This study assessed whether using a form of esterified formic acid (30% formic acid) in drinking water (10 kg/1000 L) 5 days before slaughter could be a helpful strategy to mitigate this public health issue. Thus, 240 pigs from three Salmonella-positive commercial fattening farms were selected. From each farm, 40 pigs were allocated to a control group (CG) and 40 to a treatment group (TG). At the abattoir, fecal samples from both groups were collected for Salmonella detection (ISO 6579-1:2017) and quantification (ISO/TS 6579-2:2012). Salmonella was present in 35% (95% IC = 29.24–41.23) of the samples collected. The prevalence was significantly higher in the CG than in the TG (50% vs. 20%; p < 0.001). In all farms, the TG showed a lower percentage of shedders than the CG. A random-effects logistic model showed that the odds of shedding Salmonella were 5.63 times higher (95% CI = 2.92–10.8) for the CG than for the TG. Thus, the proportion of pigs shedding Salmonella that was prevented in the TG due to the use of this form of organic acid was 82.2%. In addition, a Chi-squared analysis for trends showed that the higher the Salmonella count, the higher the odds of the sample belonging to the CG. These results suggest that adding this type of acid to drinking water 5 days before slaughter could reduce the proportion of Salmonella-shedding pigs and the Salmonella loads in the guts of shedder pigs. info:eu-repo/grantAgreement/ES/MICINN/RTI2018-093915-B-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.7 2023 VETERINARY SCIENCES 16 / 167 = 0.096 2023 Q1 T1 AGRICULTURE, DAIRY & ANIMAL SCIENCE 10 / 80 = 0.125 2023 Q1 T1 0.698 2023 Veterinary (miscellaneous) 2023 Q1 Animal Science and Zoology 2023 Q1 4.9 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Marín-Alcalá, Clara María (orcid)0000-0002-1974-9025 Vico, Juan Pablo Mainar-Jaime, Raúl Carlos Universidad de Zaragoza (orcid)0000-0001-5442-7702 1009 773 Universidad de Zaragoza Dpto.
