“…Contamination with E. coli in chicken meat obtained from supermarkets in Bangkok during 2010-2011 was 53%. 39 Some isolates of E. coli were resistant to ampicillin, cephalothin, gentamicin, co-trimoxazole, tetracycline, and/or ciprofloxacin, but all isolates were susceptible to ceftriaxone and carbapenems. 39 A study of 240 E. coli strains isolated from…”

“…[18][19][20][21][22][23][24][25][26][27][28] There are several previous microbiological surveys of food animals on farms, fresh meat samples from slaughterhouses and retail stores, exported fresh meat samples and vegetables, and stool samples from both healthy individuals and hospital patients from Thailand and several other countries. [29][30][31][32][33][34][35][36][37][38][39][40][41] Almost all of these reports emphasized the ability of foodborne bacteria in causing gastrointestinal infections, especially Salmonella, Campylobacter, and Arcobacter species, though only a few studies described antibiotic-resistant E. coli. Many Salmonella species were isolated from these samples, most of which were resistant to antibiotics.…”

Objectives: The aim of this study was to determine the prevalence of antibiotic-resistant bacteria, especially extended-spectrum beta-lactamase (ESBL) producing Escherichia coli, in samples from healthy adults, foods, food animals, and the environment in selected areas of Thailand. Methods: Samples were collected from stool specimens from adult food factory and food animal farm workers, fresh and cooked foods sold at markets, rectal swabs of healthy pigs and chickens, fresh pork meat from slaughterhouses, water samples from canals as well as fish and shrimp farm ponds, and stagnant water sources on pig farms. Antibiotic susceptibility was determined using the disk diffusion or agar dilution methods. Extended-spectrum beta-lactamase production was assayed using a double disk diffusion method. Results: Among 544 healthy adult food factory workers, 75.5% were positive for ESBL producing E. coli, while 77.3% of E. coli isolated from 30 healthy animal farm workers were positive. Amongst healthy food animals, ESBL producing status among E. coli isolates were more commonly detected in pigs (76.7%) than broilers (40%). Extended-spectrum beta-lactamase producing E. coli seemed to be more prevalent in fresh meat samples than in fresh vegetables, in fresh foods than in cooked foods, and in water samples collected from the animal farms than those from canals and fish and shrimp ponds. Conclusions: Extended-spectrum beta-lactamase producing E. coli isolates are prevalent amongst healthy individuals, foods along the food production chain from farms to consumers, and in the environment in selected areas in Thailand.

“…14,15 Boonsaner et al found that oxytetracycline can transfer into seven-striped carp ( Probarbus jullieni ) from watermeal ( Wolffia globosa ). 14 Roxithromycin was reported to have significant bioaccumulation through dietary uptake but no biomagnification potential in an artificial food chain including algae, water flea and fish. 15 These studies only included one antibiotic, and the artificial food chains investigated consisted of two or three species.…”

Little information is available about the bioaccumulation and biomagnification of antibiotics in marine food webs. Here we investigate the levels and trophic transfer of 9 sulfonamide (SA), 5 fluoroquinolone (FQ), and 4 macrolide (ML) antibiotics, as well as trimethoprim in nine invertebrate and ten fish species collected from a marine food web in Laizhou Bay, North China in 2014 and 2015. All the antibiotics were detected in the marine organisms, with SAs and FQs being the most abundant antibiotics. Benthic fish accumulated more SAs than invertebrates and pelagic fish, while invertebrates exhibited higher FQ levels than fish. Generally, SAs and trimethoprim biomagnified in the food web, while the FQs and MLs were biodiluted. Trophic magnification factors (TMF) were 1.2 – 3.9 for SAs and trimethoprim, 0.3 – 1.0 for FQs and MLs. Limited biotransformation and relatively high assimilation efficiencies are the likely reasons for the biomagnification of SAs. The pH dependent distribution coefficients (logD) but not the lipophilicity (logKOW) of SAs and FQs had a significant correlation (r = 0.73; p < 0.05) with their TMFs. Although the calculated estimated daily intakes (EDI) for antibiotics suggest that consumption of seafood from Laizhou Bay is not associated with significant human health risks, this study provides important insights into the guidance of risk management of antibiotics.

“…In addition to direct toxic effects of the pollutants, some of them can also accumulate along the food chain, resulting in long-term ecological and health hazards. [1] A wide variety of pollutants are currently being continuously introduced into aquatic environments via domestic sewage, agricultural runoff and industrial effluents. These pollutants include a wide range of toxic and persistent substances such as certain pesticides, pharmaceuticals, heavy metals, nanoparticles and residues of these.…”

The effect of the microalgae Chlorella vulgaris on a wide range of different pesticides in water was studied. Treatments included short-term exposure (1 h) to living and dead microalgal biomass and long-term exposure (4 days) to actively growing microalgae. The initial pesticide concentration was 63.5 ± 3.9 µg L(-1). There was no significant overall reduction of pesticides after short-term exposure. A significant reduction of the total amount of pesticides was achieved after the long-term exposure to growing microalgae (final concentration 29.7 ± 1.0 µg L(-1)) compared with the long-term control (37.0 ± 1.2 µg L(-1)). The concentrations of 10 pesticides out of 38 tested were significantly lowered in the long-term algal treatment. A high impact of abiotic factors such as sunlight and aeration for pesticide reduction was observed when the initial control (63.5 ± 3.9 µg L(-1)) and the long-term control (37.0 ± 1.2 µg L(-1)) were compared. The results suggest that water treatment using microalgae, natural inhabitants of polluted surface waters, could be further explored not only for removal of inorganic nutrients but also for removal of organic pollutants in water.
