Assessing Employee Health Policies for Reporting and Excluding Ill Food Employees in Restaurants within the United States.

ABSTRACT: Preventing ill food employees from spreading pathogens to food and food contact surfaces remains an important objective of retail food safety policy in the United States. Since 2005, the U.S. Food and Drug Administration (FDA) has recommended food establishments implement employee health policies that include requirements for the exclusion or restriction of ill food employees and reporting, to the person in charge, symptoms or diagnosis of certain diseases transmitted by food. However, the incorporation of this recommendation has not been widely studied. The purpose of this exploratory study was to assess the presence and prevalence of employee health policies at fast-food and full-service restaurants in the United States. More than 50% of fast-food and full-service restaurants were found to have nonexistent employee health policies for each of the five recommended components specified in the FDA Food Code. Results showed 17.41% of fast-food restaurants and 12.88% of full-service restaurants had all five recommended components. Moreover, most restaurants with all five recommended employee health policy components were part of a multiple-unit operation and were found to have more developed food safety management systems than restaurants with none of the recommended components. Further attention and research into the impediments associated with developing and implementing employee health policies in restaurants is warranted.

Temperature and pH affect copper release kinetics from copper metal foil and commercial copperware to food simulants.

Copper (Cu) metal and alloys are used in cookware and other food contact surfaces due to their desirable properties for various applications. However, Cu metal can ionise and subsequently transfer to food and beverages under certain conditions. Here, we tested how pH and temperature affected Cu release kinetics using model systems utilising Cu metal foil and commercially available copperware. Cu foil and copperware were exposed to food simulants composed of 3% (w:w) aqueous solutions of citric acid, malic acid, acetic acid, or deionised (DI) water at temperatures ranging from 4°C to 60°C. An additional pilot experiment tested how simulated long-term cleaning affected subsequent Cu release from lined and unlined copperware to 3% citric acid. Food simulants were then analysed by ICP-MS for total Cu. After 180 min, incubation of Cu metal foil with acid-containing food simulants at 4°C resulted in Cu release ranging from 8.7 - 14.0 µg cm-2, while 21.5-38.1 µg cm-2 was released at 60°C. In contrast, Cu transfer from metal foil to DI water was relatively low, with <0.6 µg cm-2 released after 180 min at 60°C. With citric acid food simulant, lined copperware released between 0.6 and 3.0 µg Cu cm-2 over 180 min at the set temperatures, while unlined copperware released approximately 25-45 fold higher amounts of Cu (26.9-74.6 µg cm-2) over this same time period. In contrast, use of DI water food simulant resulted in Cu release of <0.1 µg cm-2 for the lined copperware and <2 µg cm-2 for the unlined type. No significant effect of simulated long-term cleaning on Cu release from copperware was observed. These data indicate that Cu release is affected by temperature and pH, and that specific steps can be taken to limit Cu metal release from food contact surfaces to foods and beverages.

Food Safety Management Systems, Certified Food Protection Managers, and Compliance with Food Safety Practices Associated with the Control of Listeria monocytogenes in Foods at Restaurants.

HIGHLIGHTS: Proper cold holding and date marking practices help control Lm growth in foods. Most restaurants had ≥1 instance of improper cold holding. Less than 50% of all cold holding observations were found to be out of compliance. Restaurants in areas requiring date marking of food were more likely to date mark. CFPM did not predict out-of-compliance observations when FSMS effects were considered.
