| description | Introduction: The presence of antibiotic residues in milk and
other products livestock is a health problem which can endanger
public health. Antibiotics are used widely in animal husbandry to
treat diseases related to bacterial infections. Antimicrobial drugs
have been in use for decades in industry. They are commonly
used in livestock facilities to treat mastitis.
Aim: This study aimed to investigate antibiotic residues in pasteurized milk distributed in schools, in milk collection centers,
and in milk production factories in Gonabad city.
Materials and Methods: This cross-sectional study was conducted on 251 samples of commercial pasteurized milk packet
distributed in schools (code A), raw milk collection centers
in Gonabad city (code B), and pasteurized milk production
factories (code C) in Gonabad city. The Copan test kit of
Denmark Christian Hansen Company was used to monitor
antibiotic residues in milk. The data were analysed employing
Chi-square test and one-way analysis of variance (ANOVA) to
determine significant differences using SPSS software version
20. The significant level was considered at p<0.05.
Results: In total, 251 milk samples were collected out of which
143 (57%) were code A, 84 (33.5%) code B and 24 (9.6%) code
C. Total number of 189 samples (75.2%) were negative and 62
(24.8%) were positive. From the three types of milk samples, 41
samples (28.7%) of the code A, 18 samples (21.4%) of the code
B and 3 samples (12.5%) of the code C were positive.
In general, from the milk samples most contaminated with
antibiotics, 17 samples were positive in January and regarding
code A, 13 samples were positive in the same month. There
was not a significant difference among the three types of
milk (p>0.05). The highest number of milk samples (n=7)
contaminated with antibiotics were related to code B (38.5%).
Most positive cases were related to code A in winter. Also,
there was no significant difference among the three types of
contaminated milk regarding the year and month (p=0.164 and
p=0.917, respectively).
Conclusion: Pasteurized milk supplied in the studied city has
high level of contamination due to high use of antibiotics. A
standard limit needs to be set for the right level of residue of
antibiotics in milk to avoid the harmful effects. |
