If your history supports the move it can certainly be done. We have a small 'high risk' facility with very good environmental testing history, and do less than 10 Listeria swabs per month for it. There's still plenty of daily general sanitation related testing, and micros by lot for finished goods.
Beat me to it. OP, you're going to need to be able to defend any choice to reduce your monitoring, so I'd start with writing up a full review of your results over the past year. If there's no concerning trends, no hot spots that consistently flare up, you're in a good place to do so. I'd associate the good micro results with a review of sanitation deficiencies, also showing the sanitation program is in control and operating as intended.
Now as to how many you can get away with reducing it to... Different can of worms. 44 a week comes to 176-220 a month. Going to 10 would be a hard sell. How many spots do you have registered in your program? How often is each registered spot being tested in any given month? You'll possibly want to consider your zoning into the updated frequencies, depending on your process.
I'm currently in a corporate FSQA role over 8 different fresh cut fruit and veg plants, and our plants rotate through a list of established listeria points. They pull listeria swabs weekly: each point is tested at least once per month, though there is overlap to make sure the rooms and general areas are tested each week (ex: floor in a cutting room might have 8 separate points on the floor, and they'll hit two different once each week). Our plan details having 50% of the swabs come from the zone 2 sites, the rest spread amongst zones 3-4, and include roughly 10 discretionary random swabs per month to seek issues where we might not have something on a list. Plants vary a fair bit in size, but listeria swabs range from 160 to 230 per month based on plant size.
