The US FDA has issued a warning that cans of Genova tuna, which were recalled due to the risk of contamination with Clostridium botulinum bacteria, were mistakenly shipped to stores in several states[2]. The recalled products include Genova's tuna in olive oil in 5 oz packages with an expiration date of January 17, 2028[1]. Botulism is caused by the ingestion of foods containing a neurotoxin produced by the bacterium Clostridium botulinum[1]. Symptoms of intoxication include severe fatigue, weakness, dizziness, blurred vision, and difficulty speaking and swallowing, and the toxin can cause paralysis of the respiratory muscles and death[1]. Symptoms usually appear 18 to 36 hours after ingestion of the toxin, but can occur 4 to 8 days after exposure[1]. The Center for Food Safety has been investigating whether the recalled products have reached Hong Kong, and preliminary investigations have not identified local sales or imports of the affected batches[1].
