How to remove rows from cell array based on multiple conditions?

I would like to separate the following sample array into 2 arrays. If C contains any of the following strings (red, spoon, fork) within the row, I want to remove the row and put it into a new cell array.
clear all
clc
% Sample cell array
C = [{'A1';'A3';'A4';'A7'},{'blue';'green';'red';'blue'},{'spoon';'fork';'knife';'cup'},num2cell(rand(4,1))];
idx = cellfun(@(x) strcmp(x, 'red', 'spoon','fork'), C(:,:));
% Extracted data
C1 = C(idx,:);
% Others
C2 = C(~idx,:);
new arrays should look like...
C1 =
'A1' 'blue' 'spoon' [0.6948]
'A3' 'green' 'fork' [0.3171]
'A4' 'red' 'knife' [0.9502]
C2 =
'A7' 'blue' 'cup' [0.0344]

E.g., assuming your columns are nice and are not mixed class:
C = your cell array
S = your cell string compare array, e.g., {'red', 'spoon','fork'}
x = cellfun(@ischar,C);
Cx = reshape(C(x),size(C,1),[]);
y = any(ismember(Cx,S),2);
C1 = C(y,:);
C2 = C(~y,:);

OK, since your columns can have mixed data type, I have converted my code to loop over the rows:
m = size(C,1);
y = true(m,1);
for k=1:m
x = cellfun(@ischar,C(k,:));
y(k) = any(ismember(C(k,x),S));
end
C1 = C(y,:);
C2 = C(~y,:);
