![]() I'm not sure I understand why oats would be more susceptible to contamination than other gluten-free crops, but there is enough concern about this to confirm that it is a problem. Apparently, that tends to leave leftover gluten behind in the soil.Įven if the oats safely leave the field without gluten, there are still issues of possible contact with gluten during the transportation from the farm and then in the factory where they are processed. Oats are grown in fields where crop rotation is common, and they can be grown in a field that was previously used for wheat. "There can be gluten contamination starting just from the field," Stewart said. After that first year, you can introduce oats back into your diet and see if you have a reaction. ![]() "We recommend they don't eat oats for a year," said Melissa Stewart, a clinical dietitian at the Mayo Clinic in Jacksonville. Department of Agriculture, Penn State Extension and the College of Agricultural Sciences supported this research.Still, celiac experts at the Mayo Clinic advise caution with oats when starting a gluten-free diet. "This study should be of interest to researchers, regulatory personnel and food industry professionals who are seeking ways to evaluate the food safety behaviors of food handlers," he said. These results demonstrate, Machado explained, that use of a smartphone for data collection in a retail setting might not be perceived as an evaluative activity and that its application during direct, concealed observations could minimize behavioral changes among subjects being observed. "An observer can just pretend to be texting or fiddling with the phone, while monitoring the interactions between customers and workers in retail establishments, such as supermarket delicatessens." "We are so into our phones today, and everyone has one and carries it around, so it easily can be used as a nonthreatening tool to make direct, concealed behavioral observations, and no one will ever realize you are doing it," he said. Ninety-five percent of participant responses indicated that images of clipboard use in a retail setting suggested evaluative activities - research, inspection, and so forth - whereas none of the participants indicated that images of smartphone use in the same environment suggested evaluative activities, said Robson Machado, a doctoral candidate in food science. Participants viewed images of individuals using either a smartphone or a clipboard in a retail environment and provided open-ended responses. To evaluate the use of smartphones as inconspicuous data collection tools, the researchers developed and disseminated a short survey to assess public perceptions of smartphone use in a retail setting. The app allows observers to easily add photos, audio, videos and open-ended notes to their reports. ![]() The researchers, who recently published their findings in the journal Food Protection Trends, worked with a smartphone-application developer to create an app that includes features needed to document direct concealed observations of food handlers, including the creation of checklists to record aspects such as hand hygiene, the adequacy of hand-washing facilities, the temperature in coolers holding ready-to-eat foods and the presence of potentially hazardous foods. ![]() "In our research, we describe a newly developed smartphone and tablet application for use as a data collection tool for direct concealed observations." "Direct concealed observations have been used to minimize the Hawthorne Effect during observational data collection in various settings, but some limitations can include the need to memorize observations or take notes out of sight of those being observed," said Cutter, a food safety specialist with Penn State Extension. Those changes - known as the Hawthorne Effect - can render such observations meaningless. However, if surveillance is not concealed, it can result in unintended behavioral changes, according to Catherine Cutter, professor of food science. That is the conclusion of food science researchers in Penn State's College of Agricultural Sciences, who studied whether phones could be used in place of the traditional clipboards to improve the quality of data collection related to food safety observations.įood safety practices used by food handlers are often monitored for research, inspection and regulatory purposes. That pervasiveness allows a phone application to be used in direct, concealed observations without alerting the people being observed. Smartphones are so ubiquitous, and text messaging and social media activities so common in public places, that no one questions what anyone does with their phone. ![]()
