PURASALOpti.Form Listeria models

The PURASAL OptiForm Listeria models can help you make a broad range of cured products, from hot dogs to hams, safer. The PURASAL OptiForm Listeria Models are a unique tool for calculating the level of lactate and diacetate to control and inhibit the growth of Listeria monocytogenes in cured meat and poultry products. PURAC has now launched its 2007 model:

The OptiForm Listeria Control Model 2007 is the latest release boundary model predicting Listeria outgrowth based on both uncured and cured cooked meat products. The model is fully in line with the FSIS Interim Final Rule for the control of Listeria monocytogenes in RTE meat and poultry products that came into effect October 6, 2003 in the United States. The OptiForm Listeria Control Model 2007 is a unique tool to help calculate the level of lactate and diacetate needed to control Listeria in cured an uncured cooked meat- and poultry products for their required shelf life.

The OptiForm Listeria Control 2007 model is available on CD-ROM and can be downloaded from a website. To receive a free copy of the model please fill out the request form.
