Ghana- Investigation into the risk of exposure to antibiotic residues contaminating meat and egg
27 Nov. 2010
Food Control [edited] [BITES]
In Ghana little is known about food safety in relation to antibiotic residues. The objectives of the study were to determine the prevalence of antibiotic residues in animal source food and estimate the risk to consumers and identify factors predisposing animal source food to contamination with antibiotic drug residues. A total of 634 samples of various animal source foods, including beef, pork, and egg were screened for drug residues. Additionally, epidemiological data related to antibiotic usage on animals and consumption patterns of animal source food was collected from animal farmers and consumers of animal source food respectively. The findings of this study underscore the importance of health education of farmers in dealing with the problem of drug residues contaminating animal source food.
The scale of illegal meat importation from Africa to Europe via Paris
21 June 2010
Wiley Interscience [edited] [ProMED]
A new research study in the scientific journal, Conservation Letters, estimates that five tones of illegal bushmeat from Africa is smuggled in personal luggage each week through one of Europe's busiest airports. Working alongside customs officials at France's Roissy-Charles de Gaulle airport, researchers from the Zoological Society of London (ZSL), The Royal Veterinary College (RVC), and The National Veterinary School and the Natural History Museum of Toulouse, identified 11 bushmeat species from confiscated luggage, including species of primates, crocodiles, and pangolins. Thirty-nine percent of the confiscated bushmeat was identified as being listed under the Convention for the Trade in Endangered Species, highlighting the unsustainable nature of the trade and its potential impact on species of conservation concern. In addition, the illegal trade of such large quantities of bushmeat raises serious questions about the importation of pathogens into Europe. This is the first systematic study of the scale and nature of this international trade. Much of the bushmeat smuggled into Europe is for personal consumption.
Ethiopia- Prevalence and antimicrobial resistance of Campylobacter isolates from humans and chickens in Bahir Dar, Ethiopia
01 Jun 2010
Foodborne Pathogens and Disease. 7(6): 667-670. doi:10.1089/fpd.2009.0433 [edited][FSNet]
In this study, the isolation and antimicrobial resistance of Campylobacter jejuni and Campylobacter coli strains from chickens and humans in Bahir Dar, Ethiopia, were analyzed. Two hundred and ten human and 220 chicken samples were analyzed between October 2007 and April 2008. Seventeen human and 160 chicken Campylobacter species were isolated. The overall prevalence of thermophilic campylobacters was 8% and 72.7% in humans and chickens, respectively. In humans, 94.1% of the isolates were C. jejuni and 5.9% were C. coli. C. jejuni was a predominant species of thermophilic campylobacters in all categories of patients. In chicken, 92.5% of thermophilic campylobacters isolated were C. jejuni and 7.5% were C. coli. Among the 16 isolates of C. jejuni in humans, 18.8%, 12.5%, 12.5%, 18.8%, 25%, and 22.2% were resistant to ampicillin, ciprofloxacin, erythromycin, nalidixic acid, streptomycin, and tetracycline, respectively, whereas among the 148 C. jejuni isolates from chicken, 17.5%, 14.9%, 12.2%, and 13.5% were resistant to ampicillin, erythromycin, streptomycin, and tetracycline, respectively. Among the 12 isolates of C. coli in chicken, 16.6%, 8.3%, and 16.6% were resistant to ampicillin, streptomycin, and tetracycline, respectively. The overall level of resistance was not significantly different in C. jejuni and C. coli isolates of both humans and poultry. The detection of resistant isolates for commonly used antimicrobials may cause a threat to humans and chickens by limiting therapeutic options.

Senegal-Microbiological quality of milk from small processing units

Consumption of milk and dairy products has increased significantly in Senegal in the last decade, and a large part of the local production comes from small processing units spread all over the country. Researchers collected 85 bulk-tank milk samples from 68 smallholder dairy farms throughout the territory. Microbiological quality of milk samples was analyzed according to the official standards. Further, raw milk and pasteurized milk were screened for Mycobacterium bovis, Coxiella burnetii, and anti–Brucella abortus antibodies. Ninety-three percent of pasteurized milk samples, 92% of raw milk samples, and 81% of sour milk samples failed to meet official standards. Pathogens detected in milk were C. burnetii (6/41, 15%), which seems to be endemic in Senegal, coagulase-positive staphylococci (18/70, 26%), and Salmonella Johannesburg in one sample. Further analysis of coagulase-positive Staphylococci isolated from samples containing more than 104 colony-forming units per gram showed the presence of enterotoxigenic strains in 9 of the 10 samples. These results confirm the poor microbiological quality of milk produced by small units in Senegal, especially and surprisingly of pasteurized milk. This highlights the need to implement good hygiene practices, particularly in the postpasteurization process, and an effective monitoring throughout the production and delivery chain.
