Antibiotic Residue Monitoring Results for Pork, Chicken, and Beef Samples in Vietnam in 2012–2013

Abstract

A monitoring plan of residual antibiotics in food of animal origin was conducted in Vietnam from 2012 to 2013. Meat samples were collected from slaughterhouses and retail stores in Ho Chi Minh City and Nha Trang. A total of 28 antibiotics were analyzed using a LC-MS/MS screening method. Sulfonamides, fluoroquinolones, and tilmicosin were detected in some of the samples. Sulfaclozine and fluoroquinolones were mainly detected in chicken samples, and sulfamethazine was mainly detected in pork samples. High levels of sulfonamide residues, ranging between 2500 and 2700 μg/kg sulfaclozine and between 1300 and 3600 μg/kg sulfamethazine, were present in two chicken and three pork samples, respectively. Tilmicosin was detected at ranges of 150-450 μg/kg in 10 chicken samples. Positive percentages were 17.3, 8.8, and 7.4% for chicken, pork, and beef, respectively, for an average of 11.9%. The results suggest an appropriate withdrawal period after drug administration had not been observed in some livestock.

Characteristics of Extended-Spectrum β-Lactamase–ProducingEscherichia coliin Retail Meats and Shrimp at a Local Market in Vietnam

“…The use of large volumes of antibiotics in food-producing animals has been proposed as a contributing factor (Vieira et al, 2011). In this regard, we confirmed residual antibiotics in a significant number of meat samples in a different study (Yamaguchi et al, 2015).…”

“…Moreover, recent reports from Vietnam showed that antimicrobials are extensively used in large-scale pig and poultry farming (CarriqueMas et al, 2015;Dang et al, 2013). In fact, residual antibiotics in a significant number of food samples were observed in Vietnam (Yamaguchi et al, 2015). These circumstances may contribute to the high rates of MDR ESBL-producing bacteria in food in Vietnam.…”

Antimicrobial Usage and Antimicrobial Resistance in Animal Production in Southeast Asia: A Review

“…Sulphonamides, fluoroquinolones, and tilmicosin were detected. Sulfaclozine and fluoroquinolones were mainly detected in chicken samples, whereas sulfamethazine was mainly detected in pork samples [25]. Another study from Vietnam investigating fluoroquinolone and tetracycline residues in 104 fish/shrimp retail samples concluded that overall 27% of retail samples tested positive for either of the two, using a range of techniques [17].…”

Antibiotic Pollution in Marine Food Webs in Laizhou Bay, North China: Trophodynamics and Human Exposure Implication

“…25 In order to reduce the potential exposure risks, more strict maximal residue limits (MRL) of antibiotics in seafood need to be set for Chinese residents. While consumption of seafood alone is unlikely to represent a major human health risk in China, humans are exposed to antibiotics by a variety of other exposure pathways, such as other food intakes, 58,59 drug abuse, 60 tap water, 61 and inhalation of contaminated dust. 62 Moreover, this study did not investigate levels of antibiotic metabolites in the food web from Laizhou Bay.…”
