Fluorescent-antibody technique in detection of salmonellae in animal feed and feed ingredients.
Comparative studies of fluorescent antibody procedure and a cultural method for the detection of Salmonella were made on 1,013 feed and feed-ingredient samples. The agreement between the two methods was 92.1%. There were more false positives (5.7%) than false negatives (2.2%). Of the 22 false negatives, 15 (68%) were obtained on meat meal. Of the total number of samples, 37% were meat meal. An additional study of 73 samples of meat meal indicated that correlation between methods was better than correlation between samples.
