Sentence examples for microbial screening methods from inspiring English sources

Consequently, during the last decade this has led to the development of improved microbial screening methods.

Some of the studies concerning microbial screening methods do not intend to cover the entire spectrum of antimicrobial residues, but only a specific group of antibiotics.

Monitoring of food products from animal origin for the presence of antimicrobial residues is preferably done using microbial screening methods because of their high cost-effectiveness.

So far only a few microbial screening methods claim to have been validated "according to 2002/657/EC" [ 36, 37, 51, 59].

Some studies evaluating the performance of microbial screening methods use tissues originating from animal medication experiments [ 47, 49, 56], but the production of incurred materials for each antibiotic at the appropriate concentration is a difficult and expensive task.
