Novolyze, a company specialized in Preventive Control Validation, recently announced the addition of 4 new references to its SurroNov range of dry and ready-to-use surrogate microorganisms. With these new products, Novolyze offers an off-the-shelf solution to the food industry for assessing the impact of a thermal process - such as baking, extrusion, drying, etc. - on the inactivation of Salmonella. The released products aim at facilitating preventive control validation studies for the following food applications:
Nuts & Seeds (SurroNov 1822)
Pet Food & Animal Feed (SurroNo 1824)
Herbs & Spices (SurroNov 1826)
Biscuits & Snacks (SurroNov 1832)
These four new items have been tested to have a similar / greater resistance than Salmonella in their respective food application. Tests included inactivation studies on such food matrices as kernel pistachios, pet food kibbles, black pepper, paprika and cookie dough.
As a reminder, surrogate microorganisms are non-pathogenic bacteria that mimic the behavior of foodborne pathogens to different kinds of stress (heat etc.). Since they are not pathogenic, they can be safely used in-plant to validate the efficacy of a preventive control, a cornerstone requirement of FSMA. SurroNov surrogate microorganisms are commercialized as a ready-to-use powder preparation that does not require any further enrichment step before use. They are available in individual pouches from 25g to 1kg at concentrations up to 10-log CFU/g. Their inoculation on a food product is usually obtained by blending.
Novolyze has already announced the launch of new surrogate references in the near future, to cover different food applications.
