Reported Illness Trends: Poultry- and Nonpoultry Salmonella Serotypes in the US (1996–2019)
A new study published in Risk Analysis analyzed trends in reported incidence of illness due to poultry- and nonpoultry-associated Salmonella serotypes in the United States from 1996 to 2019. The study found that the incidence of illness due to poultry-associated Salmonella serotypes is that there has been a declining trend over time. This means that the number of reported illnesses caused by Salmonella serotypes associated with poultry has decreased. However, it is important to note that the study emphasizes that this decline in reported incidence cannot necessarily be attributed to a decreased prevalence of Salmonella in poultry products. Additionally, the study highlights that the serotypes associated with poultry are not unique to poultry and can also occur in other food and nonfood exposure pathways. Therefore, the decreasing trend in poultry-associated serotypes does not necessarily indicate a decrease in overall salmonellosis due to poultry products. The study suggests that actions targeting enhanced Salmonella control in poultry products may not result in a detectable decline in overall salmonellosis that can be attributed to implementation of the enhanced control measures.
