The SafeX Pro ExchangeCenters for Disease Control and Prevention announced Monday that 22 toddlers across 14 states were poisoned by lead found in recalled applesauce packets.

The 1-to-3-year-old patients presented with high blood lead levels ranging from 4 to 29 micrograms per deciliter and with common symptoms of lead poisoning, according to the announcement.

The recall expanded from Wanabana brand products to the private label brands of Schnucks grocery stores and Weiss grocery stores earlier this month.

The cases were reported in Alabama, Arkansas, Louisiana, Maryland, Missouri, New Mexico, New York, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Texas and Washington.

Parents should not buy, eat or feed these pouches to their children.

Those who believe their kid may have consumed the recalled products should "contact their child’s healthcare provider about getting a blood test," the CDC advised.

Here is a timeline of the apple sauce packet recalls.
