TYPES OF CERTIFICATION

Kosher Michigan certifies both dairy and meat businesses, ensuring full compliance with Jewish dietary laws and proper separation of food categories.

SUPERVISION & OVERSIGHT

Supervision is conducted by Rabbi Jason Miller or a trained mashgiach (kosher supervisor).

All inspections are yotze v’nichnas—random, unannounced spot checks.

Supervisors check for:

  • Proper vegetable washing and bug inspection
  • Approved ingredients only
  • No outside food brought in

INGREDIENT APPROVAL

Strict Ingredient Guidelines

All ingredients must have a recognized kosher symbol and be approved by Rabbi Jason Miller.

No new ingredients may be introduced without prior review.

Cheese must be certified kosher. If not, it must be USDA-produced and permitted by Conservative halachic rulings (Rabbi Kassel Abelson, 1994).

CERTIFICATION DISPLAY

Transparency for Consumers

Every certified location must display a framed teudah (kosher certificate) signed by Rabbi Jason Miller.

Certification letters are dated with a clear expiration.

A Kosher Michigan window sticker must also be placed at the entrance.

Certification is void if ownership changes.

SABBATH & JEWISH HOLIDAY POLICY

Halachic Compliance for Jewish-Owned Businesses

Jewish-owned businesses must be closed on Shabbat and Jewish holidays unless a Sabbath lease agreement is in place.

Kosher Michigan uses a lease approved by Rabbi Joel Roth and the International Rabbinical Assembly.

THE KOSHERING PROCESS

Preparing Your Kitchen the Right Way

Before certification, Kosher Michigan performs a full kashering of the kitchen(s), including:

Post-kashering inspection before certification is issued

Thorough cleaning

Boiling, firing, immersion, and oven heating

EMPLOYEE EDUCATION

Training for Long-Term Compliance

New staff receive kosher training as part of onboarding.

Kosher Michigan trains all owners and staff before certification.

No outside food is allowed in the facility (unless a separate lunch area is approved).

CERTIFICATION LETTERS (TEUDOT)

Visible, Verifiable Certification

Each certified business receives a unique kosher certificate detailing its standards.
