Jeong JY, Kim B, Ji SY, Baek YC, Kim M, Park SH, Jung H. Effect of Flutriafol Exposure on Residue Characteristics in Pig Muscle and Fat Tissue. Food Sci Anim Resour 2022; 42:186-196. [PMID: 35028583 PMCID: PMC8728499 DOI: 10.5851/kosfa.2021.e61] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 10/13/2021] [Accepted: 10/14/2021] [Indexed: 01/10/2023] Open
Abstract
This study investigated the effect of exposure to flutriafol based on residues in
pigs. Pigs were exposed to different concentrations (0.313, 0.625, 3.125, 6.25,
and 12.5 mg/kg bw/d, n=20) for 4 wk in different treatment groups. Serum
biochemical analysis, residue levels, and histological analysis were conducted
using the VetTest chemistry analyzer, liquid chromatography mass spectrometry,
and Masson’s trichrome staining, respectively. The body weight (initial
and final) was not significantly different between groups. Parameters such as
creatinine, blood urea nitrogen, alanine aminotransferase, and lipase levels
were significantly different as compared to the control group. Flutriafol
increased the residue limits in individual tissue of the pigs in a dose
dependent manner. Flutriafol exposures indicated the presence of fibrosis, as
confirmed from Masson’s trichrome staining. These results suggest that
flutriafol affects the morphology and serum levels in pigs. The dietary
flutriafol levels can provide a basis for maximum residue limits and food safety
for pork and related products.

Jeong JY, Kim B, Ji SY, Baek YC, Kim M, Park SH, Kim KH, Oh SI, Kim E, Jung H. Effect of Pesticide Residue in Muscle and Fat Tissue of Pigs Treated with Propiconazole. Food Sci Anim Resour 2021; 41:1022-1035. [PMID: 34796328 PMCID: PMC8564320 DOI: 10.5851/kosfa.2021.e53] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 09/06/2021] [Accepted: 09/09/2021] [Indexed: 01/15/2023] Open
Abstract
This study estimated the effect of exposure to propiconazole through
implementation and residues in finishing pigs. We analyzed the expression of
fibrosis-related genes and performed histological analysis of the blood, liver,
kidney, muscle, ileum, and fat tissues. The animals were exposed for 28 d to
different concentrations of propiconazole (0.09, 0.44, 0.88, 4.41, and 8.82
mg/kg bw/d). Quantitative, gene expression, and histological analyses in tissues
were performed using liquid chromatography mass spectrometry, real-time PCR, and
Masson’s trichrome staining, respectively. Final body weight did not
differ among groups. However, genes involved in fibrosis were significantly
differentially regulated in response to propiconazole concentrations. Glucose,
alanine aminotransferase, and total bilirubin levels were significantly
increased compared with those in the control group, while alkaline phosphatase
level was decreased (p<0.05) after exposure to propiconazole. The residue
limits of propiconazole were increased in the finishing phase at 4.41 and 8.82
mg/kg bw/d. The liver, kidney, and ileum showed blue staining after
propiconazole treatment, confirmed by Masson's trichrome staining. In
conclusion, these findings suggest that propiconazole exposure disturbs the
expression of fibrosis-related genes. This study on dietary propiconazole in
pigs can provide a basis for determining maximum residue limits and a better
understanding of metabolism in pigs and meat products.
