Under California Retail Food Code §113949.2, a food employee is diagnosed with HEPATITIS A virus. Which combination of actions is required by the person in charge?

Explanation

California Retail Food Code HSC §113949.2 and §113949.4 require EXCLUSION (not just restriction) for a food employee diagnosed with Hepatitis A virus (HAV). 'Exclusion' under the code means the employee may not be in the food facility in any role — not dishwashing, not front counter, not cleaning. The reason is that HAV is shed in stool starting 1-2 weeks BEFORE symptoms appear and continuing 1-3 weeks after jaundice onset; the virus is exceptionally hardy (survives on surfaces and on hands for hours to days), the infectious dose is very low, and contamination can occur through any surface the employee touches. Action items: (1) immediate exclusion, (2) notify the local enforcement agency without delay (required for Big 6 pathogen diagnoses), (3) cooperate with the contact-tracing investigation, (4) post-exposure prophylaxis (HAV vaccine or immune globulin) within 14 days for exposed coworkers and possibly customers, (5) return only with written medical release. Options A, B, and C all keep an HAV-positive worker on premises and are non-compliant; multiple major U.S. outbreaks (e.g., 2003 Chi-Chi's outbreak, 660 sickened, 4 dead) trace to ignoring this rule.
