Salmonellosis in quantify July

In quantify July we’d like to highlight different numbers and figures in different ways. So far we have talked about the estimated benefits of good silage practices and facts and figures about the industry we are working in.

The topic we want to highlight today is about food-borne Salmonellosis; This is still a big issue we see today is food-borne zoonoses. Salmonellosis is the most frequent one we still have. At a global level, the main resources for infection for humans include meat products, and mostly the consumption of poultry meat. In spite of the control measures implemented in the production, there has been a shift in salmonella serotypes related to poultry and poultry production and especially associated with the spread of certain well-adapted clones. Antimicrobial resistance in non-typhoidal Salmonella is considered one of the major public health threats related to meat production.

In developing countries, the main source of non-thyphoidal Salmonella is the intestinal tract of food producing animals. Which can lead to contaminated foodstuffs. Food-borne salmonellosis is the most relevant source with a high global impact in human health. It was estimated that non-typhoidal Salmonella causes around 93.8 million illnesses and 155 000 deaths each year worldwide. In the USA, more than 1 million annual cases of food-borne salmonellosis were estimated by the CDC; they were associated with the largest number of hospitalizations and deaths compared with other food-borne microbial agents. In Europe, salmonellosis has been the second most common zoonosis (82 694 confirmed cases and 20.4 cases per 100 000 population in 2013) and the most frequent cause of food-borne outbreaks, in spite the reported decreasing trend that has resulted from Salmonella control programs.

Although different serotypes have been associated with salmonellosis, a limited number are responsible for most human infections; S. enterica Enteritidis being the most frequent one in the EU (39.5% in 2013) and USA (14.5% in 2012) followed.

Continuous monitoring to detect the emergence of any serotype or new clone along the food chain is of critical importance for public health, warning of the emergence of new Salmonella food safety risks, involving foodstuffs like poultry meat, which is one of the most consumed and increasing globally traded meat products.
