Due to the environments in which they are grown, spices and herbs often harbor microorganisms, including bacteria. These include potential spoilage organisms and pathogens of public health significance. This page includes information about the presence of microbiological hazards on spices and the control and mitigation of these hazards.

|White Paper on Microbiology
This downloadable white paper provides background information on the presence of bacteria and other microorganisms in and on spices, information about outbreaks and epidemiology, as well as an overview of the anti-microbial properties associated with spices: Microbiology of Spices Several of ASTA’s Guidance Documents include relevant information about managing biological hazards in and on spices can be accessed on the Best Practices and Guidance page. In particular, ASTA’s Clean, Safe Spices Guidance Document, Good Manufacturing Practice (GMPs) for Spices, HACCP Guide to Spices, and ASTA Guidance on Environmental Monitoring Programs are great resources.
|White Paper on Process Validation
The Food Safety Modernization Act requires that all food companies have a food safety plan in place that includes a hazard analysis and validated process controls to control any identified hazards. Potential hazards that may occur on spices include biological hazards, such as Salmonella. Manufacturers of ready-to-eat spices must have a validated process control to ensure that Salmonella is controlled. ASTA’s downloadable white paper on validation provides an overview of essential elements for companies to consider in developing programs to validate the microbial reduction processes they use.
|Salmonella Detection Methods and Laboratory Best Practices for Seasonings, Herbs, and Spice Matrices
This white paper is intended to establish best practices when testing for the presence of Salmonella spp. in seasoning blends and spices. The goal is to foster a more consistent approach to Salmonella verification testing of individual herbs and spices, as well as complex seasoning/spice blends, amongst key stakeholders in the supply chain, including secondary suppliers (regional and global).
