Food consumption and practices have changed throughout the world during the past 20 years. We are observing a shift from the typical localized point source, or “church supper” outbreak, which is relatively easy to detect, to the more diffuse, widespread outbreaks that occur over many communities with only a few illnesses in each community.
This is the result of increased industrialization of the food production. Food produced in one place may be sold and consumed in a geographically distant area . If the product is contaminated at low-level or consumed by relatively few people, the result may be an outbreak with so few cases in each location that it is not noticed locally. However, by collecting and comparing data from different areas, it may be possible to detect such dispersed outbreaks. In this context, PulseNet has revolutionized the way outbreaks are recognized and investigated.
