Companies usually start a recall weeks before the FDA classifies and publishes it; the gap above is that lag.

Reason for recall

Due to a design change in 2015, corrosion on the sample probe electrical contacts can occur and lead to a disturbance of the sample liquid level detection (LLD). When disturbance of the sample liquid level detection (LLD) occurs, the affected sample probe may dip into the sample material deeper than intended. This may lead to carryover and medical risk cannot be excluded.

Lead and other heavy metals accumulate in the body. Children are most at risk; even low levels can affect development.
