What Is a TCS Food?
TCS stands for Time/Temperature Control for Safety. A food is classified TCS when it can support the rapid growth of harmful bacteria or toxin formation if left at the wrong temperature for too long. These are foods that, without refrigeration or proper temperature management, could make someone sick.
Oklahoma's Official Definition
Under the Homemade Food Freedom Act, a TCS food is defined as: "Food that requires time or temperature control for safety to limit infectious or toxigenic microorganisms and is in a form capable of supporting rapid and progressive growth of infectious or toxigenic microorganisms."
A food is not classified TCS if it has a pH of 4.6 or below, or a water activity (aw) value of 0.85 or less. Meet either of those thresholds and your product is shelf-stable — no TCS rules apply.
Common indicators that a product is likely TCS: it contains dairy (milk, cream, cheese, eggs in a liquid or custard form), cooked proteins, or any ingredient that would spoil within a few hours at room temperature. When in doubt — and especially for anything you'd normally keep in the refrigerator — treat it as TCS.
Oklahoma's TCS Requirements — Step by Step
Selling TCS foods in Oklahoma is absolutely permitted — but it comes with three clear requirements. Meet all three and you're operating legally under the HFFA.
Prepared Meal & TCS Product Status
The table below covers common prepared food products and their classification under Oklahoma's HFFA. Use this as a starting reference — always confirm borderline products with lab testing or an ODAFF inquiry.

Food Safety Training for TCS Sellers
If you plan to sell any TCS food — even occasionally — you must complete an ODAFF-approved food safety training course first. Both options below are available online and can be completed at your own pace.
Other ODAFF-approved training courses may also qualify. Contact the ODAFF Food Safety Division at (405) 522-6119 to confirm whether a specific course meets the requirement before enrolling. [VERIFY: confirm complete approved course list with ODAFF]
How TCS Delivery Works
The delivery requirement is one of the most important distinctions between TCS and non-TCS products in Oklahoma. For perishable foods, the exchange must always be producer to consumer — directly and in person.
Online sales of TCS products are permitted — you can take orders through your website, SellFood storefront, or social media — but the physical exchange must happen in person, either through pickup at your home or personal delivery by you.
