to provide a holistic approach to food safety education. This program provides knowledge on GAP (Know); guides development and documentation of food safety practices (Show); and aids in grower's readiness for third party auditing (Go). Evaluations suggest this program is effective in changing long term food safety knowledge, attitude, and behaviors. The multi-disciplinary sequential approach can be used by other Extension programs to reach.


Hybrid Food Preservation Program Improves Food Preservation And Food Safety Knowledge, Sarah L. Francis Aug 2014

Hybrid Food Preservation Program Improves Food Preservation And Food Safety Knowledge, Sarah L. Francis

Food Science and Human Nutrition Publications

The growing trend in home food preservation raises concerns about whether the resulting food products will be safe to eat. The increase public demand for food preservation information led to the development of the comprehensive food preservation program, Preserve the Taste of Summer (PTTS). PTTS is a comprehensive hybrid food preservation program comprised of online lessons and corresponding in-person workshops. PTTS participants reported increases in knowledge about food preservation food safety and recommended food preservation techniques after participating.
