Article Abstract
Objective: Commercial listings of food retail outlets are increasingly used by community members and food policy councils and in multilevel intervention research to identify areas with limited access to healthier food. This study quantified the amount of count, type, and geospatial error in 2 commercial data sources.
Methods: InfoUSA and Dun and Bradstreet were compared with a validated field census and validity statistics were calculated.
Results: Considering only completeness, Dun and Bradstreet data undercounted 24% of existing supermarkets and grocery stores, and InfoUSA, 29%. In addition, considering accuracy of outlet type assignment increased the undercount error to 42% and 39%, respectively. Marked overcount existed as well, and only 43% of existing supermarkets were correctly identified with respect to presence, outlet type, and location.
Conclusions And Implications: Relying exclusively on secondary data to characterize the food environment will result in substantial error. Whereas extensive data cleaning can offset some error, verification of outlets with a field census is still the method of choice.

The water activity of milk powders is a critical parameter for predicting quality and safety, but some retailers in the supply chain may be limited to measuring moisture content, which can be easier and more affordable. Moisture sorption isotherms relate moisture content to the corresponding water activity. In this study, moisture adsorption and desorption isotherms were determined for nonfat dry milk (NFDM) and milk protein concentrate (MPC-85) powder samples at ambient and elevated temperatures via the modernized dynamic dewpoint isotherm (DDI) method.

The global consumption of ready-to-eat (RTE) leafy green vegetables and berries has risen as consumers perceive them as safe and nutritious options. However, these foods have also been identified as sources of enteric viruses that infect the human gastrointestinal system, which are then excreted and can spread through the fecal-oral route. In Argentina, there is limited evidence on the detection of enteric viruses in food, and no legislation currently requires their detection in frozen or fresh produce intended for domestic consumption.
