Answer:
Toxoplasma gondii
Explanation:
Toxoplasma gondii is a single celled parasitic organism. It is found in cat feces. It can cause toxoplasmosis by consumption of contaminated meat, coming in contact with infected cat feces or from mother to child during pregnancy. Most people do not develop symptoms but people with weak immune system and babies may develop flu like symptoms. The symptoms are headache, bodyache, swollen lymph nodes, fever and fatigue.
Since Todd had cleaned the cat litter box and forgot to wash his hands afterwards, he might have come in contact with the cat feces. The parasite was transferred from the feces to his hands from where it was transferred to the food which the customers ate and hence they call came down with flu like symptoms.
