######################################################################################### # RTE Risk Assessment of Listeria Monocytogenous Model (RTE RALM) # The "in-plant" Code # inplant model.R, April 06, 2020- interval version 35 ######################################################################################### This file provides some information on how to run the in-plant RTE Risk Assessment of Listeria Monocytogenous Model (RTE RALM). This distribution includes: - this text file - a file including R code in text format - an excel file contatining the data input - optional training video, - optional data dictionay - optional inplant model theory - zipped output folders for comparison ################################# # How to run the code ################################# # PRE-REQUISITE ################################# You will need "R", Note: the "inplant model.R" was evaluated, as reported in the FSIS Risk Assessment - Listeria monocytogenes in retail delicatessens technical report using R language. It has been tested on R version 3.6.1 (2019-07-05) on a PC, but with no warranty. You will need the libraries (and dependancies) "readxl" and "tidyverse", installed. You will need Excel installed. Put all the files in one folder (especially the r code file and the input excel file) Make sure that R refers to this directory as the working directory. Run the model For the first tries, use the data as given and then you may modify the values as you see fit. The results are in the folder "outputs1 scenario 4-2-1 haccp pre" where you have as output data in excel files and graphs in png files. If you wanted to re-run the model. it is advised that the folder name of the prior run result folder be changed. # TO CHANGE THE INPUT PARAMETERS ################################# Open the "inplant input data.xls" file. There are seven sheets each labled as:control, dose response, parameters, distributions, plants, comparisons, and Data dictionary. control: To set up the simulations control parameters (out put control, MC simulation control, and comments with meaning dose response: parameters related to dose response relationship. parameters: deterministic parameters value distributions: probablity distributions with their parameter values plants: logical values related to plants action in testing FCS and test and hold all condition comparisons: comparision of the 2002 FSIS-FDA data and expert estimate (Dr. Davi LaBaree) data Data dictionary:A dictionary of the probablity distributions used in the model. ######################################################################################### ############################## Disclaimer ########################################### Access to the model is provided to enhance understanding of the methods we used in conducting the risk assessment.
