Ever wonder why the number of illnesses in a foodborne outbreak can increase for weeks, even after the contaminated food is off the market?
A series of events happen before public health officials can report that a case of illness is linked to an outbreak. Each event takes a certain amount of time. This time is known as the “reporting lag” or “lag window” of an outbreak. It is usually 3–4 weeks. For illnesses caused by some bacteria, such as Listeria, it may be longer. Public health officials work to speed up this process when possible.
The steps below outline what typically happens from the day someone eats a contaminated food to the day their illness is linked to a multistate foodborne outbreak investigated by CDC.*
| Bacteria | Typical start of symptoms |
|---|---|
| Campylobacter | 2–5 days |
| E. coli | 3–4 days |
| Listeria | 1–4 weeks |
| Salmonella | 6 hours–6 days |
| Vibrio | 1-2 days |

CDC and public health laboratories use a technology called whole genome sequencing (WGS) to generate DNA fingerprints of bacteria causing illness. When bacteria have nearly identical DNA fingerprints, we consider them “genetically closely related.” Illnesses caused by bacteria that are genetically closely related are more likely to have a common source, such as a contaminated food. An outbreak is an event in which a group of people get similar illnesses from a common source. Disease detectives investigate outbreaks to find out what is making people sick.
Find out how CDC uses WGS to detect and solve foodborne outbreaks.
*Most cases of illness, even those caused by common foodborne germs, are not linked to a foodborne outbreak. This can happen for many reasons. A major reason is that most illnesses are not part of an outbreak. Another reason is that germs that cause foodborne illness can also be spread in other ways, such as by water or directly from one person to another. Also, if an illness is diagnosed by a culture-independent diagnostic test, that case may not be linked to an outbreak because these tests do not provide the information needed to link it to an outbreak. In addition, many people do not seek medical care for foodborne illnesses, so their illnesses cannot be diagnosed or reported to public health officials.

Tilapia have been linked to an outbreak of Streptococcus, which affected 146 people in Singapore, prompting the FAO to issue a “risk profile report” to raise awareness of the threat.
In 2015, around 146 people became ill after eating a traditional raw freshwater fish dish in Singapore, with several people eventually having to have limbs amputated. It turns out that they had developed blood poisoning linked to a bacterium called Streptococcus agalactiae, also called Group B Streptococcus (SBS). The specific strain responsible for the outbreak was a unique sequence type 283 (ST283). A four-page factsheet, Invasive disease linked to raw freshwater fish, has just been made available, as has a more comprehensive Risk profile – Group B Streptococcus (GBS) – Streptococcus agalactiae sequence type (ST) 283 in freshwater fish.
Dr Tim Barkham, an associate professor at Tan Tock Seng Hospital in Singapore, first identified the human health risk. “Many microbiologists were surprised, as invasive GBS disease in people has not been known to be foodborne previously,” he said.
