Key findings

Research from several Environmental Health Specialists Network (EHS-Net) projects has led to key takeaways on restaurant food safety:

  • Restaurants with kitchen managers certified in food safety are less likely to have foodborne illness outbreaks, have better food safety practices, have better ratings and fewer critical violations on their inspections (read our summaries).
  • Posting health department restaurant inspection scores at restaurants and using letter grades for restaurant inspection results are linked with fewer foodborne outbreaks and could lead to safer restaurants (read the summary).
  • Managers can support workers staying home when sick by taking a proactive role in deciding whether sick workers should work (read the summary).
  • Retail delis can address gaps in food safety practices by encouraging kitchen manager certification and having written slicer cleaning policies (read the summary).
