Visual immunoassay for detection of Salmonella in foods: collaborative study.
A collaborative study was performed in 13 laboratories to validate a visual enzyme immunoassay (EIA) procedure, TECRA, for rapid detection of Salmonella in foods. The EIA method was compared with the standard culture procedure for detection of Salmonella in 6 food types: ground black pepper, soy flour, dried whole eggs, milk chocolate, nonfat dry milk, and raw deboned turkey. Uninoculated and inoculated samples were included in each food group analyzed. There was no significant difference in the productivity of the EIA and culture procedures at the 5% level for any of the 6 foods. The enzyme immunoassay screening method has been approved interim official first action.
