U.S. Customs and Border Protection (CBP) said officers in Kentucky last week intercepted a shipment of fentanyl from South Africa that was labeled as "water purification."

The package arrived in Louisville on Sept. 21 and contained enough "lethal doses" of fentanyl to kill 220,700 people, CBP said.

Officers found a bottle labeled "Hydrozone ph-Balance" containing a white powder that tested positive for fentanyl. A small zip lock bag labeled "Bicarbonate minerals" also contained a white powder that tested positive for the deadly narcotic.

The total amount of fentanyl seized was 441 grams. The agency said the estimated street value was $58,000.

Another zip lock bag labeled as "Magnesium mix" was also found inside the shipment. It contained 32.8 grams of a white crystal substance that tested positive for cocaine.

The shipment was destined for a residence in Littleton, Colorado, the agency said.

"Our officers are committed to keep our country and communities safe from illegal and dangerous drugs," Louisville’s Port Director Thomas Mahn said in a written statement. "This seizure is one example of the quality enforcement work they do on a daily basis."

Since September 1, the agency said officers in Louisville have seized 17 pounds of cocaine, 20 pounds of fentanyl, 83 pounds of steroids, 119 pounds of ketamine, 123 pounds of heroin, 141 pounds of methamphetamine and 251 pounds of marijuana. 

The total street value of these drugs was estimated to be over $4.6 million.

Fentanyl is a synthetic opioid that "is approximately 100 times more potent than morphine and 50 times more potent than heroin as an analgesic," according to the Department of Justice’s Drug Enforcement Administration.
