Assessing Antibiotic Residue Removal from Milk Using Biochar

Numbers of ectomycorrhizae were assessed 3 years after harvesting approximately 50% of the overstory in two Douglas-fir-larch stands in western Montana, one was subjected to intensive residue removal, the other broadcast burned 1 year after harvest. Numbers of active ectomycorrhizal root tips were significantly reduced in the broadcast burned stand compared to either the intensively utilized stand or to an adjacent, undisturbed stand. This indicates that on difficult-to-regenerate sites, particularly where soil organic matter is low, it may be advantageous to dispose of slash created in partial cuts by means other than burning.

Antibiotic Residue

Objective: To investigate the extent of antibiotic-resistant bacteria and antibiotic residue contamination in fresh raw foods sold at wholesale markets in Thailand, which may be the important drivers of antibiotic-resistant bacteria colonization and antibiotic-resistant bacterial infection in Thai population. Materials and Methods: Fresh raw foods, including food from animal products, seafoods, vegetables, fruits, and honey were purchased from two large wholesale markets in Thailand. Food samples were cultured for antibiotic-resistant bacteria and tested for the presence and amount of antibiotic residue. Results: Among 521 samples for bacterial culture, 86.9% grew at least one kind of bacteria. Enterobacteriaceae were commonly isolated and were commonly resistant to ampicillin (76.7% to 100%). ESBL-producers and ceftriaxone-resistant Enterobacteriaceae were prevalent in swine and duck samples (56.7% to 91.7%). Some isolates were resistant to co-amoxiclav (13.3% to 60.0%) and cefoxitin (5.0% to 30.0%). Colistin-resistant Enterobacteriaceae were observed in pork meat (1.4%) and chicken offal (7.0%). Ertapenem-resistant Enterobacteriaceae were detected in cha-om (26.7%). Among 501 samples for antibiotic residue testing, 37.1% contained at least one antibiotic residue. Enrofloxacin was the most prevalent antibiotic residue, followed by doxycycline and tilmicosin. Although most samples contained less antibiotics than the maximum residue limit (MRL), 7.0% contained an amount of at least one antibiotic above the MRL. Conclusion: Many fresh raw foods sold at wholesale markets in Thailand were contaminated with antibiotic-resistant bacteria, and some contained antibiotic residues. Therefore, Thai people are at risk of being colonized with antibiotic-resistant bacteria and developing antibiotic-resistant bacterial infection due to consuming foods contaminated with antibiotic-resistant bacteria or containing antibiotic residues.

Tetracycline Hcl

Tetracycline HCl is one of the most commonly used antibiotics in fish farming that aims to control diseases caused by bacteria. The purpose of this study was to determine the presence and the level of tetracycline HCl antibiotic residue in freshwater fishes sold at the Segiri traditional market. The method used in this research was a standard addition ultraviolet spectrophotometry. The results showed that residue level of tetracycline HCl in freshwater fish is 192,067 μg/g – 257,409 μg/g. These result was far exceeded the maximum residue level of tetracycline class antibiotics in meat and dairy based on SNI 01-6366-2000 that limit the residue not higher than 0.1 μg/g
