aEQAP, egg quality assurance program. This analysis included 11 states that had state- or industry-sponsored EQAPs and 9 states with state-sponsored EQAPs. Departments of agriculture and health provided technical advice, supervision, and monitoring to state-sponsored EQAPs. State-sponsored required auditing by third parties, tested eggs for contamination with S. Enteritidis if layer houses were found to be positive, and diverted eggs found to be contaminated with S. Enteritidis to pasteurization and hard cooking.
