<< Risk Profile: Pathogen and Filth in Spices

To reduce the risks of foodborne illness from contaminated spices, the FDA has been addressing spice safety on several fronts, including as part of new rules, under the Food Safety and Modernization Act (FSMA), to establish preventive controls in the food supply chain, for both domestically produced and imported food. As part of the effort to learn more about the public health risks associated with spices and help develop plans to improve the safety of spices, the FDA also developed a draft risk profile, which was released in October 2013. On January 13, 2018, the FDA issued an update to its 2013 draft risk profile on spices to include analysis of a two-year, nationwide study to collect data on the presence of Salmonella in retail packages that you would find in supermarkets, ethnic markets, discount stores, and on the internet. The data demonstrate that the prevalence of Salmonella in nine out of 11 types of retail spices in the U.S. was significantly lower than that for shipments of spice at import. The findings are consistent with public comments from the domestic food industry that responsible manufacturers apply a pathogen reduction treatment to many spices after entering the U.S., prior to retail sale.

Questions & Answers

1. What has the FDA learned about the safety of spices?

To learn more about the public health risks associated with spices and help us in developing plans to improve the safety of spices, we developed a draft risk profile , which we released in October 2013 and updated in 2018. The objectives of the risk profile included describing the nature and extent of the public health risk posed by the consumption of spices in the U.S., describing and evaluating current strategies used to reduce the public health risk posed by the consumption of spices, identify additional strategies that could be used, and identifying critical gaps in the data we currently have available to us.

2. What did the risk profile find?

The 2013 draft risk profile determined that the presence of pathogens, such as Salmonella, and filth in spices is a systemic challenge and that the problem relates in part to poor or inconsistent use of appropriate controls to prevent contamination. Spice shipments from 79 countries were examined for Salmonella, and we found that 37 of the 79 countries had Salmonella-contaminated shipments, indicating that contamination of spice shipments with Salmonella is not limited to just a few source countries. Spice shipments offered for entry into the U.S. had an overall prevalence for Salmonella of approximately 6.6 percent during the 2007 to 2009 fiscal years, about twice the average prevalence of all other imported, FDA-regulated foods. We also found that approximately 12 percent of the spice shipments offered for entry to the U.S. during a three-year period (FY 2007 to FY 2009) were adulterated with filth such as insects and animal hair, which can result from inadequate packing or storage conditions.

However, we noted in the study an important data gap in that we were missing key information about the level of contamination of spices at retail in the U.S. When we began conducting the risk profile, we asked the public for any data but did not receive information about contamination rates at retail. Because many imported spices are treated after entry to the U.S. to reduce contamination before they are sold to consumers, we knew that the 6.6 percent contamination rate found at the import level did not reflect what was actually reaching consumers. We needed retail data to better evaluate the true risk to consumers.

3. Do you now have the retail data?

Yes, we conducted a two-year, nationwide study to collect data on the presence of Salmonella in retail packages that you would find in supermarkets, ethnic markets, discount stores, and on the internet. The data demonstrated that the prevalence of Salmonella in nine out of 11 types of retail spices in the U.S. was significantly lower than that for shipments of spice at import. The findings are consistent with public comments from the domestic food industry that responsible manufacturers apply a pathogen reduction treatment to many spices after entering the U.S., prior to retail sale.

Domestically produced and imported spices were included in the 7,249 samples collected of the following spices: basil, black pepper, oregano, paprika, red pepper (capsicum), coriander, cumin, curry powder, garlic, sesame seed and white pepper.  Except for dehydrated garlic and basil (for which statistical power was limited), Salmonella prevalence was significantly lower in retail samples than estimated prevalence for shipments of imported spice offered for entry to the U.S.

4. Is there a difference in safety between imported and domestic spices?

We do not have contamination data specifically for domestically produced spices. Most of the U.S. spice supply is imported, with some exceptions. Most of the dehydrated onion used in the U.S. is produced in the U.S. U.S. farms also produce significant amounts of the U.S. supply of dehydrated garlic, capsicum and mustard seed.

5. What steps is FDA taking to improve the safety of spices?

The FDA Food Safety Modernization Act (FSMA), which we are now implementing, will help us improve spice safety because the FSMA rules focus on preventing hazards and on tightening controls in the supply chain. The FSMA rules address both domestically produced and imported foods. For example, the preventive controls rule requires food facilities, including those that manufacture spices, to conduct a hazard analysis, identify hazards reasonably likely to occur, and establish preventive controls for such hazards. The foreign supplier verification rule requires that importers verify that the foods they import are produced using processes and procedures that ensure the same level of safety as food produced in the U.S. Produce safety requirements may apply to certain types of spice source plants. Further, FDA is establishing a program for the accreditation of third-party certifiers to conduct rigorous, objective food safety audits.

In addition, in recent years, the agency has increased its inspections of spice manufacturing facilities.

FDA also works closely with its partners in other countries to share information on ways to improve spice safety and has staff permanently stationed in China, India, Europe, Latin America, Middle East and North Africa, and Sub-Saharan Africa. In India, the leading country of origin for U.S. spice importation, the FDA maintains offices in New Delhi and Mumbai. FDA is working with several partners to develop a training center focused on supply chain management for spices and botanical ingredients. The goal of the center is to establish a cadre of in-country experts who can offer training in all aspects of food safety management throughout the supply chain. FDA scientists also will participate in the newly formed Codex Committee on Spices and Culinary Herbs. Codex is an international organization that sets food safety standards, guidelines and codes of practice.

6. Based on what we know now, should consumers do anything differently when using spices?

The FDA is not recommending that consumers change their consumption or use of spices. Under new FSMA regulations, facilities will be required to implement preventive controls for hazards in foods, such as pathogens such as Salmonella that may be associated with certain spices. Moreover, in many cuisines, spices are added during cooking rather than at the table, and this heat treatment can reduce pathogen contamination depending on the length of cooking and temperature. It’s also important to follow basic food handling practices—cook, chill, clean and separate
