Abbott: US baby formula plant linked to national shortage resumes production

US firm Abbott says it is restarting production at a baby formula plant after its shutdown contributed to a national shortage of the baby food.

The plant in Michigan - one of America's largest - was closed in February because of contamination.

Coupled with global supply chain issues, the factory's closure led to acute shortages.

Parents were left scrambling for supplies, seeking formula from food banks, friends and doctor's offices.

Some turned to social media to try to track down baby milk, while others attempted to make their own substitutes (against medical advice).

The facility has met initial government sanitary requirements for reopening, the company said in a statement.
