If you make cheese from unpasteurized milk and ship it across state lines, you already know the number: sixty days. That's the minimum aging period federal rules require before a raw-milk cheese can move in interstate commerce, held the whole time at a temperature no lower than 35 degrees Fahrenheit. It's been the rule since the late 1980s, and it hasn't moved since.
We get more questions about this one requirement than almost any other piece of federal food policy, so this week we're laying out what it does, what it doesn't, and where our advocacy work currently stands.
What sixty days is actually for
The aging window isn't arbitrary. As a cheese ages, its acidity and salt concentration rise and its moisture drops — conditions that make it harder for pathogens to survive. Sixty days at proper temperature is the threshold regulators settled on as sufficient for that natural process to do its work across most cheese types. It's a food-safety proxy, not a flavor or quality standard, and it applies regardless of how good your milk testing program is.
That's the part that frustrates some members with tight biosecurity and testing regimes: the rule doesn't flex for a creamery's individual track record. "We test more than the rule asks us to and it still doesn't move the calendar up a single day," one farmstead producer told us this spring. A wheel that would pass every safety check at day forty still can't cross a state line until day sixty. We're not the only trade group that's raised this, and we're not expecting a quick change — but a Standards Committee-led comment has gone in this cycle asking regulators to at least study whether verified testing protocols could support case-by-case exceptions for aged wheels under sixty days.
It's worth saying plainly: this is a request for further study, not a claim that the current rule is unsafe. Food-safety rulemaking moves slowly for good reasons, and we're not asking members to treat any change here as imminent.
What this means for your shipping calendar
If you're planning production runs against buyer commitments, the aging clock needs to be built into your calendar from the vat, not bolted on after. A wheel started today can't leave the state before early June under any circumstance — no expedited path exists, and no state waiver overrides the federal minimum. Several members have told us the biggest planning mistake isn't misunderstanding the sixty days, it's forgetting that "aged" means aged from make date, not from when the wheel looks ready.
We'd also remind members that labeling requirements travel with this rule: any raw-milk cheese sold across state lines needs to clearly identify itself as unpasteurized on the label, regardless of the sixty-day window being satisfied. That's a separate requirement and it doesn't go away because the aging clock has run out.
Other pricing and dairy-policy debates are moving in the background this quarter too — the kind of milk-price reform conversations that shape farm-gate income long before a wheel ever ages a day. We'll keep flagging the ones that intersect with cheese specifically, but the sixty-day rule remains the one members ask about the most because it's the one that sits directly on your shipping calendar.
If your program ships raw-milk cheese across state lines and you want your experience in the record for this comment cycle, reach out to the Standards Committee before the end of the month. Specific examples — a shipment delayed, a buyer lost to timing — carry more weight than general support.
