reasons for the use of antibiotics
application of antibiotics – a scandal?
main point: development of resistances
other consequences
affected products
scandals
chemical analysis
Reasons
• therapy of diseases caused by bacteria
• In animal fattening farms
A Scandal?
• 2006 law by the European Union
– only apply to diseased animals
– prescribed by a veterinarian
– document the therapy
– maximum amounts
• large-scale defiance of this law is recognized
as a scandal
Development Of Resistances
• wrong application
• same agents for animals as for humans
Other Consequences
• polluted air
• antibiotics reach plants and soil
Affected Products
• meat and meat products
• Other animal products
(cheese, eggs etc.)
• „wholefood products“
• honey
• grain, salad, other
vegetables
Preventive Measures
• Sufficient heating
• Seperate fresh products from raw meat
Food Scandals
• 2001 illegal sale of antibiotic-containing
medicine
• 2001 Asian shrimps are contaminated with
Chloramphenicol
• 2002 these shrimps are processed to feed
• 2002 Nitrofurantoin in poultry from Brazil and
Thailand
• 2002 antibiotics in Chinese honey
Food Scandals
• 2011 high amounts of antibiotics in poultry
from German farms
• 2013 chicken legs are polluted with too many
bacteria
Chemical Analysis
• LC-MS method
• Advantages:
– Large spectrum of compounds analyzable
– No derivatization necessary
– Small amounts detectable
• Not validated yet
Chemical Analysis
• construction of the equipment
Chemical Analysis
• Other methods:
– Enzyme Immunoassays
– GC-MS
– Capillary electrophoresis
Discussion
• Avoidance of animal fattening
– The best solution?
– Are there others?
• We as consumers
– Which possibilities do we have?
