A method in a computer system for increasing protein food safety, the method comprising: receiving at least one of contamination level data (210a, 210a') and external indicator data (210b, 210b'); accessing from a database stored data comprising: prior contamination level data; prior external indicator data; prior interventions associated with the prior contamination level data and the prior external indicator data; and prior actual results (240d, 240d') associated with the prior contamination level data and the prior external indicator data; selecting a subset of the prior contamination level data, the prior external indicator data, the prior interventions, and the prior actual results, where the prior contamination level data and the prior external indicator data is similar to the at least one of contamination level data and external indicator data; and determining if an effective intervention is set forth in the subset based at least partially on the prior actual results in the subset; and if an effective intervention is not set forth in the subset, causing an intervention (225b, 225b', 225d) to be output that is increased relative to the intervention in the subset. receiving at least one of contamination level data (210a, 210a') and external indicator data (210b, 210b'); accessing from a database stored data comprising: prior contamination level data; prior external indicator data; prior interventions associated with the prior contamination level data and the prior external indicator data; and prior actual results (240d, 240d') associated with the prior contamination level data and the prior external indicator data; selecting a subset of the prior contamination level data, the prior external indicator data, the prior interventions, and the prior actual results, where the prior contamination level data and the prior external indicator data is similar to the at least one of contamination level data and external indicator data; and determining if an effective intervention is set forth in the subset based at least partially on the prior actual results in the subset; and if an effective intervention is not set forth in the subset, causing an intervention (225b, 225b', 225d) to be output that is increased relative to the intervention in the subset. prior contamination level data; prior external indicator data; prior interventions associated with the prior contamination level data and the prior external indicator data; and prior actual results (240d, 240d') associated with the prior contamination level data and the prior external indicator data; selecting a subset of the prior contamination level data, the prior external indicator data, the prior interventions, and the prior actual results, where the prior contamination level data and the prior external indicator data is similar to the at least one of contamination level data and external indicator data; and determining if an effective intervention is set forth in the subset based at least partially on the prior actual results in the subset; and if an effective intervention is not set forth in the subset, causing an intervention (225b, 225b', 225d) to be output that is increased relative to the intervention in the subset.
