A ongoing labor strike at US East Coast and Gulf Coast ports is causing disruptions to the food supply chain, including the import of beef, seafood, and export of chicken. The strike has led to the backlog of over 50 container ships and could result in food shortages or price inflation. The beef sector is particularly affected as the US is experiencing tightened domestic beef supplies due to a severe drought and high grain prices, leading to a decline in the herd size and a surge in beef prices. The strike comes at a critical time as retail prices for ground beef have hit a record high of $5.58 per pound.
