Is sous vide cooking safe?

Yes, when following established time and temperature guidelines. Bacteria are eliminated at sustained temperatures — 130°F for 2+ hours pasteurizes beef. The Anova and Joule apps include safety-validated times.

Do I really need a vacuum sealer to start?

No. Ziploc bags with the water displacement method work perfectly for 90% of beginner cooks. Invest in a vacuum sealer later when you're committed to the technique.
