The Food and Drug Administration’s third annual summary of activity on the Reportable Food Registry showed more than 220 initial reports were filed in the system about food safety concerns.

According to a 31-page summary, covering the period from Sept. 8, 2011, to Sept. 7, 2012, several reports from food makers directly helped prevent food safety outbreaks.

The FDA document also revealed more than 600 subsequent reports from suppliers or recipients of a food that had been already reported in the registry, according to a news release from the agency. The FDA said there were 262 amended reports filed to correct or add information to previously submitted reports.

The FDA said the Reportable Food Registry is an important tool in the agency’s early detection system. The agency said there were three instances where submissions alerted the agency to public health issues early so products could be removed from commerce.

One of those instances involved fresh produce. The FDA report said an unidentified California onion processor was notified by FDA that the Canadian Food Inspection Agency had tested and found its exported product positive for Listeria monocytogenes contamination. As a result, the agency said potentially dangerous products were removed from the marketplace.
