Oral transmission may occur through:

• Ingestion of raw or partly cooked meat, especially pork, lamb, or venison containing Toxoplasma cysts: Infection prevalence in countries where undercooked meat is traditionally eaten has been related to this transmission method. Tissue cysts may also be ingested during hand-to-mouth contact after handling undercooked meat, or from using knives, utensils, or cutting boards contaminated by raw meat.[47]
• Ingestion of unwashed fruit or vegetables that have been in contact with contaminated soil containing infected cat feces.[48]
• Ingestion of cat feces containing oocysts: This can occur through hand-to-mouth contact following gardening, cleaning a cat's litter box, contact with children's sandpits; the parasite can survive in the environment for months.[49]
• Ingestion of untreated, unfiltered water through direct consumption or utilization of water for food preparation.[50]
• Ingestion of unpasteurized milk and milk products, particularly goat's milk.[51]
• Ingestion of raw seafood.[52]

As you can clearly read, one doesn't require feline anilingus to acquire the parasite.
