As the recall category be classified Class 1, this is more of just an administrative function that sometimes takes longer to get applied. So not like FDA had a revelation a month later.
From the FSPCA manual, Preventive Controls for Human Foods
Recalls are actions taken by a facility to remove a product from the market that may be adulterated, misbranded, or violate regulations in some way. In other words, a product for which the FDA or a state could take legal action against the facility would be subject to a recall. It is important to note that a recall is different from a market withdrawal and stock recovery. In a market withdrawal, it is the company’s removal or correction of a distributed product which involves a minor violation that would not be subject to legal action by the FDA, or which involves no violation. A stock recovery is when the company corrects or removes a product where that product has not left direct control of the facility.
The numerical designation (i.e., I, II, or III) [is] assigned by FDA to a particular product recall to indicate the relative degree of health hazard presented by the product being recalled (FDA Hazard Guide, Chapter 14, 2018).
(1) Class I is a situation in which there is a reasonable probability that the use of, or exposure to, a violative product will cause serious adverse health consequences or death (21 CFR 7.3(m)(1));(2) Class II is a situation in which use of, or exposure to, a violative product may cause temporary ormedically reversible adverse health consequences or where the probability of serious healthconsequences is remote (21 CFR 7.3(m)(2)); and(3) Class III is a situation in which use of, or exposure to, a violative product is not likely to cause illness or injury (21 CFR 7.3(m)(3)).
